Description

Also known as Blue Dragon, Blue Dragon Sea Slug, Blue Glaucus, Blue Ocean Slug, Blue Sea Dragon, Blue Sea Lizard, Blue Tide Animal, Glaucus Atlanticus Sea Slug, Nudibranch, Pokemon Sea Slug, Sea Lizard, Sea Swallow, The Blue Fleet.

Found upside down on the surface of the water, using their gas filled sac to swallow air bubbles to maintain their buoyancy, drifting with the winds and currents throughout the worlds oceans.
They feed exclusively on the Bluebottle - Portuguese Man-o-War
Length - 4cm
Depth - Surface
Circumtropical

These beautiful sea slugs can also sting because they recycle the stinging cells from the Portuguese man-o-war to use for their own defence.

Opisthobranchia - Nudibranchs - Sea Slugs meaning "naked gills" are molluscs without a hard shell.
All opisthobranchs are hermaphrodites.
These beautiful slugs are usually brilliantly coloured and this in itself can act as a deterrent against predators. Some sea slugs secrete acid from stinging cells in their tentacles while others secrete acid from cells in their mantle.
Nudibranchs are slow moving, can swim or be propelled along either by muscular contraction or by millions of tiny hairs on the bottom of a fleshy 'foot', they have a voracious appetite and feed with a rasp like tongue.
Nudibranch lay their eggs in a ribbon effect on the sand, in different colours depending on species. Ref: http://www.seaslugforum.net/showall/glaumarg
