Description
The land hermit crab species Coenobita purpureus, also referred to as the Okinawan blueberry hermit crab or blueberry hermit crab, belongs to the Coenobitidae family. Although they are white as juvenile crabs, they are typically purple, blue, purple-blue, or purple-red in colour. Their eyes are oval in shape, and their eyestalks are long. Their abdomen is short and fatty, and the pincer joints and walking legs are yellow.
Bulky hermit crab that appears to have been put together from pieces of other species. When young, they are white and cream in colour (sometimes brown), eventually changing as they become older to a vibrant blue and purple hue. Eyes that are big and dazzling in black.
Distribution
They mainly live and are native to the shores of Japan’s continental islands, oceanic islands, and mainland. They are thought to have a fairly limited geographic range in this part of the northwest Pacific.
Behavior
Mostly nocturnal. The brightly colored laundry bottle cap or plastic container that washed up on the shore after a storm will certainly cause blueberries to “throw down” or engage in combat because they are fiercely territorial. They have a reputation for being demanding and aggressive towards other crabs when they want anything.
Keeping as Pet
A 5-gallon tank might be used. Remember that they need two dishes with water—one with freshwater and one with salt—that are deep enough for them to submerge themselves.
75 to 85 degrees are the temperatures.
70% humidity or greater is considered safe for air.
