The snake prickly backs (Lumpenidae) are a fish family from the group of eel mother relatives (Zoarcales). All eleven species in the group are bottom-dwelling marine fish that are found mainly in the cool waters of the northern Pacific and with three species also in the North Atlantic.

features

The body of the serpentine back is elongated and covered with small scales; the head without the skin flaps or other skin outgrowths so typical for many spiked backs. The "cheeks" are scaled, with Lumpenella the whole head. The number of vertebrae is 60 to 87. The Lumpeninae are 7.8 to 70 cm long. The anal fin has one to five fin spines at its beginning. The pectoral fins are large; the number of pectoral fin rays is 12 to 16. The pelvic fins have one hard and two to three soft rays. The number of Branchiostegal rays is six. The channels of the sideline system on the head are reduced. The sideline is absent on the body, there is a mediolateral line of neuromasts .

Almost nothing is known about the way of life of the Lumpeninae.

Systematics

The snake spine backs were scientifically introduced in 1898 as a subfamily of the spine backs (Stichaeidae) by the American ichthyologists David Starr Jordan and Barton Warren Evermann . In 2015, the Russian scientist OA Radchenko made the snake spine back into an independent family after he determined with the help of molecular biological data that they are more closely related to the crooked mouths (Cryptacanthodidae) and the Zaproridae than to the spine backs . This was adopted in the Catalog of Fishes in mid-2018.
