Transcript of Glaucus Atlanticus

The Glaucus Atlanticus lives throughout the world's oceans, mostly in tropical waters. The most common places to find it would be the south and east coast of South Africa and the east coast of Australia.
The Glaucus Atlanticus, like most of
this report says, is also very unusual in its reproduction. The Blue Slug is what is called a hermaphrodite, meaning it is both genders in one. It lays 12-20 eggs on each string and it taks 11 days hatching and 3 days as larvae. It does not care for its babies.
Glaucus Atlanticus
The Glaucus Atlanticus is a small nudeabranch or sea slug that that floats on the ocean surface and grows up to 3 cm in length. It is also a close relative of the Glacilla Marginatus.
Kingdom: Animalia
Phylum: Mollusca
Class: Gastropoda
Family: Glaucidae
Genus: Glaucus
What's interesting about this picture
is that what looks like its top or back
is actully the belly because it has controlable gases in its stomach that makes its belly float upward.
Also it has interesting camouflage so that when birds look at it from above has blue and when fish look at it from below it has a pale grey back to blend in with the surface.
The Glaucus Atlanticus has some very unusual
eating habits; it usually feeds on the
Portuguese Man 'O' War or the Blue Bottle.
Both are a type of jellyfish, but when it eats one
of these, it consumes the venom, too and when
it does it pushes the venom into its own
tentacles to use it as its own defense.
This creature has distinct blue markings running up and down its body with a silvery, grey background. When it is an adult the Glaucus Atlanticus can be up to 3 cm in length. It has a tapering body which is flattened, and has six appendages which branch out into rayed, finger-like cerata (which is Greek for horns).
