Blue Dragon Sea Slug

I’m working on a post I’m anxious to have done, so I’ll just quote the photo’s description on Flickr:

    my brother and i found one of these guys floating in a rockpool the other day, looking for all the world like a little blue chinese dragon. i’d never seen anything like it and i had absolutely no idea what it was at first. but i applied my considerable (ahem) natural history talents and came up with an answer – turns out it IS a blue dragon, a pelagic sea slug which floats about the ocean on its back (that’s it’s belly and foot you’re looking at) feeding on blue bottles. so very cool, is it not?

(I apologize for the site’s weird behavior as of late. It’s probably not the greatest idea to play around with settings on a live site! I will perform a minor software update tonight, then post a (arguably major) project I’ve been working on.)

This was a very interesting passage, though it was written 9 months ago. But I wish I knew more about it, like where it came from, etc.

I found several of these washed up on shore the other day and scooped one up in a shell with a little water int it. Did you know thatthey can also squirt out small amounts of dye like squid and octopus do? At least this one did when I had him on the shell.

Anyway, this thing was to cool and so out of this world beautiful in a wierd way.

Some more information:

These guys are highly poisones! They eat Portuguese-Man-o’War and use their prays’ stinging cells for their own defense and hunting! They have both male and female parts and lay their eggs in “strings”. They were discovered in 1777 and were named after the Roman god of the sea Glaucus.

I like how people see something like this and automatically want one for a pet without knowing anything about it. Yea it’s cool but think about it… let’s grab all these little creatures up so people can have them, until they’re all gone and extinct. That’s why there isn’t anything cool left on this planet. That’s why are planet is dying. That’s why we have as many problems as we do. Humans are really dumb most the time!
