Scaly Slipper Lobster

Overview

The Scaly Slipper Lobster (Scyllarides squammosus) is a distinctive, clawless crustacean widely distributed across the Indo-West Pacific region. Known for its flattened body and specialized, shovel-like antennae, this species is primarily nocturnal and remains well-hidden in rocky crevices or coral reef cavities during the day.

Distribution & habitat

This species is found throughout the Indo-West Pacific, ranging from East Africa and the Red Sea to Japan, Australia, and Hawaii. They typically inhabit rocky and coral reef environments, often seeking shelter in dark holes, caves, or under ledges at depths ranging from approximately 5 to 120 meters.

Appearance

The Scaly Slipper Lobster features a robust, flattened carapace covered in short hairs and tubercles, providing effective camouflage against reef substrates. Its coloration is generally a light reddish-brown mixed with yellow, often accented by purple on the leg joints and orange-dotted eyes. A key identifying feature is the first abdominal segment, which typically displays a light yellow pattern with three circular brown marks. Like other slipper lobsters, its second pair of antennae are modified into broad, plate-like structures used for sensing the environment.

Biology & behavior

These lobsters are shy, nocturnal animals that are rarely seen during daylight hours. When threatened, they can retreat rapidly into crevices or swim backward by forcefully flapping their tails. As crustaceans, they undergo periodic molting to grow, and their shells may often accumulate algal growth depending on the time elapsed since their last molt.

Feeding

As nocturnal foragers, they feed on a variety of benthic prey, including mollusks, shrimp, crabs, worms, and sea urchins. They use their powerful legs to manipulate or pull apart their prey.
