Marine Biology
Glaucus Atlanticus
The Blue Dragon
Usually found in the pelagic regions of the Pacific, Atlantic, or Indian Ocean
Feed mainly on hydrozoans, but have been know to be cannibals
A big part of their diet is the Portuguese Man-o-War
They eat the Man-o-War with the fired and unfired stinging cells (nematocysts) and will pass these stings into special pouches in their cerata which they then use for defence.
They are immune to the Man-o-War's nematocysts.
These blue slugs use something called rhinophores to seek out their prey. A rhinophore is essentially a sense of "smell."
They use chitinous which are its teeth
Life Cycle
Live a pelagic life
They keep air in their stomachs that allow them to stay afloat on the surface of oceans.
They are holoplanktonic
They live from a month to a year.
They are hermaphrodites
They reproduce by sticking their penises into each other and fertilize each others eggs.
They have the second longest penis compared to its body length in the animal kingdom. The first is barnacles.
They keep air in their stomachs that allow them to stay afloat on the surface of oceans.
Their ability to eat stinging cells and they are not effected. In fact, they use if for their own benefit.
The slug stores the stolen nematocysts in the cnidosacs in the ends of their cerata, or tentacle like structures at the end of the "arms," for future use
