The whole body is pure white, and the white dorsal process that branches finely is beautiful. As the scientific name "elegans" suggests, it has an elegant appearance. The densely growing process stands up and is pure white to the tip. The antennae are slightly cream colored.
Found on reefs and coral reefs, it attaches itself to the reef and feeds.
The individual photographed was around the end of July and was about 5cm in size.
Found attached to a rock about 3m deep on the reef of Arasaki. Its pure white body stood out in the sea. The white protrusions were swaying in the waves.
