Diademichthys lineatus, commonly known as the long-snout clingfish or urchin clingfish, is a species of marine fish in the family Gobiesocidae. [3]
The long-snout clingfish is a small type of fish, which can grow up to 5 centimetres (2.0 in). [4]
It has an elongated body and a stretched and spatulate snout. The snout is a criterion for recognizing the sex of the fish, since females have a longer and finer snout than males. This sexual dimorphism reflects a different diet between the two sexes. [5]
The body's background color varies from dark brown to red-brown, and the body has three yellowish longitudinal lines that run along it, one on the top of the body and the two others on the median axis of the sides of the fish. The caudal fin is marked by a yellow spot in its center, and the snout can also have some yellow coloration.
The longsnouted clingfish has been found to release a grammistin like toxic mucus on its skin. [6]
Long-snout clingfish are widespread throughout the tropical waters of the Indo-West Pacific region, inhabiting the region from the Gulf of Oman to Papua New Guinea. [7]
They are found in reef environments often associated with long-spined sea urchins particularly of the genus Diadema . [5]
Long-snout clingfish feed mainly on burrowing bivalves in corals, tube feet of their host, and eggs of a commensal shrimp. [5] The fish's sexual dimorphism is caused by a difference between the male's and the female's diet, causing the adult female to have a longer snout. The adult female eats small bivalves and shrimp's eggs more often than the adult males, who eat tube feet more frequently. [5]
Triggerfish are about 40 species of often brightly colored fish of the family Balistidae. Often marked by lines and spots, they inhabit tropical and subtropical oceans throughout the world, with the greatest species richness in the Indo-Pacific. Most are found in relatively shallow, coastal habitats, especially at coral reefs, but a few, such as the oceanic triggerfish, are pelagic. While several species from this family are popular in the marine aquarium trade, they are often notoriously ill-tempered.
The wrasses are a family, Labridae, of marine fish, many of which are brightly colored. The family is large and diverse, with over 600 species in 81 genera, which are divided into 9 subgroups or tribes. They are typically small, most of them less than 20 cm (7.9 in) long, although the largest, the humphead wrasse, can measure up to 2.5 m (8.2 ft). They are efficient carnivores, feeding on a wide range of small invertebrates. Many smaller wrasses follow the feeding trails of larger fish, picking up invertebrates disturbed by their passing. Juveniles of some representatives of the genera Bodianus, Epibulus, Cirrhilabrus, Oxycheilinus, and Paracheilinus hide among the tentacles of the free-living mushroom corals and Heliofungia actiniformis.
Lysmata amboinensis is an omnivorous shrimp species known by several common names including the Pacific cleaner shrimp. It is considered a cleaner shrimp as eating parasites and dead tissue from fish makes up a large part of its diet. The species is a natural part of the coral reef ecosystem and is widespread across the tropics typically living at depths of 5–40 metres (16–131 ft).
The graysby is a species of marine ray-finned fish, a grouper from the subfamily Epinephelinae which is in the family Serranidae which also includes the anthias and sea basses. It is found in the western Atlantic. It is associated with reefs and is a quarry species for commercial and recreational fisheries.
The orange-lined triggerfish is a demersal triggerfish. Although Balistapus is a monotypic genus, it is closely related to the genus Balistoides.
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.
The Banggai cardinalfish is a small tropical cardinalfish in the family Apogonidae. It is the only member of its genus. This attractive fish is popular in the aquarium trade. It is among the relatively few marine fish to have been bred regularly in captivity, but significant numbers are still captured in the wild and it is now an endangered species. The detrimental impact of humans on its environment and certain fatal diseases threaten this species' numbers significantly. Iridovirus diseases are known to be significant reason for fish mortality.
The Arabian carpetshark is a species of carpet shark in the family Hemiscylliidae, inhabiting coral reefs and other shallow coastal habitats from the Persian Gulf to India. Reaching 78 cm (31 in) long, this shark is characterized by a slender, plain brown body, and by two dorsal fins with straight trailing margins and the second smaller but longer-based than the first. The Arabian carpetshark feeds on bony fishes and invertebrates. Reproduction is oviparous with an annual cycle; females deposit egg capsules four at a time and the young hatch after 70–80 days. This small shark is often captured as bycatch but rarely used by humans. It has been assessed as Near Threatened by the International Union for Conservation of Nature (IUCN), as there is increasing fishing pressure and habitat degradation within its range. It does well in aquariums and has been bred in captivity.
