The velvet fish (Aploactinidae) live on the coasts of the tropical Indo-Pacific , most species in Indonesian and Australian waters. It is named after the converted, tiny scales, which give the fish a velvety appearance, but some species have no scales.
features
Her head is armored with spiky outgrowths. All fin rays are undivided. The dorsal fin begins in most species (not in Adventor and Peristrominous ) directly above the eye. The first three to five spine rays of the dorsal fin are usually not connected to the following by a fin membrane. In four species , the first three to four spine rays form a separate dorsal fin. The spine rays of the anal fin are not clearly defined or are absent. The pelvic fins have one hard and only two to three soft rays.
The animals have not yet been explored much.

The velvet fish are closely related to the stone fish (Synanceiidae). A characteristic that they share with the stone fish is a saber-shaped, defensive outgrowth of the lacrimale , the teardrop saber . Smith, Everman and Richardson therefore propose that the velvet fish be assigned to the stone fish as a subfamily.
