The new earthworms made quite an impression this week! We noticed right away that these worms are a lot bigger and you can see all of their parts more clearly. When they move, their heads become flat when they stretch!
Isopods are our last animal that we will be studying with this science unit and man o' man are they fascinating! here are some fun facts about these creatures
- Isopods are crustaceans. They are closely related to lobsters, crayfish, and crabs.
- Like crustaceans, their bodies have an exoskeleton made of overlapping plates. The isopods have 7 plates.
- Isopods get oxygen mostly from their gills. The gills must be moist for the isopods to breathe.
- Wood is their main food source. They seek a dark, moist environment.
- Sowbugs and pill bugs have a similar structure, with a few slight differences. Sowbugs antennae have 3 segments, while pill bugs have 2. The carapace (body) of the sowbug is flat and the pillbug is rounder and smoother.
