  • Heard recently on the "Epic Win FTW" site, in regards to a sea creature that looks like a tiny alien. The species depicted there was identified by a commenter as glaucus atlanticus:

    “Glaucus atlanticus is a species of medium-sized, floating, blue sea slug, a pelagic aeolid nudibranch, a marine opisthobranch gastropod mollusk in the family Glaucidae.”

  • I would just like to relate that on yesterday's (Nov 13th 2009) advanced proficiency test administered by the Cervantes Institute, one of the 'comprehension texts' was totally given over to the nudibranch. O, mejor dicho, el nudibranquio.

    Who said hanging out on Wordie wasn't edumacational in a practical sense?

  • Nope. I'm a gill-less wonder.

  • :D

    I love sproingy rhinophores, evidently. (You wouldn't happen to be a hypothetical nudibranch, would you, mollusque?)

    August 25, 2008

  • I love "sproingy." :-)

    August 24, 2008

  • Wonderful associations, she!

    The front sproingy things are rhinophores and the rear sproingy things are gills, as modeled by this Chromodoris. Some nudibranchs also have cerata in between, which are more balloony than sproingy.

  • The word coloratura is apt for such beauty. . ..

    August 22, 2008

  • Prettiest comment ever on Wordie, she.

    August 22, 2008

  • Lovely, she! :-)

  • O, nudibranchs! Dream-spun mollusks!

    You look like flowers, and forests! And psychedelic bonnets! Like hippopotamus gardens, and—and this! With sproingy things!

    You lay egg-spirals. You masquerade as the world's teensiest whales! I would build for us a house with walls made out of fishtanks..!

    But I have garden slugs. :<
