The Forcipulatida are an order of sea stars, containing three families and 49 genera.
Description
Forcipulatids share with the brisingid sea stars distinctive pedicellariae, consisting of a short stalk with three skeletal ossicles. Unlike that group, however, the forcipulatids tend to have more robust bodies.[1] The order includes some well-known species, such as the common starfish, Asterias rubens.
Phylogeny
The order is divided into three families:[2]
- Family Asteriidae — 39 genera
- Family Heliasteridae — two genera
- Family Zoroasteridae — eight genera
World Register of Marine Species gives another taxonomy:
- Family Asteriidae Gray, 1840
- Family Heliasteridae Viguier, 1878
- Family Pedicellasteridae Perrier, 1884
- Family Pycnopodiidae Fisher, 1928
- Family Stichasteridae
- Family Zoroasteridae Sladen, 1889
