A nocturnal species that form aggregations in caves by day and feeds on zooplankton at night.

A nocturnal species that form aggregations in caves by day and feeds on zooplankton at night (Ref. 2334). The smallest gravid female found was 8.61 cm SL and the largest 14.94 cm SL. These were found among collections made in October through March, although specimens from the early dates carried immature eggs. The smallest specimens, 3.03-3.18 mm SL from the Kermadecs, were collected in June, suggesting that juveniles settle early in the year. Over its entire range, collections are known from September to June (Ref. 88976).
