Odorein

Odorein are small, omnivorous, fanged wyverns that have adapted to life in cold water. This monster makes its first appearance in Monster Hunter: Evolution.

Physiology
Odorein superficially resembles a walrus in shape and form but is actually a highly specialized species of Fanged Wyvern. The head of an Odorein is nearly identical to that of a lystrosaurus and its tusks are similar to a walrus, the flippers of this monster look more similar to webbed feet than actual flippers and even have claws at the end of the digits. The forelimbs are large in size than the hindlimbs but other than that they are identical in shape. Its skin is covered in small non-overlapping scales with small keratin scutes appearing along the back and neck.

Behavior
Despite being slow and cumbersome monsters of small size, Odorein males, are shockingly aggressive and are known to attack other males and even hunters that wonder in their territory.

Abilities
These monsters posses no specialized organs or glands that have elemental abilities, but their beaked and tusked jaws can deliver a painful bite.

Taxonomy
Odorein are a small species of fanged wyvern that are part of the same subfamily as Cynodama. Like all fanged wyverns Odorein is very distantly related to fanged beasts but posses many more primitive reptilian traits than their hairy cousins.
 * Order: Therapsida
 * Suborder: Dicynodont
 * Family: Shansiodontidae
 * Subfamily: Cynodamasauria
 * Genus: Odorein
 * Species: O. rosmarus

Habitat Range
Odorein have only been found inhabiting the coastal waters of the Glacial Ruins and the surrounding ice flows of this locale. Due to them being highly adapted to this landscape they are incapable of surviving in warmer waters.

Ecological Niche
Odorein are omnivores that rest on the bottom of the food chain in the icy waters they inhabit. Due to their blubber rich meat and slow and cumbersome bodies they easily fall prey to many carnivores they share their environment with. They are heavily preyed upon by the fanged beasts Arcynauos and Pinnilontra as well as many ocean dwelling predators like Sharq. Odorein themselves are hunters of bivalves, small shellfish and seagrasses.

Biological Adaptations
Due to a thick layer of blubber underneath their skin they are able to easily resist the freezing waters they inhabit. They are also capable of entering short states of dormancy when food is scarce allowing them to reserve energy and feed less.

Behavior
Odorein males are highly territorial of each other but will allow harems of females and their young to stay on their stretch of beach. They are known to gather in large groups composed mainly of females and young for protection against smaller and less bold predators.
