Caribbean Spiny Lobster (Panulirus argus)
Anatomy
Belonging to the arthropod phylum P. Argus has a segmented body design, a hard exoskeleton, jointed appendages and is an invertebrate. P. Argus is identifiable by their elongated cylindrical bodies with hard exoskeletons and forward facing spines which lend from the species' common name, Caribbean Spiny Lobster. P. Argus have biramous legs meaning that each leg branches off into two limbs and each branch attaches segments end to end ultimately terminating in a spiked point [1]. Each of the somites on the ventral side of the abdomen is outfitted with swimmerets. These small black and yellow legs are used primarily for swimming, brooding eggs, and catching food and redirecting it toward the mouth and are found on many other arthropods[2] 3. P. Argus large pinching claws found in other species of lobsters; however, they do possess a strong mandible that can crush mollusk shells for feedingCite error: Invalid <ref> tag; refs with no name must have content 4. In terms of sexual dimorphism males have a slightly wider sternum than females, unlike their male counterparts female sternums are striated[3] 2.
Biology
- Habitat: P. Argus are known to be found as in waters up to 100 meters deep as far north as the Outer banks of North Carolina and as far south as the coast of Brazil along the eastern coasts of North and South America. P Argus. can also be found throughout the Gulf of Mexico, the Bahamas, and the Caribbean[4] 2. Since they are a nocturnal species and the prey of many predators such as Octopi, Sharks, Snappers and Groupers, P. Argus tends to choose a habitat with substantial cover in order to protect itself. This explains why P. Argus is found in and around coral reefs, sea grass beds, beach piers, and under mangrove roots since these habitats allow for a sustainable food source for P. Argus as well as ample protection from predators[5] 4.
Threats
Other Names
A study conducted by Shane K. Sarver, et al. studied mtDNA sequences of P. Argus from the Caribbean and the Brazilian coast to determine the genetic diversity in Spiny Lobsters from both locations in order to find whether they were genetically isolated from one another. It was experimentally determined that there was enough DNA sequence diversity to warrant the naming of two subspecies one being Panulirus argus argus which is found north of the equator and in the Caribbean and the other being Panulirus argus westonii which is found south of the equator in Brazil[6] 5. Other common names for the Caribbean Spiny Lobster include Bermuda spiny lobster, common spiny lobster, Florida spiny lobster, West Indian langouste and West Indian spiny lobster. Most of these names are derived from the location of their habitats and the small changes in coloration and size that correlate with their different environments.
