GameTavern - Goblin SHark vs. Hoatzin

Goblin Shark:

Quote:

The pink coloration, unique among sharks, is due to blood vessels underneath a semi-transparent skin (which bruises easily), thereby causing the coloring. The fins have a bluish appearance. Goblin sharks lack a nictitating membrane. They have no precaudal pit and no keels. The front teeth are long and smooth-edged, while the rear teeth are adapted for crushing.

Hoatzin:

Quote:

This is a noisy species, with a variety of hoarse calls, including groans, croaks, hissing and grunts.[8] These calls are often associated with body movements such as wing spreading. Calls are used to maintain contact between individuals in groups, warn off threats and intruders and by chicks begging for food.
