Trichonotus arabicus, the Arabian sand diver, is a shallow-water, marine perciform fish in the family Trichonotidae.

The Arabian sand diver is a somewhat compressed, elongated fish growing to a maximum length of about 14.5 cm (6 in).

It is a demersal fish found close to the sandy seabed at depths of up to 2 m (6 ft 7 in).

[3] The Arabian sand diver is found in small groups feeding on zooplankton just above the seabed.

When alarmed, the fishes dive into the sand and remains stationary with just the upper parts of their head protruding from the sediment.
