Biology: Fish Dissection
For biology, we purchased a few dissection animals in a kit. In the particular kit, we ordered there were seven animals. A perch, frog, crawfish, earthworm, lubber grasshopper, starfish, and clam. This is the fish dissection.
These type of dissections are just up our alley. No, I’m not the typical squeamish girl that runs from a bug or gets really grossed out seeing a dead animal on our hiking path. In fact, I’ll be the first one to pick up a stick and start poking it. 🙂 This part of my being didn’t develop until after the birth of our first son because there was a time that any insect would send me running. 😉
The kit came with all the tools needed for dissection, as well as instructions for each animal.
|I love that you can see the excitement and anticipation on his face.|
|Making the first cut, to expose the gills.|
|There is a bony covering over the gills that must be removed in order to examine them.|
A small part of the gills exposed. The instructions suggested examining them under a microscope. Once we get one, I think we will order another specimen and try this dissection again.
There is a large sac, the air sac, that helps to keep the fish floating. I was too interested in learning with the boys I forgot to get a photo of it, once they removed it. In this photo, you can see it in the exact middle of this animal’s body.
Examining the eye. The boys were fascinated with how different the eye was, compared to how we THOUGHT it would be.
I love learning with the boys. I am looking forward to dissecting the rest of the animals. We’ll get a microscope soon, to be able to examine the tissue samples with.
