Psamokóra Prstovitá

Overview

Psammocora digitata is a stony coral species characterized by its distinct growth form, which typically develops into submassive plates or thick, finger-like columns. While generally considered uncommon, it can be found across a wide range of reef environments throughout the Indo-Pacific region.

Appearance

This coral is recognized by its granular surface texture and small, shallow corallites that form subtle depressions. Its coloration varies, typically appearing in shades of purple, grey, brown, or yellow-green. The species can sometimes be confused with members of the genus Coscinaraea, though P. digitata is distinguished by its unique growth structure and specific skeletal features, such as its petaloid primary septa.

Biology & behavior

Colonies of P. digitata are often observed with their tentacles extended during the day, which helps them capture nutrients. Like many other stony corals, they rely on a symbiotic relationship with zooxanthellae for energy. While they are generally peaceful, they should be provided with adequate water flow to keep their surfaces clear of debris.
