The name echinoderm is from the Greek term for "spiny skin." Although not all of them have spiny skin, most have rough textures or spines that are toxic. Although most echinoderms are of small size, ranging up to 10 cm (four inches) in length or diameter, some reach relatively large sizes; e.g., some sea cucumbers are as long as two metres (about 6.6 feet), and a few starfishes have a diameter of up to one metre.
