Toddler Blog – Fiddler Crabs


13th March 2019

Today we discovered all about the fantastic world of the fiddler crab! First, we practiced our animal sign language then we learnt about the different parts of a crab’s body and looked to see what makes fiddler crabs different to other crabs we find in the ocean. We made our own fiddler crabs out of paper, decorated them with upcycled paper scraps and used split pins to make their big claws wave, just like they do in real life! Next, we went on a crab spotting safari in our Plymouth Sound exhibit where we peered into rockpools to find edible crabs, hermit crabs and shore crabs! Then we went back to the café for story time, sang our special song all about mangroves and had a crab-tastic dance party!

Who is it?

Fiddler crabs live in mangrove forests, they dig themselves lovely little holes to live in and scurry about in between the roots of the trees. They are very small crabs, the largest species in the world is only the size of a grown up’s thumb!

What makes it special?

Male fiddler crabs look very strange! They have one claw which is tiny and one claw which is ginormous! Sometime this claw is bigger than their body, imagine if your hand was the size of your whole body! Wouldn’t that be weird? They use their claws to talk to each other, just like when we wave to our friends.

How can we look after them?

Unfortunately, many mangrove forests where fiddler crabs live are in trouble! They are being cut down to make space for farms and houses. There are lots of people out there replanting mangrove forests just like they are with the rainforests. We can help mangroves by letting people know just how important they are!

Next Week: We are learning about the lovely lemon shark!
