The full extent of these human threats on giant otters are’nt well understood yet. I think they did this just to differentiate True Giants from lesser giant types in the game mechanics. The giant otter is clearly distinguished from other otters by morphological and behavioural characteristics. Other water habitats include freshwater springs and permanent freshwater lakes. The giant otter is also rare in captivity; in 2003, only 60 animals were being held.[3]. Barnett, Adrian; Shapley, Rebecca; Lehman, Shawn; et al. [10] Later gene sequencing research on the mustelids, from 2005, places the divergence of the giant otter somewhat later, between five and 11 million years ago; the corresponding phylogenetic tree locates the Lontra divergence first among otter genera, and Pteronura second, although divergence ranges overlap.[16]. The estrous cycle is 21 days, with females receptive to sexual advances between three and 10 days. The Guianas are the last real stronghold of the giant otter. [53] Other researchers suggest approximately 7 square kilometres (2.7 sq mi) and note a strong inverse correlation between sociality and home range size; the highly social giant otter has smaller home range sizes than would be expected for a species of its mass. One full-year study of giant otter scats in Amazonian Brazil found fish present in all fecal samples. [49] In some cases, supposed cooperative hunting may be incidental, a result of group members fishing individually in close proximity; truly coordinated hunting may only occur where the prey cannot be taken by a single giant otter, such as with anacondas and the black caiman. [61] While still present in a number of north-central countries, giant otter populations are under considerable stress. Marmi, Josep; Lopez-Giraldez, Juan F.; Domingo-Roura, Xavier (November 2004). The giant otter largely subsists on a diet of fish, particularly characins and catfish, and may also eat crabs. [45], The longest documented giant otter lifespan in the wild is eight years. [63][64] Water pollution from mining, fossil fuel extraction, and agriculture is a serious danger; concentrations of pesticides and other chemicals are magnified at each step in the food chain, and can poison top predators such as the giant otter. [22] Guard hairs trap water and keep the inner fur dry; the guard hairs are approximately 8 millimeters (one-third of an inch) in length, about twice as long as the fur of the inner coat. No institution, for example, ... Dry season range size analysis of three otter groups in Ecuador found areas between 0.45 and 2.79 square kilometres (0.17 and 1.08 sq mi). One report suggests maximum areas 28 m (92 ft) long and 15 m (49 ft) wide, well-marked by scent glands, urine, and feces to signal territory. Gutleb, A.C.; Schenck, C; Staib, E (December 1997). One report found between three and eight campsites, clustered around feeding areas. (October 2002). Duplaix documented interaction with the neotropical otter. For a better experience, please enable JavaScript in your browser before proceeding. Male giant otters can attain a length of 1.5-1.7m (4.9-5.6ft). Some sea otters might get heavier. “Feeding Ecology of the Giant Otter. The Giant squid, considered to be the largest living invertebrate, is a cephalopod that finds its habitat in temperate to subtropical marine waters. The Asian small-clawed otter is the smallest otter species and the giant otter and sea otter are the largest. Adventure Game Industry Market Research Summary (RPGs) V1.0, TSR, WotC, & Paizo: A Comparative History, Eric Noah's Unofficial D&D 3rd Edition News, Enchanted Trinkets II for D&D 5th Edition, Good Fantasy campaigns, system immaterial. Its distribution has been greatly reduced and is now discontinuous. Schenck et al., who undertook extensive fieldwork in Peru in the 1990s, suggest specific “no-go” zones where the species is most frequently observed, offset by observation towers and platforms to allow viewing. It is the longest member of the Mustelidae, or weasel family, a globally successful group of predators, reaching up to 1.7m (5.6 ft). Farmers follow, creating depleted soil and disrupted habitats. It has no serious natural predators other than humans, although it must compete with other species, including the neotropical otter and caiman species, for food resources. Two river dolphins, the tucuxi and boto, might potentially compete with the giant otter, but different spatial use and dietary preferences suggest minimal overlap. “Biology and conservation of Giant Otter (, Creative Commons Attribution-ShareAlike License. The implementation of CITES in 1973 finally brought about significant hunting reductions,[5] although demand did not disappear entirely: in the 1980s, pelt prices were as high as US$250 on the European market. Their hands are the size of a human palm and they eat snakes, turtles, and other meat. The giant otter shrew (Potamogale velox) inhabits southern Africa and is more widely distributed than the other otter shrews. The fact that it is exclusively active during the day further suggests its eyesight should be strong, to aid in hunting and predator avoidance. Its dental formula is I 2 3 C 1 1 P 3 3 M 3 3 = 38. The giant otter is clearly distinguished from other otters by morphological and behavioral characteristics. A page allowing the comparison of up to six figures is now available. Newborn pups squeak to elicit attention, while older young whine and wail when they begin to participate in group activities.