European Lobster

Overview

The European lobster (Homarus gammarus) is a large, clawed crustacean native to the eastern Atlantic Ocean, the Mediterranean Sea, and parts of the Black Sea. Known for its deep blue coloration, this species is a highly valued marine inhabitant that plays a significant role as an active predator in its ecosystem.

Distribution & habitat

This species is found along European coasts, ranging from Norway and the Shetland Isles south to Morocco, as well as throughout the Mediterranean and Black Seas. They prefer rocky seabeds, where they occupy crevices, caves, and excavated tunnels that provide essential shelter.

Appearance

Adults are typically deep blue, sometimes appearing nearly black, with lighter, yellowish tones on the underside of their claws. They possess a rigid, segmented exoskeleton and five pairs of legs. The most distinctive features are the two large, unequal claws: one is specialized for crushing, while the other is adapted for cutting.

Biology & behavior

European lobsters are solitary and highly territorial, often aggressively defending their chosen shelters. They are primarily nocturnal, emerging from their burrows at night to navigate the seafloor using their long antennae. As they grow, they must periodically shed their hard exoskeleton through molting.

Feeding

Progressing from opportunistic larvae to active hunters, adults act as formidable predators and scavengers. Their diet consists of a variety of marine life, including fish, crabs, mollusks, and other shellfish, which they subdue and tear apart using their powerful claws.

Reproduction

Mating typically occurs during the summer months. After fertilization, females carry thousands of eggs beneath their tails for up to a year. Once the eggs hatch, the larvae lead a free-floating, planktonic existence before eventually settling on the seabed to begin their benthic life.
