Panulirus marginatus, the Hawaiian spiny lobster, is a species of spiny lobster in the family Palinuridae which is endemic to the Hawaiian Islands. [2] It is the subject of extensive commercial and recreational fisheries. [2]

The species can reach a total body length of about 40 cm with their carapace length reaching about 12 cm [4] . They have an exoskeleton that encases them and protects them from predators. This exoskeleton is molted periodically as the lobster grows and ages. Shortly after molting the lobsters are in a more vulnerable state and therefore go deep into their hiding so that they can be safer until their carapace hardens once again. Spiny Lobsters do not have the large claws like some other lobster species.
This species is endemic to the Hawaiian Islands. Ranging from the Hawaiian Islands to the Northwest where the Pearl and Hermes Atoll is. They have also been found around Laysan Island. They are usually found in shallow waters but have been found up to 143m beneath the surface [4] . They are nocturnal and known to hide in protected spaces under rocks and in crevices.
They have always been used as a food source. They are easy to find and catch due to often being found in shallow waters, however they are now a protected species in Hawaii and therefore guarded by specific laws to preserve their population. No Spiny Lobsters may be caught between May-August and no females with eggs may be taken. The minimum legal size to take when all other stipulations have been met is a carapace 3.25 inches in length. [5]
The species was historically used in place of pigs during sacrificial offerings to gods. [5]
Spiny lobsters, also known as langustas, langouste, or rock lobsters, are a family (Palinuridae) of about 60 species of achelate crustaceans, in the Decapoda Reptantia. Spiny lobsters are also, especially in Australia, New Zealand, Ireland, South Africa, and The Bahamas, called crayfish, sea crayfish, or crawfish, terms which elsewhere are reserved for freshwater crayfish.
The California spiny lobster is a species of spiny lobster found in the eastern Pacific Ocean from Monterey Bay, California, to the Gulf of Tehuantepec, Mexico. It typically grows to a length of 30 cm (12 in) and is a reddish-brown color with stripes along the legs, and has a pair of enlarged antennae but no claws. The interrupted grooves across the tail are characteristic for the species.
Jasus edwardsii, the southern rock lobster, red rock lobster, or spiny rock lobster, is a species of spiny lobster found throughout coastal waters of southern Australia and New Zealand including the Chatham Islands. This species is commonly called crayfish or crays in both Australia and New Zealand and kōura in Māori. They resemble lobsters, but lack the large characteristic pincers on the first pair of walking legs.
Lobsters are widely fished around the world for their meat. They are often hard to catch in large numbers, but their large size can make them a profitable catch. Although the majority of the targeted species are tropical, the majority of the global catch is in temperate waters.
Panulirus cygnus is a species of spiny lobster, found off the west coast of Australia. Panulirus cygnus is the basis of Australia's most valuable fishery, making up 20% of value of Australia's total fishing industry, and is identified as the western rock lobster.
Halocaridina rubra, the Hawaiian red shrimp or volcano shrimp is a small red shrimp of the family Atyidae, with the common Hawaiian name ʻōpaeʻula.
Panulirus argus, the Caribbean spiny lobster, is a species of spiny lobster that lives on reefs and in mangrove swamps in the western Atlantic Ocean.
Panulirus versicolor is a species of spiny lobster that lives in tropical reefs in the Indo-Pacific. Other names include painted rock lobster, common rock lobster, bamboo lobster, blue lobster, and blue spiny lobster. P. versicolor is one of the three most common varieties of spiny lobster in Sri Lanka, alongside Panulirus homarus and Panulirus ornatus.
Panulirus pascuensis is a species of spiny lobster found around Easter Island and the Pitcairn Islands in the Pacific Ocean. It is known in English as the Easter Island spiny lobster and in Spanish as Langosta de Isla de Pascua. This lobster is fished on a small scale for local consumption.
Panulirus homarus is a species of spiny lobster that lives along the coasts of the Indian and Pacific Oceans. It lives in shallow water, and feeds on the brown mussel Perna perna. It typically grows to a length of 20–25 cm (7.9–9.8 in). Alongside the dark green nominate subspecies, two red subspecies are recognised, one around the Arabian Peninsula, and one around southern Africa. It is the subject of small-scale fishery.
Panulirus brunneiflagellum is a species of spiny lobster that lives around the Ogasawara Group of southern Japan. Its members were previously included in P. japonicus, although it may be more closely related to P. femoristriga. It has been fished for more than 150 years by Japanese fishermen, who call the species aka-ebi. It differs from related species by the lack of banding along the flagella of the first pair of antennae.
Panulirus ornatus is a large edible spiny lobster with 11 larval stages that has been successfully bred in captivity.
Loxorhynchus grandis, commonly known as the sheep crab or spider crab, is a species of crab in the family Epialtidae. It is the largest crab found on the California coast. The species was first described to science by William Stimpson in 1857. The type specimen was collected on the coast of California, near San Francisco. Fossils from the late Miocene epoch indicate that this species is at least 11.63 to 5.333 million years old.
Scyllarides squammosus is a species of slipper lobster known as the 'blunt slipper lobster. It is found throughout the Indo-West Pacific region. Specifically its range is from Australia, Japan, Hawaii, Melanesia, New Caledonia to East Africa. Scyllarides squammosus has been found at depths from 7.5 m to 71 m.
Panulirus guttatus, the spotted spiny lobster or Guinea chick lobster, is a species of spiny lobster that lives on shallow rocky reefs in the tropical West Atlantic and Caribbean Sea.
Panulirus echinatus, the brown spiny lobster, is a species of spiny lobster that lives on rocky reefs in the tropical western Atlantic Ocean and central Atlantic Islands.
Jasus paulensis, also commonly known as the St Paul rock lobster, is a species of spiny lobster found in the waters around Saint Paul Island in the southern Indian Ocean and around Tristan da Cunha in the southern Atlantic Ocean. At one time the rock lobsters on Tristan da Cunha were believed to be a separate species known as the Tristan rock lobster, but the use of mitochondrial DNA sequencing has shown them to be identical. Some authorities, for example the International Union for Conservation of Nature, retain them as separate species. The Tristan rock lobster features on the coat of arms and the flag of Tristan da Cunha.
Panulirus longipes, the longlegged spiny lobster, is a species of spiny lobster that lives on shallow rocky and coral reefs in the tropical Indo-Pacific region. The International Union for Conservation of Nature has assessed its conservation status as being of "least concern".
Panulirus penicillatus is a species of spiny lobster that lives on shallow rocky and coral reefs in the tropical Indo-Pacific region. Common names for this spiny lobster include variegated crayfish, tufted spiny lobster, spiny lobster, Socorro spiny lobster, red lobster, pronghorn spiny lobster, golden rock lobster, double spined rock lobster and coral cray. It has a very wide range and the International Union for Conservation of Nature has assessed its conservation status as being of "least concern".
Panulirus polyphagus, the mud spiny lobster, is a species of crustacean that lives on shallow rocky reefs and muddy substrates in the tropical Indo-Pacific region. The International Union for Conservation of Nature has assessed its conservation status as being of "least concern".
