Also known as sea swallow, blue sea slug, blue angel or blue dragon, it is a small sized sea slug that lives in the Atlantic, Indian and Pacific ocean.
They feed mainly on other sea creatures like the Portuguese Man-o-War, a cnidarian often mistaken for a jellyfish. The Glaucus is immune to their venom, and can actually store it in its cerata ( their dorsal and lateral outgrowths on the upper surfaces of the body). As a result they can sting potential predators. The sting is quite painful for humans, so they should be handled carefully. At times, and given the occasion, they can be cannibalistic.
With the aid of a gas-filled sac in its stomach, the Glaucus floats at the surface. Due to the location of the gas sac, the sea swallow floats upside down.
Like almost all heterobranchs, Glaucus is a hermaphrodite, having both male and female reproductive organs. After mating, both animals produce egg strings.
This was the result of me complaining about how annoying fur was to paint during the pride wolf series and my housemates telling me to do pride slugs instead. Could have gone with the standard land slugs but of course I had to make my life difficult and went with a blue sea slug. Nudibranchs are neat, especially when dolled up in the asexual colours so this little guy now has a spot in the lounge..
Glaucus atlanticus is a species of small blue sea slugs.
These sea slugs are pelagic: with the aid of a gas-filled sac in its stomach they are able to float upside down on the surface tension of the water, where they are carried along by the winds and ocean currents. They are found in temperate and tropical waters such as South Africa, European waters, the east coast of Australia and Mozambique.
These sea slugs are so cool but I wasn’t sure how to translate their unique design into a Shellos ;v;
(did you know? The blue striped side you always see in pictures is actually the bottom (aka the “foot”) of the Glaucus atlanticus. The top is actually silvery. They float upside down right below the water’s surface and the blue stripes serve as camouflage from birds and other predators!)
