Marine Ecology Blog 1 By: Elizabeth Hargis & Shannon Ashworth Odobenus Rosmarus ( https://www.mmc.gov/wp-content/uploads/walrus2_shutterstock.jpg ) Introduction: The Odobenus Rosmarus, more commonly known as the walrus, is a marine mammal belonging to the genus Odobenus and is further divided into three subspecies. This large marine mammal can be found within the waters of the arctic ocean (O. r. rosmarus), the pacific ocean (O. r. divergens), or the laptev sea of the arctic ocean (O. r. laptevi). Anatomy The anatomy of a walrus is very interesting in that it allows them to be both land and marine animals.

And although both males and females have tusks, the male tusks are wider and longer than those on the females. Tusks can grow up to three feet in length and can weigh up to twelve pounds

While they typically roam these waters alone, the plural form of octopus is octopuses, not octopi as many believe.   There are close to 300 species of octopuses. Octopuses are a part of the Cephalopoda class, which also includes cuttlefish, squids and nautilus.   These intelligent creatures live fascinating lives.   Let’s dive in and take a look at the places they call home, the ways they “get it on” and how they fight off those cruel enemies.
