Photohunter: Yellow




This is a black dorid (Polycera atra) that I caught feeding on some bryozoans I collected for my thesis. I have caught at least four different species of nudibranch (sea slugs) as I am collecting their main food source, but I think this one is my favorite for its coloration. These nudibranchs tend to e a little toxic, as they concentrate the toxins from their food source in their tissues, so the beautiful patterns are used to warn off would-be predators. Some nudibranchs take a different route, and use their coloration to blend in with their food source so well, it is hard to see them even when you look very closely.

  4. Cool!

    Our chiropractor's office has a large aquarium and we always follow the goings on of the fish in it. Friday morning, I was looking over and noticed something small flitting about. On closer inspection it appeared that there were at least two baby fish in the tank. Apparently, there were at least 5 but it appears that they are down to two... We are all hoping that the two manage to avoid the other grown-up fish until they are too big to eat.

    It is the first time I have seen baby tropical fish "on the hoof" so to speak.
