Glaucus atlanticus is a species of small, blue sea slug, a pelagic aeolid nudibranch, a shell-less gastropod mollusk in the family Glaucidae. These sea slugs are pelagic; they float upside down by using the surface tension of the water to stay up, where they are carried along by the winds and ocean currents. Wikipedia

Kingdom: Animalia
Phylum: Mollusca
Class: Gastropoda
Order: Nudibranchia
Suborder: Cladobranchia
Family: Glaucidae
Genus: Glaucus
Species: G. atlanticus

Are Blue Dragon sea slugs poisonous: For this reason, the Blue Glaucus poses a much greater threat to humans than the Portuguese man o' war. Picking one up may result in a painful sting and symptoms similar to those of its prey. These include nausea, vomiting, and pain. But like other sea slug species, the Blue Glaucus itself isn't venomous.

The snakeheads are members of the freshwater perciform fish family Channidae, native to parts of Africa and Asia. These elongated, predatory fish are distinguished by their long dorsal fins, large mouths, and shiny teeth. They breathe air with gills, which allows them to migrate short distances over land. Wikipedia

Family: Channidae; Fowler, 1934

Order: Anabantiformes

Phylum: Chordata

Class: Actinopterygii

Kingdom: Animalia

Suborder: Channoidei; Berg, 1940

Can snakeheads walk on land: Snakehead fish have evolved to “walk” on land! They propel themselves forward by moving their head and back fin in opposite directions. Underwater, a snakehead absorbs oxygen through its gills, just like other fish.


How long can a snakehead fish live out of water: Because snakeheads are obligate air-breathers, they can live in poorly-oxygenated stagnant water. Out of water, they can survive for up to four days.
