on the topic of "animal cousins":

last night, when i was ahem, high, i tried to remember the difference between these three animals:

the sea otter.


the walrus.


and the seal.



ALSO, the difference between these two animals:



the rhino.


and the hippo.

i have, in turn, concluded that these two groups of animals are "animal cousins". taadaa!

and, i think this guy, is a cousin to both groups:
the manatee.
