Derilissus is a genus of clingfishes belonging to the family Gobiesocinae found in the western Atlantic Ocean. This family of fish is identified by their appearance as small fish with sucking discs which allow them to attach themselves to various surfaces. Derilissus differs from other genera due to its attached gill membranes. [2]

Contents

Derilissus are found inhabiting rocky reef walls and on coral. There are five identified species in the genus Derilissus, all found around the Caribbeans. [3]

Description

Derilissus are typically small fish ranging from 1-3 cm in length, and usually are either pale brown and black or scarlet orange. Derilissus have slender bodies with a slightly depressed and narrow head that holds a short snout. [4] Most species of Derilissus have large eyes and lack a swim bladder. They do not have scales, and are instead protected by a thick layer of mucus. [5] Derilissus is unique from other genera of clingfish due to its attached gill membranes, which restricts the gill openings. [6] Derilissus possess a single row of crowded sharp teeth on both jaws, as well as a dorsal fin. [7]

As a clingfish, Derilissus possess a sucking disc located on the underside of the chest, which is formed primarily by modified pelvic fins. These discs are covered in papillae over most of its surface which allow it to cling to hard substrates such as coral and rocky reef walls. [8]

Species

There are currently five recognized species in this genus: [9] [10]

Distribution

Derilissus lives on corals or on rocky reef walls. They are found in the Western Atlantic, and have been documented in the Caribbean and the Bahamas. Different species of Derilissus inhabit different depths, with some living at depths as shallow as 30 meters to as deep as 265 meters.


The following is a table of preferred depths for members of the Derilissus family and their preferred substrate to cling onto.

Species NamePreferred Depths (m)Lives on
Derilissus altifrons68-69 [11] Coralline algae [11]
Derilissus kremnobates146-265 [11] Coral rubble banks [11]
Derilissus lombardii30-132 [11] Vertical reef walls and gorgonian corals [11]
Derilissus nanus31-51 [11] Coral heads [11]
Derilissus vittiger67-68 [11] Coralline algae [11]

Reproduction

Reproduction for Derilissus is not very well recorded, but clingfish reproduction typically begins with courtship initiated by the male. After nudging the female, both will shake together in parallel, until the female lays demersal eggs one by one onto a substrate. During this egg laying process which takes from several minutes to hours, the male fertilizes the eggs. [12]

Diet

Derilissus diet varies between each species, but they typically feed on benthic small crustaceans and gastropods such as copepods, isopods and sea snails. [12]

Life Stages

Derilissus eggs are hatched on substrates which the mother lays them upon. [12] After hatching, larval Derilissus are pelagic, and become benthic fish after reaching adulthood. [11]

Damselfish Group of fishes

Damselfish are those within the subfamilies Abudefdufinae, Chrominae, Lepidozyginae, Pomacentrinae, and Stegastenae within the family Pomacentridae. Most species within this group are relatively small, with the largest species being about 30cm in length. Most damselfish species exist only in marine environments, but a few inhabit brackish or fresh water. These fish are found globally in tropical, subtropical, and temperate waters.

Gobiesocidae Family of fishes

Clingfishes are fishes of the family Gobiesocidae, the only family in the order Gobiesociformes. These fairly small to very small fishes are widespread in tropical and temperate regions, mostly near the coast, but a few species in deeper seas or fresh water. Most species shelter in shallow reefs or seagrass beds, clinging to rocks, algae and seagrass leaves with their sucking disc, a structure on their chest.

Masked hamlet Species of fish

The masked hamlet is a species of marine ray-finned fish, a sea bass from the subfamily Serraninae which is part of the family Serranidae, which also includes the groupers and anthias. This species is found in the western Atlantic Ocean in the Caribbean Sea and has been recorded from the coast of Central America from Quintana Roo in Mexico to Bocas del Toro in Panama and from Jamaica to Puerto Rico, as well as in the Turks and Caicos and the Cayman Islands. Its specific name refers to Providencia Island, Colombia where the type was collected. It was also recorded from other islands in the Archipelago of San Andrés, Providencia and Santa Catalina. They are a unique species in the Hypoplectrus genus, defined by their unique color morph. Their behavior is largely similar to that of other hamlets, especially in their diet and egg-trading spawning patterns.

Bar jack Species of fish

The bar jack, also known as the carbonero, red jack, blue-striped cavalla or passing jack, is a common species of inshore marine fish classified in the jack family, Carangidae. The bar jack is distributed through the western Atlantic Ocean from New Jersey and Bermuda in the north to Venezuela and possibly Brazil in the south, with the largest population in the Gulf of Mexico and West Indies. The bar jack is most simply distinguished from similar jacks by its dark horizontal bar which runs along the back and down the caudal fin, often accompanied by an electric blue stripe immediately below it. Other more detailed differences include dentition and soft ray counts. The bar jack is a moderately large species, growing to a recorded maximum of 65 cm and a weight of 6.8 kg. The species inhabits clear shallow waters, often over coral reefs where it lives either solitarily or in large schools, taking various fishes, crustaceans and cephalopods as prey. Studies in Cuba indicate spawning occurs between March and August, with sexual maturity reached at 26 cm. It is a relatively popular sport fish and can be caught on light tackle with a variety of lures and baits. It is considered to be a good food fish, however many recorded ciguatera cases are attributed to the species, with most cases reported on the island of St. Thomas traced to this single species.

The golden hamlet was first described in 1852 by zoologist Felipe Poey (1799-1891) as Plectropoma gummigutta before being given its accepted name: Hypoplectrus gummigutta. It is found in the western Atlantic Ocean and occasionally makes its way into the aquarium trade.

<i>Gorgasia</i> Genus of fishes

Gorgasia is one of the two genera that belong to the subfamily Heterocongrinae. This genus is classified by the behavioral pattern of burrowing 75% of their bodies in the sandy substrate they live in and protruding their upper body into the water current above, giving the appearance that they are planted into the ground. This protruding behavior serves a multipurpose functionality to their survival.

<i>Lepadogaster</i> Genus of fishes

Lepadogaster is a genus of clingfishes native to the eastern Atlantic Ocean extending into the Mediterranean Sea. Lepadogaster belongs to class Actinopterygii. This means that they share many of the same characteristics as eels, ray-finned fish, and sea horses to name a few. The main characteristic of all of them though is having fin rays. These fin rays are made of webbed skin and are attached to portions of the body that connect fins to the bones. Lepadogaster species have a distinct difference in the formation of their dorsal and anal fins. While most other ray-finned fish spines, branched fin-rays, and middle radials, Lepadogaster species do not have these. Instead, they have cartilage in place of the mentioned features. These clingfish are mainly found near the rocky coasts and inside intertidal zones. Lepadogaster is known mostly as a clingfish, meaning that it spends most of its time attached to the surface of rocks.
