Spiny Squat Lobster

Overview

The Spiny Squat Lobster (Galathea strigosa) is a striking crustacean easily recognized by its vibrant red-orange body adorned with distinct, transverse electric-blue stripes. Often described as a cross between a crab and a lobster, it is one of the largest squat lobsters found within its range.

Appearance

This species features a dorsoventrally flattened body and a well-calcified carapace covered in fine hairs. Its most notable features are the long, robust front claws, which are heavily armed with spines and bristles, giving the animal a "furry" appearance. The rostrum is pointed with several sharp teeth along its edges, and the eyes are prominent and dark. Adults can reach a total length of up to 17–18 cm, including the claws.

Distribution & Habitat

Galathea strigosa is widely distributed throughout the northeast Atlantic Ocean, ranging from Norway down to the Canary Islands, and is also common in the Mediterranean Sea. It is a benthic species that prefers rocky or gravelly substrates, where it spends much of its time hiding in crevices, fissures, or under rocks. While it can be found in shallow sublittoral zones, it has been recorded at depths of up to 600 meters.

Biology & Behavior

Primarily nocturnal, this squat lobster remains concealed during the day to avoid predators. It is a scavenger that emerges at night to forage for detritus, small invertebrates, and organic matter. When threatened, it can perform rapid backward swimming by using its abdominal tail fan. Like other crustaceans, it must periodically molt its exoskeleton to grow.