[29]. Ribas, Carolina; Mourão, Guilherme (January 2005). Fish from the order Perciformes, particularly cichlids, were seen in 97% of scats, and Characiformes, such as characins, in 86%. ), while females average 22 to 26 kg (49-57 lbs.). This otter is the largest member of the family Mustelidae, clearly distinguished from other South American otter species by morphological and behavioural characteristics. A 21' foot humanoid is totally huge as it is. Subadults leaving in search of new territory find it impossible to set up family groups. Many people find this particular Otter to be different in size and shape from others. The Giant Otter features a very long body, similar to that of a weasel. The South American giant otter and the sea otter are bigger. For me, bumping them up 24' tall shrinks them. [41] Females have a gestation period of 65 to 70 days, giving birth to one to five pups, with an average of two. [51], Local people sometimes take pups for the exotic pet trade or as pets for themselves, but the animal rapidly grows to become unmanageable. Otters are generally considered to be small and fluffy animals, but there are 11 other species of otter. When mining and deforestation occur in an area, the otters can be directly affected because the river banks they live on and depend on can be badly destroyed. They noted that the species may be the basal divergence among the otters or fall outside of them altogether, having split even before other mustelids, such as the ermine, polecat, and mink. It is really: if I use enlarge on the fighter (or he/she is a rune knight), do I want the fighter to be as big as a frost giant? The giant river otter. Body length is up to 40 ins (110 cm) – not including tail. [28] Duplaix identified 9 distinct sounds, with further subdivisions possible, depending on context. [40] The animal reaches sexual maturity at about two years of age and both male and female pups leave the group permanently after two to three years. 2014.3) due primarily to exploitation of their natural habitat, illegal harvesting of their pelts, and persecution for perceived impact on depleting local fish [44] This sensitivity is matched by a strong protectiveness towards the young. The species was listed as endangered in 1999 and wild population estimates are typically below 5,000. Londono, G. Corredor; Munoz, N. Tigreros (2006). (1990). Hagenbeck, Carl; Wunnemann, Claus (1992). Utreras, V.; Suárez, E.; Zapata-Ríos, G.; et al. [31] A capacity for aggressive behavior should not be overstated with the giant otter. A 110lb sword, 14' foot long, and 8" broad is huge. When in the water, the giant otter faces danger from animals not strictly preying upon it: the electric eel and stingrays are potentially deadly if stumbled upon, and piranha may be capable of at least taking bites out of a giant otter, as evidenced by scarring on individuals. All group members may aggressively charge intruders, including boats with humans in them. Weights are between 26 and 32 kg (57 and 71 lb) for males and 22 and 26 kg (49 and 57 lb) for females. The size of adult lions varies across their range with those from the southern African populations in Zimbabwe, the Kalahari and Kruger Park averaging around 189.6 kg (418 lb) and 126.9 kg (280 lb) in males and females respectively compared to 174.9 kg (386 lb) and 119.5 kg (263 lb) of male and female lions from East Africa. The giant squid can grow to an enormous size and is characterized by having a head, a mantle with two large fins, eight arms, and two tentacles. It is one of the most endangered mammal species in the neotropics. In other otter species, vision is generally normal or slightly myopic, both on land and in water. Other indirect impacts are also likely to harm them. Giant otters in the wild can eat caiman, piranhas, and anacondas. Giant otters build dens, which are holes dug into riverbanks, usually with multiple entrances and multiple chambers inside. The giant otter (Pteronura brasiliensis) is a South American carnivorous mammal. Defense against intruding animals appears to be cooperative: while adult males typically lead in aggressive encounters, cases of alpha females guarding groups have been reported. and weighing just 1 to 5 kg (2.2-11 lbs.). Different otter species vary in size. (2001). Fish remains were of medium-sized species that seem to prefer relatively shallow water, to the advantage of the probably visually oriented giant otter. [23] Its velvety feel makes the animal highly sought after by fur traders and has contributed to its decline. The growth in giants is simply another example of number inflation for it's own sake which has been infecting every new addition of D&D. Because, bigger numbers means better, right? The smooth-coated otter (Lutrogale perspicillata) of Asia may be its closest extant relative; similar behaviour, vocalizations, and skull morphology have been noted. They have quicker reflexes than anacondas, are better swimmers than crocodiles, and eat piranhas for breakfast. Decades of poaching for its velvety pelt, peaking in the 1950s and 1960s, considerably diminished population numbers. I hope you like reading on Otter vs Beaver vs Muskrat fight comparison. “Breeding the giant otter (. Two subspecies are currently recognized by the canonical Mammal Species of the World, P. b. brasiliensis and P. b. paraguensis. [68] In a report for World Wildlife Fund in 