Coenobita Compressus.

Coenobita Compressus, the second of the two most common species of land hermit crabs found in the U.S. of A, the first being Coenobita Clypeatus, is sometimes known as the Ecuadorian crab or the E crab. When in their juvenile state, they will often sport green or blue colours while their defence pincher (The larger of the two of their pinchers.) is tan. As they age, their colour can often be affected by their diet but a gray-ish or brown-ish colour is the most common colour, but it is not unheard of to find them sporting bright yellow, blue, or other colours
