Class+Holothuroidea+(Sea+Cucumbers)

Holothuroidea, known as sea cucumbers, lack the radial symmetry of other echinoderms. These creatures are long and tube-shaped, with a mouth at one end and an anus at the other end. The mouth of sea cucumbers features tentacles that help them retrieve food. Sea cucumbers regenerate missing body parts quickly.
