reproduction and social behaviors of P. hydrobothynus

The stellar river otter is an incredibly territorial and aggressive animal. The males will monitor their territory daily while foraging for frogs, and fights between neighboring, and young males happen frequently. When a young male is able to defeat a dominant male who is in charge of a pride he is able to take over the male’s pride. Many young males go around challenging other males but due to their lack of experience and size, they are very easily beaten. The male stellar river otter maybe six to eight years old before he is able to finally get a female of his own, but then he must spend the rest of his days defending his territory from rival males. The stellar river otter may live to be 20 years old and will spend its time defending its territory to the very end.
