Synchiropus phaeton (from the Greek symphysis, “grown together”, cheir “hand” and pous, “foot”) is a bony fish from the Callionymidae family, the lyre fish. It can be found in the Mediterranean and the Eastern Atlantic .
description
Synchiropus phaeton is a relatively small fish with a sexual dimorphism in relation to size, with males generally growing larger than females. Males are on average 10-14 cm tall, but in rare cases can reach a maximum length of 18 cm. Female fish are on average about 6-10 cm long, but usually no larger than 12 cm. However, there have been reports describing female fish longer than 20 cm. This suggests that there must be even larger males that have not yet been spotted. Synchiropus phaeton is characterized by the large eyes that sit deep in their head and a sting on the gill cover, the preopercular sting. The orange to red colored body has olive green or yellow patterns on the back. The belly color varies between pink and silver. The dorsal fin has a black spot between the third and fourth rays, the anal fin has a black stripe through it.
distribution
Synchiropus phaeton can be found in the Eastern Atlantic along the coast of Portugal and south of the Azores up to the coast of Gabon. It is also found in the Mediterranean, where it can be found all the way to the coast of Israel and Cyprus. In the northern Adriatic Sea and the northern Aegean Sea is Synchiropus phaeton to find rare.
biology
Synchiropus phaeton is a deep sea fish that lives on the sea floor at depths of 80–650 m. Its habitat consists of muddy and sandy soils, where it feeds on small bottom invertebrates such as worms, snails and crustaceans. Male fish have a territorial behavior towards their conspecifics and react aggressively to them.
The reproduction of the bigeye lyrefish in the Mediterranean takes place from June to September. The eggs are released into the open water, where they develop pelagically into larvae.
Danger
Synchiropus phaeton occurs as bycatch in the octopus fishery in Senegal and in the Mediterranean trawling fisheries. Some fish of the lyrefish family are sold locally or traded as aquarium fish (Smith-Vaniz, WF 2015). There are no reports of major threats to Synchiropus phaeton . The population is classified as stable (Smith-Vaniz, WF 2015) and on the red list of endangered animal species as not endangered (eng .: “least concern”; German: “lowest concern”).
