The main difference between asteroids and ophiuroids is the way that the rays, or arms, attach to the body. In ophiuroids, the arms are not joined to each other and the body and arms are clearly separated, but in the asteroids the arms are joined to each other and the boundary between arms and the central disc is blurred.

Starfish is a group larger than a family it is a class. To determine which family you want you will have to get a lot more specific in your question.Superregnum: EukaryotaRegnum: AnimaliaSubregnum: EumetazoaSuperphylum: DeuterostomiaPhylum: EchinodermataSubphylum: EleutherozoaSuperclassis: AsterozoaClassis: AsteroideaOrdines: Brisingida - Forcipulatida - Notomyotida - Paxillosida - Peripoda - Platyasterida - Spinulosida - Valvatida
Ophiuroids are carnivores, filter feeders, and scavengers; those of some species use more then one method to obtain food. Mucus on the tube feet can trap phytoplankton, bacteria, and even medusae from the water or particles from sediment that are moved by the tube feet to the mouth; some ophiuroids capture small crustaceans or worms by looping the organisms with their rays. The mouth is surrounded by five jaws and leads to an esophagus that connects to the sac-like stomach. The stomach fills much of the disc, but does not extend into the arms, and ends blindly (that is, it has no anus). Digestion occurs within 10 pouches or infolds of the stomach.
The correct term is a Sea Star. The sea star bearing [up to] nine arms is called a "fragile star" and is also a close relative to the "sunflower star".
The Kingdom of a brittle star is Animalia, the Phylum is Echinodermata, the Class is Ophiuroidea, the Order is Ophiurida, the Family is Ophiuridae, the Genus can vary but examples include Ophioderma or Ophiomyxa, and the Species can also vary, such as Ophioderma brevispinum or Ophiomyxa flaccida.

A example of an ophiuroidea is a sea star or a star fish. They are part of the five different echinoderm groups: Crinoidea, Asteroidea, Ophiuroidea, Echinoidea, Holothuroidea.
Phyla: Echinoderms Class: -Asteroidea - Sea stars -Ophiuroidea - Brittle stars -Holothoridea- Sea cucumbers
These are the classes of Echinoderms:1.Asteroidea - star fish, sea stars2.Ophiuroidea - brittle stars3.Echinoidea - sea urchins4.Crinoidea - feather stars5.Holothuroidea - sea cucumbers
Echinoderms are a phylum of marine animals. I dont know what is ment by 'the three types' as there are 5 living classes : Crinoidea (Sea lilies), Asteroidea (starfish), Ophiuroidea (brittle stars ), Echinoidea (sea urchins and sand dollars) and Holothuroidea (sea cucumbers). The most commonly observed being Asteroidea, Echinodea and Holothuroide as Crinoidea are generally benthic sessile creatures and most Ophiuroidea are benthic and photophobic so even the littoral ones are rarely seen during the day,
The 5 living classes of echinoderms are Asteroidea (sea stars) Crinoidea (sea lillies) Echinoidea (sea urchins and sand dollars) Holothuroidea (sea cucumbers) Ophiuroidea (brittle stars and basket stars)
The difference is 4
The classes present in subphylum Eleutherozoa include Asteroidea (sea stars), Ophiuroidea (brittle stars), Echinoidea (sea urchins and sand dollars), Crinoidea (sea lilies and feather stars), and Holothuroidea (sea cucumbers).
The only Echinoderms that have a hearts are a few species of the class Holothuroidea, which are the sea cucumbers (most do not). The other classes of Echinoderms do not possess a heart ever (Class Asteroidea, Class Ophiuroidea, Class Echinoidea)
Sea star or starfish (Asteroidea)Brittle stars, basket stars, serpent stars (Ophiuroidea)Sea urchins, heart urchins and sanddollars (Echinoidea)Holothurians or sea cucumbers (Holothuroidea)Feather stars and sea lilies (Crinoidea).
The difference between the two is that physical is terrain and political is location and cities.

Echinoderms are a category of sea invertebrates; there are 5 groups of echinoderms, Asteroidea, Crinoidea, Echinoidea, Holothuroidea and Ophiuroidea. A sea cucumber is a holothuroidea; their lengthy body surrounded by leathery skin identifies holothuroideas. A sea lily is a crinoidea; crinoidea feed off the seabed with a mouth at the top of their body.
