Scientific Name: Dardanus megistos
Common Name: Red hairy hermit crab

Size: Up to 20 cm including legs
Depth Range: 1 – 50 m
Habitat: Sandy bottoms, coral rubble areas, and reef slopes; usually seen carrying a large gastropod shell
Diet: Omnivorous scavenger—feeds on detritus, algae, small invertebrates, and carrion
Reproduction: Separate sexes; females carry eggs in their abdomen until they hatch into planktonic larvae
Fun Fact: This species often hosts symbiotic sea anemones on its shell, which provide protection with their stinging tentacles while benefiting from the crab’s mobility and food scraps.

Observation Tip: Look for their distinctive red and white coloration and large, hairy claws. They are often active at night but may be spotted during the day moving slowly across the seabed.
