Homalopsines are water snakes who have:
- dorsal-oriented eyes
- valvular nostrils, and
- rear fangs (venomous)
Like this lil fellow here:
(ok, but the fangs don't show.. just imagine them curved backward)
This is a cerberus rynchops, a dog faced water snake.
Doesn't look like a dog to me at all, if anything a snakey crocodile.
Remember, the word is
HOMALOPSINES
