Hello. I know at least one person asked for an update on the Raja erinacea
embryo I shot a picture of for the gallery a while ago. I thought I would also share with you guys some other stuff in the lab at school, as it's pretty neat. At least I think so.. But first up, here's the little skate as of today, 3/24. The first photo was the first one I took on 2/25. I was told it was seven months through its gestation then, though now I'm not entirely sure. I'll check on it though. I would have taken more in-betweens but I was on Spring Break and doing test stuff. :)
Next up is a yellow tang that I'm doing a comparison study with (I'm comparing it with the little skate). This tang and several other saltwater and freshwater fish were donated by a local pet store- they had died en route. When I first looked at this guy I saw no signs of illness- it was still the very bright yellow color of a living tang. Here, it is being stained so that its organs will be visible. This is a shot of it with the stain on it..
And here is one where I held up the jar to the light so you can see the effects of the staining process so far. I adjusted the brightness and contrast on this picture so it's more noticeable, but so far you can just start to see the outlines of the bones and organs. When it's done it will be essentially as if the fish had see-through scales.
Lastly, our lab houses a lot of different critters. I don't know exactly what species this is or what it's doing there, but I really like this crab. It's the size of a small dinner plate. It lives in a tank with a continuous flow of water, so that's why the image looks a little warped here. The water is overflowing down the side of the tank into the touch pool below (where there are starfish, scallops, etc.).
Another picture of the crabby, this time from the side. Sometimes I wonder if it isn't just a lab pet. There's a few of those hanging around.
Hope you guys enjoyed these. Sorry if anyone looked at this who is grossed out by biology stuff (like staining dead yellow tangs).
