Description
Purple soft corals grow in small colonies of up to 3 cm in height. The diameter of the individual polyps is 0.4 cm. They are usually bright purple, although they may be yellow, pink, red, dark grey or orange. The soft colony is encrusting and variably shaped. Feeding polyps extend eight tentacles into the water column.[3]
Distribution
This species is known from Saldanha Bay to Richards Bay off the South African coast, and lives from the low intertidal to 90m under water.
Ecology
This species feeds on microplankton. It is preyed on by the nudibranchs Leminda millecra and two extremely well camouflaged species from the genus Tritonia.[3]
