Manatee
Scientific Name: Trichechus manatus
Class: Mammalia
Diet: Herbivore
The manatee, affectionately called the “sea cow,” is a gentle giant with a wonderfully rotund body. Typically weighing between 880 and 1,200 pounds, its plump shape glides slowly through warm, shallow waters.
Interestingly, the manatee’s roundness comes largely from its enormous digestive system, needed to process huge amounts of aquatic plants. Its bulk helps it stay stable and buoyant while grazing for hours each day.
Manatees inhabit the warm coastal waters, rivers, and springs of the southeastern United States, the Caribbean, and parts of South America.
As voracious grazers, manatees keep waterways healthy by trimming aquatic vegetation. Boat collisions, habitat loss, and cold stress have made them Vulnerable.
Fun Fact: A manatee can eat up to 10% of its body weight in plants every single day.
Walrus
Scientific Name: Odobenus rosmarus
Class: Mammalia
Diet: Carnivore
The walrus is a massive, blubbery marine mammal whose rounded body is a marvel of cold-weather engineering. Weighing up to 1.5 tons, it carries a thick layer of fat that keeps it warm in frigid Arctic seas.
Moreover, the walrus’s blubber is far more than padding. This insulating fat lets it survive icy waters, fuels long dives, and provides energy during lean months when food is scarce.
Walruses inhabit the Arctic waters and ice floes of the Northern Hemisphere, foraging on the seabed for clams and other shellfish.
As bottom-feeders, walruses stir up nutrients that support the Arctic food web. Melting sea ice from climate change poses a serious threat, leaving them Vulnerable.
Fun Fact: A walrus uses the sensitive whiskers on its snout to detect shellfish buried in the dark seabed.
Hippopotamus
Scientific Name: Hippopotamus amphibius
Class: Mammalia
