Tuesday we went back to the Adventure Lab to meet our Fiddler Crabs. Each student received their own crab to observe.
They noticed that the crab's carapace was typically a dark brown.
They saw little feeler hairs on the crab's legs.
They learned that the crabs can only move from side-to-side.
A few other things they learned were:
Fiddler Crabs molt by their exoskeleton softening enough to grow
Fiddler Crabs have gills to help them breathe under water
Male Fiddler Crabs have one large chelae and one small chelae
Female Fiddler Crabs have two small chelae
They have two eye stalks on their cephalathorax
