Body Struture
A Red Face Hermit Crab is very small and is normally found in its shell. On rare occasions, this miniature crab will come out of its shell, crawling around on its walking legs.
Inside Shell:
The hermit crab uses his walking legs that are outside of its shell to walk on land. In the ocean, it crawls on the ground with its walking legs as well.

Outside Shell:
This miniature crab uses all of its walking legs once fully out of its shell.
Unlike others of its species, a Red Face Hermit Crab can be found worldwide. This means it can be found in any climate, whether it is in the freezing artic or in burning deserts. The Red Face Hermit Crab comes out of its shell occassionally to cool down in warmer climates, but otherwise it will have its shell on.
Food Chain
There are many things that like to munch on this defensless creature including sea birds, fish, octopuses, and other fellow crabs. This crab doesn't eat much besides dead plants and animals.
State of Existence
The Red Face Hermit Crab is not very important to humans due to its size. It doesn't pose a threat to any sea creatures, either. In most ecosystems, these crabs are very common since it is found world wide which proves that they aren't threatened by humans. Pretty much the only thing this small crab provides to humans are miniature shells we can keep in rememberance.
Cool Facts
A male's reproductive organ is found under the crab's heart and is by its last pair of walking legs. A female's is located at the base of its middle walking legs. Depending on the crab's size, you could get large amounts of new miniature crabs.
Gets prey:
Their process of finding prey isn't very fascinating due to the fact that they only feast on dead plants and animals. I guess this is an adaptation they have had to learn because of their size.
Importance in the ocean:
These crabs eat dead animals which prevents them from decaying at the bottom of the ocean floor. This prevents all of its fellow sea creatures from breathing toxic gases from decaying fish.
Since they devour on dead bodies, this means they live in the deep zone. That is the part of the ocean under 1,000 meters.
Even though it is very rare, some have glass shells. Those shells are very unique and expose its complex body. Also, it is the smallest of the hermit crabs which means it won't be a filling meal.

In the artic
Red Face Hermit Crabs are obviously related to all hermit crabs. They are closely related to Scarlet Hermit Crabs, Scarlet Reef Hermit Crabs, Dwarf Red Tip Hermit Crabs, and many more. All of these crabs can be broadly classified as Crustaceans.
