Mandarinfish [Synchiropus splendidus]

Mandarinfish

The Mandarinfish or Mandarin dragonet (Synchiropus splendidus), is a small, brightly colored member of the dragonet family, which is popular in the saltwater aquarium trade. The mandarinfish is native to the Pacific, ranging approximately from the Ryukyu Islands south to Australia.  It was later placed in genus Synchiropus. The common name of the Mandarinfish comes from its extremely vivid colouration, evoking the robes of an Imperial Chinese mandarin. Other common names include Mandarin goby, Green mandarin, Striped mandarinfish, Striped dragonet, Green dragonet and sometimes Psychedelic mandarinfish. The similarly named mandarin fish (Siniperca chuatsi), properly known as the Chinese perch, is only distantly related.

The Mandarinfish belongs to the perciform family Callionymidae, the dragonets, which counts 10 genera and more than 182 species. Genus Synchiropus counts 51 species, divided into 10 subgenera. The Mandarinfish is in subgenus Synchiropus (Pterosynchiropus) along with the Australian LSD-fish (S. occidentalis) and the LSD- or psychedelic fish (S. picturatus).

To date, S. splendidus is one of only two animal species known to have blue colouring because of cellular pigment, the other being the closely related LSD-fish Psychedelic Mandarin (S. picturatus). The name “cyanophore” was proposed for the blue chromatophores, or pigment-containing and light-reflecting cells. In all other known cases, the colour blue comes from thin-film interference from piles of flat, thin and reflecting purine crystals.

Mandarinfish are reef dwellers, preferring sheltered lagoons and inshore reefs. While they are slow-moving and fairly common within their range, they are not easily seen due to their bottom-feeding habit and their small size (reaching only about 6 cm). They feed primarily on small crustaceans and other invertebrates.

Oriental Flying gurnard [Dactyloptena orientalis]

flying gurnard

The oriental flying gurnardDactyloptena orientalis, is a flying gurnard of the family Dactylopteridae. This flying gurnard inhabits the Indo-Pacific Oceans at depths to 100 metres (330 ft). Their name is derived from the French word ‘gurnard’ meaning to grunt, for the grunting sound this fish makes.

The oriental flying gurnard is up to 40 centimetres (16 in) in length and is usually a grayish brown color with dark markings. The fish has huge, round pectoral finshaving many dark markings and a bright blue edge. The pectoral fins are normally held against the body, but when threatened the fins are expanded to scare predators which include sea breams and mackerel. The flying gurnard uses its pelvic fins to walk along the bottom of the ocean. The oriental flying gurnard feed on bony fish, bivalves, and crustaceans.

The ribbon eelRhinomuraena quaesita, or Bernis eel, is a species of moray eel, the only member of the genus Rhinomuraena. What is now known as Rhinomuraena quaesita also includes the former Rhinomuraena amboinensisR. quaesita was used for blue ribbon eels and R. amboinensis for black ribbon eels, but these are now recognized as the same species. The ribbon eel is native to the Indo-Pacific ocean.

The ribbon eel is an elegant creature with a long, thin body and high dorsal fins. The ribbon eel can easily be recognised by its expanded anterior nostrils. Juveniles and sub-adults are jet black with a yellow dorsal fin, while females are yellow with a black anal fin with white margins on the fins. The adult males are blue with a yellow dorsal fin. The ribbon eel grows to an overall length of approximately 1 m (3.3 ft), and has a life span of up to twenty years. The ribbon eel is the only moray eel that is protandric.
