Crocafish

An animal with a crocodile like snout and fish gills, from the Jurassic period. This large fish is a vegetarian. It’s snout shape makes an upwards curl looking like a smile. It has round nodules on its spine to protect it from predators by appearing like boulders on the bottom on the water basin when still.

It’s also a term used in disc golf, when failing miserably.
