The vermiculated spinefoot (Siganus vermiculatus), also known as maze rabbitfish, scribbled spinefoot or vermiculate rabbitfish, is a species of marine ray-finned fish, a rabbitfish belonging to the family Siganidae. Like all rabbitfishes, it has venomous spines on the dorsal, anal, and pelvic fins. It is a reef associated fish species of the Indo-West Pacific region. It is a common commercially important fish in many tropical countries.
The vermiculated spinefoot was first formally described in 1835 as Amphacanthus vermiculatus by the French zoologist Achille Valenciennes with the type locality given as New Guinea. [3] The specific name vermiculatus refers to the vermiculated or maze pattern on the bodies of the living fish. [4]
The vermiculated spinefoot has a deep and laterally compressed body which has a depth which fits 1.9 to 2.2 times into its standard length. The nape is bulging with a slight indentation above each eye. The deep, blunt snout also bulges. The front nostril has a flange which is slightly widened to its rear. There is a recumbent spine to the front of the dorsal fin. [5] Like all rabbitfishes, the dorsal fin has 13 spines and 10 soft rays, while the anal fin has 7 spines and 9 soft rays. The fin spines hold venom glands. [2] The caudal fin is emarginate. [5] This species attains a maximum total length of 45 cm (18 in), although 30 cm (12 in) is more typical. [2] The body is covered in a grey and whitish complex maze-like or reticulate pattern with a patch of yellow on the head and spots on the caudal fin. [6]
The vermiculated spinefoot is found from southern India and Sri Lanka eastwards into the western Pacific Ocean as far east as Palau and Guam, south to Vanuatu, Fiji and New Caledonia and Australia. [1] In Australia it has been reported from Darnley Island and Townsville in northern Queensland but its presence in Australian waters needs to be confirmed. [6] It is found in shallow, coastal waters, especially estuaries. Both adults and juveniles are commonest[ clarification needed ] shallow, sediment-laden waters in mangroves, following the tide in and out. Adults are occasionally encountered in clear water in the vicinity of reefs or above sandy substrates. [6]
The vermiculated spinefoot browses algae which is growing on seagrass, the roost of mangrove and on rocks. The adults gather in aggregations of several hundred individuals to spawn in the summer, the pawn in pairs laying eggs which adhere to the substrate. [2] The lunar cycle governs spawning behaviour. [1]
This species produces venom in the spines of its fins. [2] In a study of the venom of a congener it was found that rabbitfish venom was similar to the venom of stonefishes. [7]
The vermiculated spinefoot is a large fast growing species and is sold fresh in markets in India, Sri Lanka and Fiji where it commpans[ clarification needed ] premium prices. [1] They are caught using nets and fixed traps. [5]
Rabbitfishes or spinefoots, genus Siganus, are perciform fishes in the family Siganidae. It is the only extant genus in its family and has 29 species. In some now obsolete classifications, the species having prominent face stripes—colloquially called foxfaces–are in the genus Lo. Other species, such as the masked spinefoot, show a reduced form of the stripe pattern. Rabbitfishes are native to shallow waters in the Indo-Pacific, but S. luridus and S. rivulatus have become established in the eastern Mediterranean via Lessepsian migration. They are commercially important food fish, and can be used in the preparation of dishes such as bagoong.
The foxface rabbitfish, also known as the foxface, black-face rabbit fish, badger fish or the common foxface is a species of marine ray-finned fish, a rabbitfish belonging to the family Siganidae. It is found in the Indian and Pacific Oceans. It can be found in the aquarium trade.
The blotched foxface, also called the blackblotch foxface or one-spot foxface, is a species of marine ray-finned fish, a rabbitfish belonging to the family Siganidae. It is found at reefs and lagoons in the central Indo-Pacific. Except for the black spot on the rear upper body, it resembles the closely related foxface rabbitfish.
The orange-spotted spinefoot, also known as the deepbody spinefoot, gold-saddle rabbitfish, golden rabbitfish, golden-spotted spinefoot, goldlined spinefoot or yellowblotch spinefoot, is a species of marine ray-finned fish, a rabbitfish belonging to the family Siganidae. It is found in the eastern Indian Ocean and western Pacific Ocean. It occasionally makes its way into the aquarium trade.
The masked spinefoot, also known as the masked rabbitfish, bluelined rabbitfish, blue-lined spinefoot, decorated rabbitfish or maiden spinefoot, is a species of marine ray-finned fish, a rabbitfish belonging to the family Siganidae. It occurs in shallow, coral-rich areas of clear lagoons and seaward reefs of the Indo-West Pacific region.
The blue-spotted spinefoot, the coral rabbitfish, coral spinefoot, ocellated spinefoot or orange spinefoot is a species of marine ray-finned fish, a rabbitfish belonging to the family Siganidae. It is found in the Indo-Pacific where it is often caught as a food fish and occasionally as an aquarium fish.
The streaked spinefoot, also known as the Java rabbitfish, blue-spotted spinefoot, blue-spotted trevally, Java spinefoot or white-spotted rabbit-fish, is a species of marine ray-finned fish, a rabbitfish belonging to the family Siganidae. It is found throughout most of the Indo-Pacific region.
The dusky spinefoot, also known as the squaretail rabbitfish, is a species of marine ray-finned fish, a rabbitfish belonging to the family Siganidae. It is native to the western Indian Ocean which has spread to the Mediterranean Sea through the Suez Canal. Its fin spines contain venom. It is regarded as a food fish.

Siganus sutor, the shoemaker spinefoot rabbitfish ,whitespotted rabbitfish or African whitespotted rabbitfish, is a species of marine ray-finned fish, a rabbitfish belonging to the family Siganidae.

S. sutor is one of the commercial marine fishes, which is ubiquitously caught, in Tanzania and the entire East African coast of the Indian Ocean.