The snowflake moray, also known as the clouded moray among many vernacular names, is a species of marine eel of the family Muraenidae. It has blunt teeth ideal for its diet of crustaceans, a trait it shares with the zebra moray.
The slippery dick is a species of wrasse native to shallow, tropical waters of the western Atlantic Ocean.
Aeoliscus strigatus, also known as the razorfish, jointed razorfish or coral shrimpfish, is a member of the family Centriscidae of the order Syngnathiformes. This unique fish adopts a head-down tail-up position as an adaptation for hiding among sea urchin spines. The razorfish is found in coastal waters in the Indo-West Pacific. Its natural habitat includes beds of sea grass and coral reefs, where sea urchins are found.
Spawn is the eggs and sperm released or deposited into water by aquatic animals. As a verb, to spawn refers to the process of freely releasing eggs and sperm into a body of water ; the physical act is known as spawning. The vast majority of non-mammalian, non-avian and non-reptilian aquatic and/or amphibious lifeforms reproduce through this process, including the:
The spiny seahorse, also referred to as the thorny seahorse, is a small marine fish in the family Syngnathidae, native to the Indo-Pacific area. It is classified as a Vulnerable species by the IUCN.
The bird wrasse, Gomphosus varius, is a species of the wrasse family.
The barred thicklip wrasse is a species of fish belonging to the wrasse family, native from the Indo-Pacific.
Hymenocera picta, commonly known as the harlequin shrimp, is a species of saltwater shrimp found at coral reefs in the tropical Indian and Pacific Oceans. It is usually considered the only species in the genus Hymenocera, but some split it into two species: H. picta from the central and east Pacific, where the spots are deep pinkish-purple with a yellow edge, and H. elegans from the Indian Ocean and west Pacific, where the spots are more brownish and have a blue edge. They reach about 5 cm (2.0 in) in length, live in pairs, and feed exclusively on starfish, including crown-of-thorns starfish. They do seem to prefer smaller, more sedentary starfish, but as these generally are not sufficiently numerous for their needs, they commonly attack crown-of-thorns starfish, both reducing its consumption of coral while under attack, and killing it within a few days.
The East Atlantic peacock wrasse is a species of wrasse native to the eastern Atlantic Ocean from Spain to Morocco and in the coastal waters of the Mediterranean Sea and the Black Sea. This species lives around rocks surrounded by eelgrass and can also be found in brackish waters in lagoons. It occurs at depths from 1 to 50 m. This species can reach 44 cm (17 in) in standard length, though most grow no larger than 25 cm (9.8 in). This species is sought as a game fish and is also important to local peoples as a food fish. It can also be found in the aquarium trade.
Doryrhamphus excisus is a species of flagtail pipefish from the genus Doryrhamphus. Its common names include blue-striped pipefish and blue-and-orange cleaner pipefish. The fish is found throughout much of the Indo-Pacific and tropical East Pacific.
Diplecogaster bimaculata, the two-spotted clingfish, is a species of fish in the family Gobiesocidae found in Black Sea, Mediterranean Sea and Atlantic Ocean where it is found on rocks and among seagrass or shell beds.
Antennatus coccineus, the scarlet or freckled frogfish, is a species of frogfish originally classified as Chironectes coccineus and Antennarius coccineus. It lives within tropical waters and has a central distribution being around Indo-East-Pacific areas- excluding Hawaii. The habitat of the scarlet frogfish is in the shallow zones of the ocean. It is found within reef areas, in rocky mounds or sponges where there are places for it to hide amongst from predators. The scarlet frogfish comes in a variety of colours, from tan and brown colours to bright reds and yellows and will grow to a maximum length of 13 centimetres (5.1 in). It can be identified taxonomically through its pectoral rays, the presence of dark patches that appear on its fins and body, along with its lack of distinctive tail base. The scarlet frogfish is not harmful to humans and is not caught by fisheries for consumption purposes, however it has been caught previously for studies relating to the abundance of reef-dwelling fish and as bycatch of shrimp trawling. Similar to other frogfish species, the scarlet frogfish is a predatory carnivore and exhibits a low degree of sociality, only interacting with other scarlet frogfish during their mating period.
