Eucaron is a pokémon unique to Sehto of type Blood and Water.

Its general appearance is one of a medley between snake and shark - it is far too longer for any regular shark shape to hold true to it, but the rest of it speaks a clear language in that regard, fins, flippers and tail unmistakable. Instead of having actual gills, Eucaron merely has tribal markings like stylised lightning bolts along its neck, and breathes with lungs - but certainly lives in the ocean. Its skin is smooth in one direction and rough and dangerous to the touch in another, much as with real sharks, though the crimson colour is an unusual deviation.
