Icon Sea Star

Iconaster longimanus


Classic pentagon-shaped sea star, but with long, slender "fingers" extending from each point, covered in a mosaic pattern. Ocher in color, with the center in red, overlaid with a light-blue pattern of dotted lines. Also known as Icon Starfish, Double Sea Star, Double Starfish, Long-arm Sea Star, Long-arm Starfish, Mosaic Sea Star and Mosaic Starfish. They feed on molluscs, worms and detritus, and grow to a length of about 12cm.


Found singly or in groups on sand and rocky reefs on lower slopes, usually in deeper waters than most sea stars (up to 200m). Widespread in the West Pacific.

This is amazing! Not even made on purpose, looks like a painting.

Another mind-boggling spotting my good friend!
Unbelievably precious and so vivid!
It is reminiscent of tile floors from yesteryear.. like Roman times...
