#413: Nantucket Harbor Crabs

The Maria Mitchell Association Aquarium
does Marine Ecology Field trips in the summer.
First, the interns pull a seine net through the water:
 Then we quickly pick everything off the net
with cries of wonderment
(a baby flounder! A tiny blowfish! What’s this???)
And sort it all into buckets.
Next, the interns tell us about our finds:
Here’s a crab

Here’s her egg mass. Cool.
 Here’s a blue claw crab. 
You never see them with this much seaweed.
Usually they shed their shell, that’s what
we eat as ‘soft shell crabs’.
They have this defense mechanism where if they feel 
threatened they can detach a claw then grow a new one.
