Xiphasia is a small genus of combtooth blennies found in the Pacific and Indian Oceans. [1]
The currently recognized species in this genus are: [1]
Combtooth blennies are blenniiformids; percomorph marine fish of the family Blenniidae, part of the order Blenniiformes. They are the largest family of blennies with around 400 known species. Combtooth blennies are found in tropical and subtropical waters in the Atlantic, Pacific and Indian Oceans; some species are also found in brackish and even freshwater environments.
Blenny is a common name for a type of fish. The term is ambiguous, having been applied to several families of percomorph marine, brackish, and some freshwater fish sharing similar morphology and behaviour. Six families are considered "true blennies", all grouped together under the order Blenniiformes; its members are referred to as blenniiformids. About 151 genera and nearly 900 species have been described within the order. The order was formerly classified as a suborder of the Perciformes but the 5th Edition of Fishes of the World divided the Perciformes into a number of new orders and the Blenniiformes were placed in the percomorph clade Ovalentaria alongside the such taxa as Cichliformes, Mugiliformes and Gobiesociformes.

Meiacanthus is a genus of combtooth blennies found in the western Pacific and Indian oceans. Many species in this genus make their way into the aquarium trade and several are venomous. The genus name Meiacanthus is derived from the Greek meion meaning "less" and akantha meaning "thorn" and refers to most species having relatively few dorsal fin spines.

Xiphasia matsubarai, the Japanese snake blenny, is a species of combtooth blenny found in the western Pacific and Indian oceans just extending into the Atlantic Ocean in False Bay, South Africa. This species can be found at depths ranging from the surface to 4,960 m (16,270 ft). This species reaches 30 cm (12 in) in SL. This species feeds primarily on bony fish, rising to the surface at night to feed. It can also be found in the aquarium trade.
Xiphasia setifer, the hairtail blenny or the snake blenny, is a species of combtooth blenny found in the western Pacific and Indian Oceans. This species reaches 53 cm (21 in) in SL and is the longest species of combtooth blenny. It can also be found in the aquarium trade.
Emblemaria is a genus of chaenopsid blennies found throughout the Pacific and Atlantic oceans.

Starksia is a genus of labrisomid blennies native to the western Atlantic Ocean and the eastern Pacific Ocean. Their typical length is 2 cm (0.79 in) SL. The generic name honours the American ichthyologist Edwin Chapin Starks (1867-1932) of Stanford University for his work on Pacific coastal fishes. As a genus Starksia is distinguished from other labrisomids by their scaled bodies, two obvious soft rays in the pelvic fin and the male's have an intromittent organ which is near to or attached to the first spine of their anal fins, which is also somewhat separated from the fin.
