The Crocodilefish or Cymbacephalus beauforti is a very odd saltwater fish that gets it name from its crocodile like appearance as you can see in the pictures. Also known as the Crocodile Flathead, and the De Beaufort's Flathead, these fish are members of the Scorpaeniformes order which makes them close relatives to Stonefish and Scorpionfish.
Looks very similar to the moray eel my brother-in-law caught while fishing off the pier in Bodrum. Not quite what he was expecting to catch. Putting it back in the water was as frightening as its teeth.
