Mandarinfish

Last updated

Its common name comes from its vivid colouration, which evokes the robes of an Imperial Chinese mandarin.[1] The dragonet family Callionymidae, to which the mandarinfish belongs, contains over 182 species across 10 genera.[2] Albert William Herre, an American ichthyologist working in the Philippines, originally named the species Callionymus splendidus in 1927.[3]

Biology and range

The specific epithet splendidus is Latin for "bright" or "glittering".[1] Mandarinfish have a layer of slime instead of scales, which blocks disease and may discourage predators.[4] Researchers proposed the term "cyanophore" to describe the blue pigment-containing cells found in this fish.[5] Except in this species, blue coloration in animals results from structural thin-film interference created by layered purine crystals.[5]

Sadovy et al. (2001) examined the gut contents of seven wild mandarinfish and found they consume harpacticoid copepods, polychaete worms, small gastropods, gammaridean amphipods, fish eggs, and ostracods.[6] During daylight hours, wild mandarinfish feed continuously, selectively pecking at small prey items found on coral substrate.[6]

What the specialist sources record

The GBIF Backbone Taxonomy accepts Synchiropus splendidus (Herre, 1927) as a species in the order Perciformes and family Callionymidae.[7] GBIF holds 732 occurrence records for this taxon as of 17 October 2026.[7] Laos issued a 39-kip postage stamp featuring the mandarinfish in 1987.[8] On 26 August 1993, the Federated States of Micronesia released a 40-cent stamp depicting the mandarinfish.[8]
