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.

How do Ophiuroidea eat?
Ophiuroidea, commonly known as brittle stars, feed by extending their arms to capture food particles such as zooplankton and detritus.

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,

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.
