spiny lobster


Panulirus versicolor, also called langouste, langustas, or rock lobsters, belongs to a family named Palinuridae of around 60 types of achelate crustaceans, in the Reptantia named Decapoda.

Painted spiny lobsters are additionally, particularly in New Zealand, Australia, Ireland, Bahamas, and South Africa, called ocean crayfish, crayfish or crawfish. These terms which somewhere else are saved for freshwater crawfish.

The hairy lobsters such as Palinurellus were beforehand isolated into their very own group, the Synaxidae, yet are generally viewed as individuals from the Palinuridae. The slipper lobsters named Scyllaridae, are their next-nearest relatives, and these a few families make up the Achelata.


Furthermore, the genera of painted spiny lobsters incorporate Palinurus and various re-arranged words thereof: Linuparus, Panulirus, and so forth. In all, 12 surviving genera are perceived, containing about 60 living species.

The history of Panulirus versicolor is given below:

Origin of Panulirus versicolor

Origin of Panulirus versicolor is Indo-pacific

Fossil record

Moreover, the fossil record of panulirus versicolor has been stretched out by the revelation in 1995 of a 110-million-year-old fossil close El Espiñal located in Chiapas, Mexico.

Laborers from the National Autonomous University of Mexico have named the fossil Palinurus palaecosi, and report that it is nearest to individuals from the genus Palinurus presently living off the shorelines of Africa.

Distinctive Features of Panulirus versicolor

In spite of the fact that they externally look like real lobsters as far as generally speaking of shape and having a hard exoskeleton and carapace, the two groups are not firmly related.

Spiny painted lobsters can be effortlessly recognized from genuine lobsters by their thick, long, spiky antennae, by the absence of chelae (paws) on the initial four sets of strolling legs, despite the fact that the females of most species have a little hook on the fifth set, and by an especially particular larval stage called phyllosoma.

Genuine lobsters have significantly littler claws and antennae on the initial three sets of legs, with the main being, especially developed.


Painted Spiny lobsters have commonly a compacted carapace, coming up short on any horizontal edges. Besides this, their antennae come up short on a scaphocerite, the smoothed exopod of the antennae.

This is combined with the epistome which is a plate between the basis of antennae and the labrum. Furthermore, the flagellum, at the top of the antennae is heavy, tapering and long. The wandering legs named pereopods end in chelae.


Numerous spiked lobsters make rasping sounds to repulse predators by rubbing the “plectrum” at the bottom of the spiky lobster’s antennae against a “file”. Furthermore, the sound is delivered by frictional vibrations- slipping and sticking, just like elastic materials sliding against hard surfaces.

Though various creepy crawlies utilize frictional vibration components to create sound, this specific acoustic mechanism is one of a kind in the set of all animals.

Altogether, the framework does not depend on the hardness of the exoskeleton, the same number of other arthropod sounds do, implying that the spiny lobsters can keep on delivering the deterrent sounds even in the period following a shed when they are generally powerless.

The stridulating organ is available in all lobsters except three genera in the family which are Projasus, Jasus, and the hairy lobster named Palinurellus. Its form can recognize distinctive species.


versicolor is found in the tropical shallow waters of the western Indian and the Pacific Ocean.

Besides this, it is found in the Indian Ocean and from as far south on the east bank of Africa as Natal, through the Persian Gulf and the Red Sea, in the Arabian Sea crosswise over to Myanmar, India, Malaysia, and Thailand down through Indonesia to north-western waters of Australia.

Furthermore, in the western Pacific, it exists as southern Japan, all through Micronesia, Polynesia, Melanesia, and in the waters of north-eastern Australia.


This is a typical animal group. It is harvested all through its range, yet is majorly for the local use only. It is gathered by high quality, recreational and business fishers dominatingly inside Kenya, New Guinea, Palau, India, and the Great Barrier Reef located in Australia.

Worldwide catches are nearly low contrasted with other Palinurid species at roughly 1,000 to 8,000 kg year-1 for each nation. Besides this, in India, this species just contains a little extent of the palinurid catch and is misused at low to direct levels.

Furthermore, business catches of this class were tested from 1969 to 1970 in Palau region. Although, the results demonstrated that the populace had experienced so little pressure and weight, therefore both the genders were similarly abundant.

Moreover, recruitment seems to happen throughout the entire year. In an investigation of Palinurid catch organization located in Sri Lanka, this species contained just 3% of the aggregate catch.

Population Drift

The population drift of painted rock lobster seems to be Stable.

Painted Rock Lobster Morphology

Panulirus versicolor grows up to 16 inches long, yet is commonly close to 12 inches. It has no paws, two spiked rostra over the eyes, and two sets of expansive antennae, similar to every single spiky lobster. The first pair of their antennae are twofold finished, the second spiny and hard, both are typically white.

Furthermore, the carapace is black, pink and white, with a reticule and horizontals stripes. The stomach area is green with transverse highly contrasting stripes. The legs are dark brown in color with white bands and the tail is bluish green in color.


Panulirus versicolor is found in zones of coral reef, frequently on the offshore edge of reef levels, where it uses the rocks and reef for shelter.

Furthermore, it is found in shallow waters, to a most extreme depth of 15 meters. Moreover, they are nighttime and they just total in little numbers.

Food Habits

Spiny lobsters feed on clams, sea snails, crabs, plants especially coralline algae, sea urchins, and dead creatures. On the other hand, they are eaten by sharks, octopuses and large fish.

The behavior of Panulirus versicolor

Panulirus versicolor is single and nocturnal. In the daytime, they hide away in little caves and hole in reefs or under coral at depths more than 49 ft. Besides this, they are carnivores. They eat both fresh got arthropods and carrion, different shellfish, and once in a while little fish.


Eggs are externally fertilized and are agonized under the stomach of a female. The larvae are discharged into the water segment once they are hatched.


Mating, usually happens during the summer season, only a couple of hours after the molting of developing female lobster while her shell is still delicate. The male, around the same size as of the female and with a genuinely hard shell, exchanges the sperm to the female’s sperm sac situated between the bottoms of the last two sets of legs.

This move is done in within 5 minutes. Moreover, the live sperm stays in the sac until the female sheds after 1 or more years later.

At that point, eggs are discharged through two little openings situated at the bases of the second set of strolling legs, are now fertilized as they pass over the sac of sperm, and are affixed to the swimmerets.

Furthermore, the egg-bearing or “berried” females convey the external eggs for about a year until the point when the embryos are completely developed and prepared to be hatched.

Lifecycle of Panulirus versicolor

The diverse types of Pacific Island lobsters have comparable life cycles. They have separate genders and, contingent upon species and area, achieve regenerative development at around 80 mm carapace length. They end up develop grown-ups within 3 to 5 years maximum and they live for around 10 years.

Numerous species seem to breed consistently, at times with a top in the hotter months of the year. Furthermore, a male stores a sperm bundle (spermatophore) at the bottom of a female.


Besides this, the female discharges a huge number of eggs which are then fertilized as they pass over the sperm parcel. Moreover, the prepared eggs are conveyed for about a month before they bring forth into little gliding stage.

These float in the ocean for a year or more and less than only one in each thousand makes due to settling on the ocean bottom as a youthful lobster (adolescent). Furthermore, a minimum of one in every hundred adolescents survives to wind up a develop grown-up.

Communication & Reception of Panulirus versicolor

Painted spiny lobsters communicate with each other by producing rasping sounds.


Spiny lobster growth maximum size of 14-16 inches of length.


Spiny lobster lives for about 10 years.
