My organism is the hermit crab. The hermit crab is famous for being a popular pet because it is inexpensive and easy to care for. Also, they tend to live a long time, having a maximum life span of 15 years, and can grow to be as big as 40 cm. Another interesting fact about hermit crabs is that in order to get oxygen, they pick up water with its claws and deposit it into its gills, where they then filter out the oxygen. Lastly, when a hermit crab molts, it will often consume its own skin for nutrients.
