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. 😉

Perch Dissection Kit

 

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.

Making the first cut to expose the internal organs.

Examining the kidneys.

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.

Removing the organs, to gain access to the stomach.

Examining the eye. The boys were fascinated with how different the eye was, compared to how we THOUGHT it would be.

Here you can see the lens, the iris (the black part) and the pupil.

This is the pupil. As with every eye of every animal, the pupil is made from a very hard material.


Scraping away the skull, to gain access to the brain.

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.

  • Hey Carrie, just an FYI the correct name for a starfish is a sea star. We took educational boat cruise a few years ago down in Charleston and it was explained to us that they had been misnamed. It isn't a fish so the name was changed to a sea star. I can't wait to see what you're posting. I started a blog a year and a half ago (?) but I haven't posted anything in it.
