This is Dante. He is loosely based off of a Goblin Shark.
The only one who has met him is Felicity, but when you try to ask her about him, she's nowhere to be found...
He came out a little too anthro-y for my tastes but I like his teeth. his face reminds me of Erin Jaeger
It's hard to tell, but he is about the size of Ivory, give or take.
