Lobster-like

The division of living beings into systematics is a continuous subject of research. Different systematic classifications exist side by side and one after the other. The taxon treated here has become obsolete due to new research or is not part of the group systematics presented in the German-language Wikipedia.

Caribbean lobster ( Panulirus argus )

Parribacus antarcticus

The lobster-like (Palinura) were a suborder of the decapods (Decapoda). Because of their paraphyletic relationship, the families were incorporated into the sub-orders Achelata and Polychelida and the sub-order lobster-like dissolved.

description

They are large, elongated crabs, with a mostly flat carapace , with no or only a very small rostrum . The front legs are usually scissorless. In contrast, the last, fifth pair of striding legs often wears small scissors. The abdomen is strong and ends in a large tail fan, the rear edge of which is soft.

Most of the approx. 140 species are nocturnal and spend the day in caves and crevices. All lobsters feed on carrion , all kinds of invertebrates and algae. There are lobsters in all oceans. The 40 species of the Polychelidae family live in the deep sea up to a depth of 4500 meters. Many species are caught by humans and are considered delicacies.

Systematics

The langoustines were formerly divided into two superfamilies with five families:

• Lobsters (Palinura)
  • Eryonoidea De Haan, 1841
    • Eryonidae De Haan, 1841
    • Polychelidae Wood-Mason, 1874
  • Palinuroidea Latreille, 1802
    • Crawfish (Palinuridae) Latreille, 1802
    • Slippery shrimp (Scyllaridae) Latreille, 1825
    • Fur lobsters (Synaxidae) Bate, 1881

Lobsters and slippery lobsters were assigned to the suborder Achelata mainly because of the lack of claws on the first four pairs of striding legs and based on molecular genetic analysis . According to this analysis, the genera of the furry lobster are part of the lobster family and thus lose their family status. Polychelidae and Eryonidae became families of the Polychelida .
