Judah and Tilly are loving their Marine Biology class this year…especially dissecting a dog fish.
Judah, age 12
Homeschool Marine Biology
Judah and Tilly’s Marine Biology class involves several hands on project weeks. In discussing what they could do, they decided to dissect….a shark. This was all fine and good. I ordered the shark. Had it shipped to our church (because the company wouldn’t ship it to a residential address) and purchased the necessary supplies (gloves, scalpels). The problem is the time between deciding on the project and beginning it…I became pregnant.
Dissection and Morning Sickness Do Not Mix
I do not have a week stomach. I dissected my share of animals during school. But when I am pregnant…well, things are different. Having my living room filled with the odor of formaldehyde and watching my children slice into the shark flesh…well, it’s not working out so well.
Identifying the Anatomy of a Dog Fish
I sat all the way across the room and read the directions to Judah and Tilly….and we’re not finished. This project is going to take a while.
I was very impressed at their knowledge though. Judah was able to identify the shark as male within about two minutes of unwrapping it. He could see the difference in the fins.
Did you know the spiny dogfish shark does not reach reproductive maturity until 11 years (for the male) and 19 for the female?
Wish me luck, and we continue to work on this project together!
