The Jawfish are a Family of ray-finned fish, characterised by their large heads, eyes and mouth and the single dorsal fin running the length of their body. This fish favours warmer water and use his large mouth to dig out and remove sand. In this manner he creates himself a protective burrow. His main diet is plankton and other small organisms, and he always remains near his home. This Yellow-headed fellow can grow to lengths of 10cm, although the Giant Jawfish can measure up to 50cm. He is a mouthbrooder, and will carry the eggs until they hatch.
