A worldwide community photographing and learning about wildlife
These green to red or purple crabs with black stripes are active during daylight hours. They are so well adapted to living out of water that they spend at least half of the time that way. They have excellent eyesight which adapts well to both day and night. For the most part, these crabs feed on land on diatoms and algae. Occasionally they will prey on hermit crabs and Black Turban snails, and they’ve even been observed capturing kelp flies with their very dexterous claws.
