The Dwarf Lionfish is a small species that has distinct spotted bands on the pectoral fins. It occurs in tropical and warm temperate waters of the Indo-Pacific region.

Standard Common Name

Dwarf Lionfish

Identification

The Dwarf Lionfish has large pectoral fins with distinct spotted bands. There is usually a short tentacle above the eye and variably developed leafy appendages on the head and lateral line.

The 13 venomous dorsal spines are about the same length or slightly shorter than the greatest body depth.

Body colouration is variable from red to brown.

Size range

The species grows to about 15 cm in length.

Similar Species

The Dwarf Lionfish looks similar to the Zebra Lionfish, Dendrochirus zebra. The easiest way to tell them apart is by the lack of spotted bands crossing the pectoral fins of the Zebra Lionfish.
