more about our fishes
Anemonefish are fishes from the subfamily Amphiprioninae in the family Pomacentridae. About twenty-nine species are recognized, one in the genus Premnas, while the remaining are in the genus Amphiprion. In the wild they all form symbiotic mutualisms with sea anemones. Depending on species, clownfish are overall yellow, orange, reddish or blackish, and many show white bars or patches. The largest can reach a length of 18 centimetres (7.1 in), while some barely can reach 10 centimetres (3.9 in).
Clownfish lay eggs on any flat surface close to their host anemones. In the wild, clownfish spawn around the time of the full moon and the male parent guards them until they hatch about 6 to 10 days later.
Depending on the species, clownfish can lay hundreds or thousands of eggs. Clownfish were the first type of marine ornamental fish to be successfully bred in captivity on a large scale. It is one of a handful of marine ornamentals whose complete life cycle has been closed in captivity. Members of some clownfish species, such as the maroon clownfish, become aggressive in captivity; others, like the false percula clownfish, can be kept successfully with other individuals of the same species.
In captivity, the clownfish can live from 3 to 5 years. In the wild, they live 6 to 10 years.
The sweetlips, Plectorhinchus, are a genus in the family Haemulidae, with 35 species found in fresh, brackish and salt waters. These fish have big fleshy lips and tend to live on coral reefs in the Indo-Pacific in small groups or pairs. They will often associate with other fishes of similar species, and it is not unusual to see several species of sweetlips all swimming together. They are usually seen in clusters in nooks and crannies or under overhangs. Not until night falls do they venture from their shelters to seek out their bottom-dwelling invertebrate prey, such as bristleworms or shrimps and small crabs.
Sweetlips’ colouring and patterning changes throughout their lives. Adult ribboned sweetlips (Plectorhinchus polytaenia) develop increasing stripes with age. Juvenile sweetlips generally look quite different to the adults and often live a solitary life on shallower reef sections than those where the adults are found. Juveniles may be banded or spotted and are usually a completely different colour to the adult. Small juveniles have a strange undulating way of swimming, possibly mimicking poisonous flatworms as a means of camouflage.
The bluefin trevally, Caranx melampygus (also known as the bluefin jack, bluefin kingfish, bluefinned crevalle, blue ulua, omilu and spotted trevally), is a species of large, widely distributed marine fish classified in the jack family, Carangidae. The bluefin trevally is distributed throughout the tropical waters of the Indian and Pacific Oceans, ranging from Eastern Africa in the west to Central America in the east, including Japan in the north and Australia in the south. The species grows to a maximum known length of 117 cm and a weight of 43.5 kg, however is rare above 80 cm. Bluefin trevally are easily recognised by their electric blue fins, tapered snout and numerous blue and black spots on their sides. Juveniles lack these obvious colours, and must be identified by more detailed anatomical features such as fin ray and scute counts. The bluefin trevally inhabits both inshore environments such as bays, lagoons and shallow reefs, as well as deeper offshore reefs, atolls and bomboras. Juveniles prefer shallower, protected waters, even entering estuaries for short periods in some locations.
The bluefin trevally is a strong predatory fish, with a diet dominated by fish and supplemented by cephalopods and crustaceans as an adult. Juveniles consume a higher amount of small crustaceans, but transfer to a more fish based diet as they grow. The species displays a wide array of hunting techniques ranging from aggressive midwater attacks, reef ambushes and foraging interactions with other larger species, snapping up any prey items missed by the larger animal. The bluefin trevally reproduces at different periods throughout its range, and reaches sexual maturity at 30–40 cm in length and around 2 years of age. It is a multiple spawner, capable of reproducing up to 8 times per year, releasing up to 6 million eggs per year in captivity. Growth is well studied, with the fish reaching 194 mm in its first year, 340 mm in the second and 456 mm in the third year. The bluefin trevally is a popular target for both commercial and recreational fishermen. Commercial fisheries record up to 50 tonnes of the species taken per year in the west Indian Ocean, and around 700 lbs per year in Hawaii. The rapid decimation of the Hawaiian population due to overfishing has led to increased research in the aquaculture potential of the species, with spawning achieved in captivity. Despite its popularity as a table fish, many cases of ciguatera poisoning have been reported from the species.
The humphead wrasse (Cheilinus undulatus) is a wrasse that is mainly found in coral reefs in the Indo-Pacific region. It is also known as the Māori wrasse, Napoleon wrasse, Napoleonfish; or “So Mei” 蘇眉 (Cantonese) and “Mameng” (Filipino).
The humphead wrasse is the largest living member of the family Labridae, with males reaching 6 feet (2 m) in length, while females rarely exceed about 3 feet (1 m). It has thick, fleshy lips and a hump that forms on its head above the eyes, becoming more prominent as the fish ages. Males range from a bright electric blue to green, a purplish blue, or a relatively dull blue/green. Juveniles and females are red-orange above, and red-orange to white below. Some males grow very large, with one unconfirmed report of a Humphead Wrasse that was 7.75 feet (2.29 m) long and weighed 420 lbs (190.5 kg).
Adults are commonly found on steep coral reef slopes, channel slopes, and lagoon reefs in water 3 to 330 feet (1-100 m) deep. They are very opportunistic predators preying primarily on crustaceans, mollusks – particularly gastropods- fish, echinoderms. They are one of the few predators of toxic animals such as the sea hare Aplysia and boxfish Ostraciidae and have even been reported preying on crown-of-thorns starfish. This species actively selects branching hard and soft corals and seagrasses at settlement. Juveniles tend to prefer a more cryptic existence in areas of dense branching corals, bushy macroalgae or seagrasses, while larger individuals and adults prefer to occupy limited home ranges in more open habitat on the edges of reefs, channels, and reef passes. The species is most often observed in solitary male-female pairs, or groups of two to seven individuals.
Individuals become sexually mature at 5 to 7 years and females are known to live for around 30 years whereas males live a slightly shorter 25 years. Humphead wrasse are protogynous hermaphrodites, with some members of the population becoming male at approximately 9 years old The factors that control the timing of sex change are not yet known. Adults move to the down-current end of the reef and form local spawning aggregations they concentrate to spawn at certain times of the year.
The Mola mola or Sunfish, is the heaviest known bony fish in the world. It has an average adult weight of 1,000 kg (2,200 lb). The species is native to tropical and temperate waters around the globe. It resembles a fish head with a tail, and its main body is flattened laterally. Sunfish can be as tall as they are long when their dorsal and ventral fins are extended.
Sunfish live on a diet that consists mainly of jellyfish, but because this diet is nutritionally poor, they consume large amounts in order to develop and maintain their great bulk. Females of the species can produce more eggs than any other known vertebrate. Sunfish fry resemble miniature pufferfish, with large pectoral fins, a tail fin and body spines uncharacteristic of adult sunfish.
Adult sunfish are vulnerable to few natural predators, but sea lions, orcas and sharks will consume them. Among humans, sunfish are considered a delicacy in some parts of the world, including Japan, the Korean peninsula and Taiwan. In the EU, regulations ban the sale of fish and fishery products derived of the Molidae family. Sunfish are frequently, though accidentally, caught in gillnets, and are also vulnerable to harm or death from encounters with floating trash, such as plastic bags.
A member of the order Tetraodontiformes, which also includes pufferfish, porcupinefish and filefish, the sunfish shares many traits common to members of this order. It was originally classified as Tetraodon mola under the pufferfish genus, but it has since been given its own genus, Mola, with two species under it. The ocean sunfish, Mola mola, is the type species of the genus.
