To protect known breeding females, lobsters caught carrying eggs are to be notched on a tail flipper (second from the right, if the lobster is right-side up and the tail is fully extended). Following this, the female cannot be kept or sold, and is commonly referred to as a "punch-tail" or as "v-notched".
The lobster life cycle begins with an adult, hard-shelled male, about five to seven years of age, mates with a newly-mounted female. After egg spawning, a female lobster will carry the eggs ...
After mating, the fertilized eggs are carried on the female's pleopods until they hatch, with between 120,000 and 680,000 carried by a single female. [6] The eggs begin coral red, but darken as they develop to a deep maroon. [5] When she is carrying the eggs, the female is said to be "berried". The eggs are ready to hatch after 10 weeks, [6 ...
On this European lobster, the right claw (on the left side of the image) is the crusher and the left claw is the cutter.. Homarus gammarus is a large crustacean, with a body length up to 60 centimetres (24 in) and weighing up to 5–6 kilograms (11–13 lb), although the lobsters caught in lobster pots are usually 23–38 cm (9–15 in) long and weigh 0.7–2.2 kg (1.5–4.9 lb).

After mating, the fertilized eggs of the California spiny lobster are carried on the female's pleopods until they hatch, with between 120,000 and 680,000 carried by a single female. [50] The eggs begin coral red, but darken as they develop to a deep maroon. [51] When she is carrying the eggs, the female is said to be "berried".
After mating, the female carries the eggs on her abdomen held under her tail. When ready to release the eggs, she migrates to the reef crest and their release is usually followed by moulting. The larvae have a very long developmental period and are planktonic at first, before becoming "pueruli" larvae , a transitional phase between planktonic ...
The adult female consists of three parts, the cephalothorax, a thorax bearing two large lateral expansions or wings, and the abdomen which is responsible for carrying two oval egg-sacs. The female Nicothoe astaci abdomen tip measures 1.2–1.3 millimetres (0.047–0.051 in), and each wing measures 4 mm (0.16 in) long.
Panulirus argus, the Caribbean spiny lobster, [2] ... Like most decapods, P. argus hatches from eggs carried externally by the female for around four weeks. [3]
