Serina: Fishing Circuagodont (Patreon)

Concept sketch I did for a wading heron-like predaceous circuagodont back when Serina was still at 255 MYH. A biped with a coiled raptorial back leg which it can launch out with lightning speed to snatch up fish and other aquatic prey, with highly curved claws and hooked spines covering the inner edges to cling to their slippery, squirming prey.

A number of very long whiskers on the underside of the throat feel the water for the faint vibrations of swimming animals in the shallows when it dips its head just about the water's surface. 

I recall Sheather did not really like the idea as it was depicted so it never really became a thing, although the sawjaws later coincidentally became bipedal and semi-aquatic too.
