What is the order family and genus of the star fish?

Answer 1

The biological classification (Linnaean taxonomy) of a star fish or sea star is as follows:

Kingdom=Animalia

Phylum=Echinodermata

Class=Asteroidea

The over 1700 different species of sea stars (star fish) are then divided into seven different orders which are themselves divided into families and then genera (plural of genus):

Order=Brisingida (contains 6 families and 17 genera) or

Forcipulatida (contains 6 families and 68 genera) or

Notomyotida (contains 1 family and 12 genera) or

Paxillocida (contains 5 families and 46 genera) or

Spinulosida (contains 1 family and 9 genera) or

Valvatida (contains 14 families and 165 genera) or

Velatida (contains 5 families and 25 genera)

Of these, Valvatida is the most diverse with nearly 700 different species. Some of the designations of family and genus are controversial, new research is always being published, and sometimes even new animals are discovered. Therefore these numbers are subject to change as new and better information becomes available.

Answer 2

Starfish belong to the order Asteroidea, the family Asteriidae, and the genus Asterias.
