This week, in our invertebrates class, we covered Arthropods. In case you're not familiar with them, this group includes popular species, such as crabs and lobsters, and less popular species like spiders and scorpions. After four hours of lecture we headed to the lab to dissect lobsters and identify their internal bits. We froze them ahead of time so that they wouldn't suffer through the process and then started cutting them open. We identified brains, hearts, digestive systems, and a host of other important organs.
We were a bit too queasy to eat them afterwards and we kind of butchered the yummier parts in our dissection anyway, but the crabs in the visitor touch tanks were quite happy to help us dispose of what was left of the each lobster.
