		Howell, K.L., Billett, D.S.M. and Tyler, P.A. Depth-related distribution and abundance of seastars (Echinodermata: Asteroidea) in the Porcupine Seabight and Porcupine Abyssal Plain, N.E. Atlantic.
		The depth-related distribution of seastar (Echinodermata: Asteroidea) species between 150 and 4950 m in the Porcupine Seabight and Porcupine Abyssal Plain is described.
		Diversity is greatest at ~1800 m, decreasing with depth to ~2600 m before increasing again to high levels at ~4700 m.

	Introduction to the Asteroidea (Site not responding. Last check: 2007-11-01)
		True starfish are classified in the Asteroidea, a group of echinoderms.
		Unlike the superficially similar brittle stars (Ophiuroidea), true starfish have no sharp demarcation between arms and central body, and they move using tube feet rather than wriggling movements of the whole arms.
		Many, but not all, starfish are able to turn a portion of their stomachs out through the mouth, and thus digest food outside of the body.

	eMedicine - Echinoderm Envenomations : Article Excerpt by: Scott A Gallagher, MD, FACEP
		Background: The phylum Echinodermata includes a diverse group of marine animals that are slow moving and nonaggressive, including brittle stars (class Ophiuroidea), starfish (class Asteroidea), sea urchins (class Echinoidea), and sea cucumbers (class Holothuroidea).
		Pathophysiology: While most echinoderms are poisonous, and many have sharp spines or spicules capable of causing injury, only a few members of the Asteroidea, Echinoidea, and Holothuroidea classes are capable of causing venomous injuries in humans.
		Starfish (Asteroidea) envenomation in humans is well described, with the crown-of-thorns starfish (Acanthaster planci) as the main culprit (see Image 1, Image 2).

		Among the most conspicuous invertebrates on the reef are the echinoderms (from the Greek for "spiny skin") such as the starfish (or sea stars) and the sea urchins.
		The most prominent of the starfish (asteroidea) are the bright blue Linckia laevigata which are quite common in the reef flat.
		HE PINCUSHION STAR is a common inhabitant of shallow patch, barrier, and fringing reefs.

	Evolution
		An example of this are the sea urchins and brittle stars, a group, which both form pluteus larvae.
		("echinoderms") There are a total of six classes identified in the echinoderm phylum which are, asteroidea, ophiuroidea, echinoidea, crinoidea and holothuroidea.
		The controversy comes in when deciding if Ophiuroidea and Asteroidea form a sister clade.

	Picture of the Week: Starfish - Asteroidea
		Illustrated here are the larval and adult forms of starfish class Asteroidea, phlyum Echinodermata.
		The phlya comprises five extant classes: the Crinoidea (feather stars and sea lilies), the Asteroidea (starfish), the Echinoidea (sea urchins and sand dollars), the Holothuroidea (sea cucumbers) and the Ophiuroidea (brittle stars).
		They number about 6000 living species and have a fossil record extending back over 500 million years.

		For some Chinese, Malay, and Pacific Island gourmets, properly prepared sea cucumbers are prized as a delicacy (eg, beche-de-mer, trepang).
		However, a clear link between echinoderm envenomation and death (other than subsequent drowning) cannot be found in the literature, despite several anecdotal reports of fatalities (Freyvogel, 1972; Marsh, 1986; Edmonds, 1989; Smith, 1977).
		Of the phylum Echinodermata, only starfish (class Asteroidea), sea urchins (class Echinoidea), and sea cucumbers (class Holothuroidea) are capable of envenomation.

	Starfishes
		The Class Asteroidea ("star form") includes animals commonly called starfish or sea stars.
		Most forms have a flattened and flexible body with a varying number (often five) arms, or rays, arranged around a central disc.
