Lobsters

One of the marine animals that people associate the most with the Maritimes is the lobster (Homarus americanus).  While they are a tasty meal (dipped in melted butter!) they are also a very interesting animal that comes in a variety of colours and sizes, many of which can be found at the Huntsman’s Fundy Discovery Aquarium.  Recently, I read a fascinating book called The Secret Life of Lobsters by Trevor Corson.  I would recommend it to anyone who is interested in lobster biology or just lobsters in general.  

Lobster info:
·         Lobsters can be right or left handed depending on which side the crusher claw is on.
·         Lobsters can regenerate lost legs, claws and antennae but not eyes.
·         A commercial size lobster is about 7-8 years old.
·         A female needs to be soft (just moulted) to mate.
·         After moulting a lobster will consume some of its old shell to take in calcium to harden its new shell.

...no, we can't keep them! :)

A rare "yellow" lobster...1 in 30 million.

After moulting the lobster has been nibbling away at its old exoskeleton (shell).

Notice the soft new leg growing.