2002, Duplaix was emphatic about the importance of Suriname and the other Guianas:[51], Other countries have taken a lead in designating protected areas in South America. The giant otter of South America can grow up to 5.6 feet from snout to toe. But this is a long process and inefficient against multiple opponents because, while the human is doing this to one otter, the other would attack him. Schenck, Christof; Jessica, Groenendijk; et al. [2] Populations in Bolivia were once widespread but the country became a “black spot” on distribution maps after poaching between the 1940s and 1970s; a relatively healthy, but still small, population of 350 was estimated in the country in 2002. Guyana is immediately to the west and French Guiana is immediately to the east. The Giant River Otter only lives in three river systems: the Amazon, Orinoco and La Plata. [50], The IUCN listed the giant otter as “endangered” in 1999; it had been considered “vulnerable” under all previous listings from 1982 when sufficient data had first become available. They appear in a fish poisoning legend where they assist a man who has wasted his sexual energy, creating the anacondas of the world from his distressed and extended genitals. [32] Duplaix suggests a division between “residents”, who are established within groups and territories, and nomadic and solitary “transients”; the categories do not seem rigid, and both may be a normal part of the giant otter life cycle. [57], Even if without direct predation, the giant otter must still compete with other predators for food resources. It's less of a mechanical impact as well now that reach is disassociated from size/height in a linear way. I like how the "Large-sized" true giants (hill, stone, fire, and frost from 3e) grew up to be "Huge-sized" in 5e. The giant otter is diurnal, being active exclusively during daylight hours. (April 1999). [14] Carter and Rosas found average areas a third this size. Change ), You are commenting using your Google account. In addition to the usual insects and snails, its diet also includes crabs, prawns, fish, and frogs. Change ), You are commenting using your Facebook account. All otters have webbed feet to help propel them through the water, and most species have sharp claws. This page was last modified on 19 August 2014 at 17:04. Note that this is an XHTML+SVG page. [51] It is found in freshwater rivers and streams, which are generally seasonally flooded. The three Guianas remain the last stronghold of giant otters in South America, with pristine giant otter habitat on some rivers and good giant otter densities overall—still, but for how long? The giant otter is a highly social animal and lives in extended family groups. Well suited for an aquatic life, it can close its ears and nose while underwater. Males are between 1.5 and 1.7 m (4.9 and 5.6 ft) in length from head to tail and females between 1 and 1.5 m (3.3 and 4.9 ft). Habitat requirements and availability were presumed to be dramatically different in the rainy season: range sizes of 1.98 to as much as 19.55 square kilometers (0.76 to 7.55 sq mi) were estimated for the groups. Fernando, Rosas; Zuanon, Jansen; et al. Charlotte England @charlottengland. [50], Other species that prey upon similar food resources include the caimans and large fish that are themselves piscivores. Fonseca, Fabrizio R.D. Communal latrines are adopted adjacent to the campsites, and dens with a handful of entrances are dug, typically under root systems or fallen trees. Funny, I was about to say how I disliked that the large sized giants grew up to be huge sized. [39], Suriname still has significant forest cover and an extensive system of protected areas, much of which protects the giant otter. Behavior and conservation of the Amazon’s giant river otter. It has the greatest body length of any species in the mustelid family, although the sea otter may be heavier. [31] In another instance in Brazil, a carcass was found with clear indications of violent assault by other otters, including bites to the snout and genitals, an attack pattern similar to that exhibited by captive animals. The giant otter ranges across north-central South America; it lives mostly in and along the Amazon River and in the Pantanal. It has the greatest body length of any species in the mustelid family, although the sea otter may be heavier. Other threats to the giant otter include conflict with fishermen, who often view the species as a nuisance (see below). [61] The animal’s relatively late sexual maturity and complex social life makes hunting especially disastrous.[5]. The otter can attack from both above and below, swiveling at the last instant to clamp the prey in its jaws. The giant otter’s highly sensitive whiskers (vibrissae) allow the animal to track changes in water pressure and currents, which aids in detecting prey.

Below is the generic otter-human size comparison. So in other words, the actual physical reality of the giant becomes less and less important as it's height increases. [44], The giant otter is very sensitive to human activity when rearing its young. The IUCN lists Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Paraguay, Peru, Suriname, and Venezuela as current range countries. Poaching has long been a problem. [21] The fur is extremely dense, so much so that water cannot penetrate to the skin. [2] Given local extinctions, the species’ range has become discontinuous. How does it actually effect play?
