Crabs fall into the category of crustaceans. These creatures of the deep can range in sizes from the tip of your finger to the size of your body! Feared and enjoyed by so many, these animals have adapted extremely well for their environment.

Crustaceans have a hard exoskeleton. This skeleton is made of the same material in your finger nails called chitin. Hidden in their thorax is actually a tail! This tail was thought to shorten over hundreds of years of evolution. Within their stomach crabs have teeth that crush their food into a pulp for digestion.

So if you are every enjoying a crab, admire their evolutionary features that have made them such a diverse species in the deep around the world.

Sea Stars

Starfish or sea stars are one of the creatures of the deep, crawling over rocks and sand to get to where they need to be. These creatures sometimes don’t even seem to be alive.

With there hundreds of feet under one of their five legs, these creatures are able to to move in any direction. Not only do these feet help in movement but, they are also used to direct food into the mouth of the sea star which is located in the centre.

One of the coolest things about sea stars is how they are able to reproduce. They can reproduce sexually or asexually. By just cutting off one of the arms of the organism, it will grow into a completely independent and new sea star with the exact same genes.
