Lycodes

Lycodes is a genus of zoarcid fish in the subfamily Lycodinae.[1][2] It is the most species-rich genus in its taxonomic family as well as in the Arctic Ocean and adjacent waters. They occupy both shallow waters and deeper waters down to 3000 meters. A few species can occur in brackish waters.[3]

Description

The genus is characterized by one autapomorphy: submental crests, the more or less pronounced cartilage extensions on the lower jaws. Within the genus, one clade has been identified, the "short-tailed" Lycodes that are associated with shallower depths (0–1200 m) than the long-tailed species (3–3000 m). Short tail might represent an adaptation to shallow, Arctic waters; the clade includes many Arctic endemics. In contrast, the long-tailed species do not form a monophyletic group. Coloration of all short-tailed Lycodes includes some sorts of stripes, marks, or reticulations, while the long-tailed species are uniformly brownish, striped, or spotted.[3]

Ecology

Lycodes are bottom-dwelling fish with a relatively stationary life style. The eggs are benthic, few in number (<2000) and large in size (as large as 10 mm (0.4 in)).[3]

gollark: At least the `peripheral.find("modem", rednet.open)` bit.
gollark: Possibly.
gollark: Also, `local modem = peripheral.find("modem", rednet.open) ~= nil` could replace all your modem finding logic.
gollark: There's a perfectly good keys library.
gollark: Why do you have a table of key codes?
