Marine biologists from Taiwan and New Zealand have identified four new species of deep-sea fish in the anglerfish genus Chaunax.
The Chaunacidae is a group of medium-sized fishes inhabiting the continental slope at depths of up to 1.6 miles (2.5 km).
The newly discovered species, named Chaunax flavomaculatus, C. mulleus, C. reticulatus and C. russatus, have been described in a paper published in the journal Zootaxa.
Chaunax flavomaculatus is about 4 – 5 inches (10 – 12 cm) in length and lives at depths of 1,150-1,312 feet (350 – 400 m).
The specific name of Chaunax flavomaculatus derives from the Latin wordsflavo (yellow) and maculates (spot), in reference to the fresh coloration of the dorsal body. The proposed common name of the species is Yellowspot frogmouth.
“Chaunax flavomaculatus is most similar to C. abei and C. endeavouri, with which it shares a mix of numerous bifurcated and simple dermal spinules.Chaunax flavomaculatus is unique in having many large yellow spots on the pinkish background of the dorsal surface when fresh, and a creamy white body when preserved,” the biologists wrote in the Zootaxa paper.
