decorator crab

MEDIUM
Family
Majidae
Also known as
spider crab, masking crab
Description
Decorator crabs are members of the family Majidae that camouflage themselves by attaching bits of sponge, algae, and other organic material to hooked setae (hairs) on their carapace. This individual appears heavily decorated with red sponge fragments and is nestled among anemone or soft coral tentacles. They are omnivores, feeding on detritus, algae, and small invertebrates.
Habitat
Found on coral reefs and rocky substrates worldwide, typically in tropical and subtropical waters from shallow reefs down to moderate depths. Commonly associated with corals, sponges, and anemones where their camouflage is most effective.
Conservation status
Least Concern
Notes
The crab is extremely well camouflaged with attached red sponge and algal material, making precise species identification impossible. Two distinctive stalked eyes with granulated corneas are visible. The crab appears to be perched between what appear to be anemone tentacles (bubble-tip or similar). The macro photograph is well-focused on the subject. Species-level ID within Majidae not possible from this image.
