Mr Turra's Deep Sea Dragon Fish



The Deep Sea Dragonfish. Looks utterly horrible. Evidently is a ferocious predator but is very small (approx. 14cm). It lives in the deep oceans of the world - about 1.5km down in tropical oceans.  Its head is large and has some extraordinary looking teeth.  The glowing thing attached to its chin is called a barbel and is used to lure other fish close (to eat) like a fishing lure. This barbel is tipped with a light-producing organ known as a photophore. It can flash on and off and wave back and forwards. The dragonfish also has photophores along the sides of its body. These are used to attract a mate during mating season.Check out the clip from Nemo which shows a similar fish using the photophores to attract Dory and Nemo.
