Homarus americanus (Amérique) / Homarus vulgaris (Europe)
How do you tell the difference between male and female lobsters? The first pair of swimming legs (called 'swimmerets') near the thorax are large and hard in the male, and small and soft (like the other swimmerets) in the female. The female also has a wider tail compared to a comparably-sized male. She requires this additional width to transport her eggs.
The shell of the Breton lobster (a large crustacean that can reach 45 or 50 cm in length) is bluish-green and includes some lighter patches. The pincers are highly developed and very strong. The body of the animal ends in a fan-shaped fin. The female lays between six and ten thousand tiny eggs which she keeps under her body and which hatch into little larvae, many of which are devoured by various animals. The lobster fishing season goes from late May until September.
