Quality 0.00 · 2 views · Updated 1 month ago

Astroboa nuda, known as the naked basket star, giant basket star, or cream basket star, is a Gorgonocephalid basket star, a type of echinoderm. Its lengthy arms (spanning up to 1.0 metre (3.3 ft)) are highly branched. It inhabits reef slopes exposed to current throughout the Indo-Pacific, ranging from the Red Sea to New Caledonia. During the day, it coils into a tight ball inside a nook in the reef. At night, it spreads its arms to form a basket to feed on plankton.
