Blue Dragon Sea Slug, what is it?

Floating upside down through the ocean, the blue dragon sea slug lurks awaiting its’ prey.  Often called the blue ocean slug or sea lizard, the blue dragon sea slug actually camouflages itself with its silver back facing down and its large blue foot facing upwards.  The blue dragon sea slug uses both surface tension and stomach gas to accomplish this feat of floating upside down.

It should be noted that the blue dragon sea slug is indeed a slug, even in the absence of a shell that most slugs inhabit.  However when these hermaphrodite lays strings of eggs that later develop into larvae, the larvae are encased in a shell.  Once the larvae develop further, the blue dragon sea slug loses the shell and grows amazingly aesthetic tentacles.

These beautiful tentacles with finger like appendages capture the eye but can cause quite the sting.  The tips of each finger or tentacle are armed with nematocysts that are found only on cnidarians.  The blue dragon sea slug is a feared predator among the ocean.  They eat just about anything floating about, large or small.  Larger than bite size prey are cut apart by the radula or toothy tongue.  Interestingly, the blue dragon sea slug also eats the well known ocean predator, the Portuguese Man o War, as it is immune to the stings.  Blue dragon sea slugs’ stomach sorts through the nematocysts, choosing on the most potent ones.  Then, the nematocysts are transferred to those beautiful tentacles for their next poisoning sting.
