📖 Overview

Occurs in relatively thick sand substrates (or maybe more like fine gravels), usually hiding almost entirely in the sand in subtidal zone. It darts out to catch prey (e.g. copepods) and then return to their original position. Females have mature eggs in their gonads from June to August and the eggs (522 per individual) are approximately 0.62–0.65 mm in diameter. On the other hand, a specimen from December lacked developed gonads .
