astronomy-to-zoology:

Aegires minor (no common name)

is a species of dorid nudibranch found in Indo-pacific waters from Japan to Australia. like alot of nudibranchs they are fairly small only growing up to 5 inches long. They are best known for their bright yellow color with a series of black lines covering their body. A. minor feeds mostly on species of calcareous sponge of the family Lecuettidea but will eat other species as-well.

rhamphotheca: The Blue Dragon aka Blue Sea Slug (Glaucus atlanticus) The blue glaucus likes to snack on hydrozoans (relatives of jellyfish). It’s especially fond of the tentacles of the highly poisonous Portuguese man-of-war. The blue glaucus is adapted to deal with the Portuguese’s stinging cells without getting hurt. Instead, it deters its own potential predators by storing the swallowed poison inside the finger-like structures sticking out of its body. Pretty nifty!  (read more: Encyclopedia of Life) (photo by Tien–Cheng Wang via World Register of Marine Species)

eduardo-: At first glance, you would think you are staring at some hydroids or sponges. But what you are seeing is a transparent anatomy of a newly discovered nudibranch. It’s easy to see how such a unique slug avoided discovery until recently. The Melibe genus is unique in comprising of active predators versus the typical Nudibranch that feed on sessile inverts. Therefore, this transparent camouflage makes evolutionary sense. Melibe colemani was first discovered by the late great underwater photographer, Neville Coleman. He passed away back in May of this year. He was an epic naturalist, underwater explorer, and an amazing photographer. While we as aquarists don’t usually specifically try to keep nudibranch unless we’re trying to get Berghia to graze some aiptasia but they really are cool marine animals. More details about the Nudi and its discoverer can be found here. A big thanks to Jim Walters for turning us on to this very cool sea slug.

Pitted Ceratosoma (Ceratosoma miamiranum) It has a relatively hard mantle with a series of rounded lobes around the edge. Smaller specimens have many compound tubercles and usually there is a median longitudinal ridge and a series of ridges running out from the longitudinal ridge to the mantle edge. As specimens grow in size these ridges can partially disappear. Mandati Jetti, Wangi-wangi Island Wakatobi Photo by me (Lyra)

Loch Chromodoris (Chromodoris lochi) Chromodoris lochi is blue or blueish-white with typically three dark or black longitudal lines running down the body. Individuals can reach at least 34 mm in length. There is some variation between individuals in this species, and the gills and rhinophores range in color from a translucent straw-color, through to pink and light orange.
