Decapoda
Sign in to saveA decapod is a crustacean in the large order of Decapoda (from Ancient Greek δεκάς (dekás), meaning "ten", and πούς (poús), meaning "foot"), within the class Malacostraca, including crabs, lobsters, crayfish, shrimp, and prawns. Most decapods are scavengers. The order is estimated to contain nearly 15,000 extant species in around 2,700 genera, with around 3,300 fossil species. Nearly half of these species are crabs, with the shrimp (about 3,000 species) and Anomura including hermit crabs, king crabs, porcelain crabs, squat lobsters (about 2500 species) making up the bulk of the remainder.

OverviewAI-generated
Decapoda is an order within the class Malacostraca and phylum Arthropoda, belonging to the kingdom Animalia. The taxon, commonly known as decapods, was established by Latreille in 1802 and holds an accepted status in biological classification. These organisms inhabit marine, brackish, and freshwater environments.
The order has been documented in 14,611,993 occurrences globally. In the United States, 37,217 records are held by institutions including USNM, LACM, and UWBM, accompanied by 3,599 media files. Additionally, 28,239 PubMed entries reference the subject, while 3,270 other encyclopedia articles cite Decapoda.

Τα Δεκάποδα είναι τάξη καρκινοειδών εντός της ομοταξίας Μαλακόστρακα. Περιλαμβάνει τα καβούρια, τους αστακούς, τις γαρίδες και τις καραβίδες. Εκτιμάται ότι περιλαμβάνει 15.000 είδη σε περίπου 2.700 γένη, και έχουν βρεθεί 3.300 απολιθωμένα είδη. Σχεδόν τα μισά από αυτά τα είδη είναι καβούρια, ενώ από τα υπόλοιπα οι μεγαλύτερες ομάδες είναι οι γαρίδες και τα ανόμουρα (όπως οι ερημίτες κάβουρες). Το παλαιότερο απολιθωμένο δεκάποδο είναι ο Παλαιοπαλαιμόν, από το Δεβόνιο. Όπως υπονοεί και το όνομά τους, όλα τα δεκάποδα έχουν δέκα πόδια, με τη μορφή πέντε ζευγών θωρακικών εξαρτημάτων στα πέντε τελευταία θωρακικά τμήματα. Τα μπροστινά τρία λειτουργούν ως τμήματα του στόματος και γενικά αναφέρονται ως γναθόποδα, τα υπόλοιπα είναι τα περειόποδα. Σε πολλά δεκάποδα, το πρώτο ζεύγος φέρει μεγάλες δαγκάνες. Άλλα εξαρτήματα υπάρχουν στην κοιλιά, με κάθε τμήμα να μπορεί να φέρει ένα ζεύγος πλεόποδων, με τα δύο τελευταία να αποτελούν το ουριαίο πτερύγιο (μαζί με το τέλσον) και αποκαλούνται ουρόποδα.
