The common lobster is classified as Least Concern (LC) on the IUCN Red List (1).
The common lobster is a very large and commercially important species (3). The upper surface is dark blue in colour with yellowish spots; the underside is more yellowish (3). The long abdomen terminates in a broad tail fan, and the first pair of walking legs, which are held forwards, are tipped with very large, formidable pincers. The pincers differ in size; one is used to cut prey, the other for crushing (4).
Lives in holes and tunnels on rocky substrata (2) from the lower shore to the sublittoral zone (4).
The common lobster is a scavenger, and uses its pincers to manipulate food items (4).
The sexes are separate, spawning occurs once a year in summer, and after mating, the female carries the eggs on her walking legs for around 9 months. The larvae are planktonic, and settle at around 3 weeks after hatching (4). Young lobsters are not often found, and very little is known of the behaviour of this stage, but it is believed that they live in coarse sediments and fine mud, where they construct burrows (4). Sexual maturity is reached at around 6 years of age; common lobsters are long-lived, and may live to over 15 years. Unfortunately, very few specimens reach such a ripe age, due to the pressures of intense fishing (4).
Numbers of the common lobster have been greatly depleted through overfishing; it is fished commercially using baited 'lobster pots'. As the lifecycle is not fully known, it is extremely difficult to sustainably manage the fishing of this species (5).
Specific conservation action has not been targeted at this species.
