Pedata

Pedata, an order of Sea-cucumbers or Holothurians including those with well-devoloped tube feet (pedicels or pedia) which are the most typical forms. It is subdivided into two sub-orders: the Dendrochirotte, in which the tentacles are arborescent, and the Aspidochirotte, in which the tentacles are simple and peltate. The former is represented by the common British Psolus, and the latter by the type-genus Holothuria or cotton-spinner.
