Cyrene Reef, Dec 10
Features: To 15-18cm, those seen much shorter, about 8-10cm. These fishes have a long and slender body, somewhat flattened sideways. The pointed snout had a lower jaw that is longer than the upper. Some have lovely gold 'eyelashes' over large eyes. The male fish has long filamentous extensions on his dorsal fin.

It is said that they hover in small groups above the sand. When threatened, they dive into the sand. Hence their common name.
