Quiz Answer Key and Fun Facts

1. Can hermit crabs be bred in captivity?

Answer: Only with tide simulation

Hermit crabs are difficult to breed in captivity because they need natural ocean currents to be simulated, and plankton for the young to feed on.

2. What is the proper way to hold a hermit crab?

Answer: On a flat palm

While hermit crabs can pinch, it is difficult for them to grab hold of flesh on a flat palm. Beware, they can scuttle very fast and fall!

3. A hermit crab out of its shell most resembles what?

Answer: A lobster

A hermit crab looks very much like a small lobster, except their tails are curved to hold the inside of their "borrowed" shell, and are not covered by shell (fleshy).

4. A hermit crab in the wild feeds on...

Answer: All of these

Wild hermit crabs have a huge variety of things they will eat. Some other things include worms and fish eggs.

5. In which scientific subphylum do hermit crabs belong?

Answer: Crustacea

While many people think hermit crabs look like spiders, they actually have very few similarities.

6. What is the pincer sometimes called?

Answer: Cheliped

The two front claws are not used for locomotion. The larger is used for defense while the smaller is used to bring food to the mouth.

7. Including the pincers, how many legs do hermit crabs have?

Answer: 10

The hind 2 pairs of a hermit crab's legs are usually inside the shell, used for grasping the borrowed shell.

8. Do hermit crabs have a shell that covers their whole body?

Answer: No

Actually, hermit crabs do have a shell of sorts, better known as a carapace. The back of their bodies, the tail area, is the only area that does not have full protection, making them require borrowed shells for complete coverage. Besides, a whelk shell (hermit crab's preferred type) is much harder than their natural shell, and provides greater protection.

9. What do anemones do to hermit crabs?

Answer: Live on their shells

The hermit crab provide locomotion for the anemones, and the anemones offer protection in the form of stings and camouflage.
Many hermit crabs will actually tend "gardens" of anemones, moving them from shell to shell as the hermit crab grows out of old ones.

10. What should a captive hermit crab's food be served in?

Answer: Shell

It is said that shell food containers offer some calcium to the crab's diet.
