The larger blue organisms are Glaucus Atlanticus,
The smaller blue ones being Glaucus Marginatus
Wonder how the G. Atlanticus is able to consume all that venom? It is totally immune. This creature instead eats the venomous nematocysts whole, collects them in cnidosacs at the tip of those feather-like `fingers`, and concentrates the venom for its own use as defense!
( This is all the info I could find online concerning it`s digestion)

Reproduction
Reproduction
Like most of it`s kind, G. Atlanticus is hermaphroditic. However, they cannot reproduce individually; after finding a mate, both animals produce egg strings.. These egg strings then either float freely on water, or stick to a nearby surface! (Be it another animal or a piece of driftwood)
Open circulatory system! (assumed due to it being in the Gastropod class)
The bright blue color this creature is famous for is actually it`s underside! The G. Atlanticus floats upside down in order to expose the bright colors and camouflage with the waves... It`s back is a silver-grey to hide from the underwater predators!
