8. Taxon Group: Echinodermata

This is part of the collection "DToL Taxon-specific Standard Operating Procedures (SOPs) for Marine Metazoa", lead by the Other Metazoa Working Group. The SOP collection contains guidance on how to process the various marine Metazoa species within the scope of the Darwin Tree of Life project. The guidance specifically refers to the tissue samples needed for DNA barcoding (which takes place at the Natural History Museum (NHM) and at the Marine Biological Association (MBA)) and outlines the dissected tissues required for whole genome sequencing, which takes place at the Wellcome Sanger Institute. Every specimen is submitted for DNA barcoding first before potentially being sent to the Wellcome Sanger Institute.

Definition: Within Echinodermata adults are recognisable by their (usually five-point) radial symmetry and include starfish (Asteroidea), brittle stars (Ophiuroidea), sea urchins (Echinoidea), sand dollars (Clypeasteroida) and sea cucumbers (Holothuroidea), as well as the sea lilies or "stone lilies" (Crinoidea).

Including: Aforementioned Asteroidea, Ophiuroidea, Echinoidea, Clypeasteroida, Holothuroidea and Crinoidea.

Excluding: Species smaller than 5mm.
