Crustacean

Identification & Biology

• IdentificationA colourful squat lobster with a bright red body marked with vivid blue streaks and lines across the carapace and claws. Long, spiny front claws are held out in front. The abdomen is tucked underneath the body. Not a true lobster but a close relative of hermit crabs.
• SizeBody length up to 5 cm (excluding claws). Claw span can double the apparent size.
• Social HabitSolitary or in small groups. Found tucked into crevices and under boulders. Retreats rapidly backward when disturbed.
• HabitatRocky reefs, boulder undersides, caves, and crevices. Prefers dark, sheltered spaces.
• Depth0 to 60 m. Common in the shallows to about 30 m.
• Feeds OnSuspended organic particles, detritus, and small invertebrates. Filter feeds and scavenges.
• DistributionEastern Atlantic from Norway to the Azores, and throughout the Mediterranean Sea. Common in Maltese waters.
• DescriptionGalathea strigosa is one of the most colourful crustaceans on Mediterranean reefs, its striking red and blue pattern making it a favourite subject for macro photographers. Despite its name, it is not a true lobster but belongs to a group more closely related to hermit crabs. Look for it in dark crevices and under overhangs, where its blue markings often catch the torchlight.
