Eleginops maclovinus

Eleginops maclovinus, the Patagonian blenny or rock cod, is a species of notothenioid fish[1] found in coastal and estuarine habitats around southernmost South America, ranging on half south of Chile on the Pacific side, and Argentina [2] on the Atlantic side.[3] It is also found around the Malvinas Islands, where it has been featured on a stamp.[4] It is the only member of its genus, which is the only member of the family Eleginopsidae.[5] Its English names refer to the vaguely blenny-, mullet-, or cod-like appearance, but it is not related to true blennies, mullets, or cods. Locally, it is often called róbalo,[6] a name also used for the common snook.

It is commonly fished in parts of its range.[7] It is an omnivore, tending towards carnivore. In some parts of its range, it is especially fond of Paracorophium,[6] but it is opportunistic, and its exact diet depends on the availability in the habitat where the individual fish lives.[3]

It reaches about 105 cm (3.44 ft) in length, and can live for 10 years.[3] It is a protandric hermaphrodite, and males predominate in lengths below 52 cm (1.71 ft), while female predominate above.[8] It has a diploid number of 48, and a fundamental number of 54.[5]

Religious significance to the indigenous people

The abundant and nutritious patagonian blenny were apparently not consumed in Tierra del Fuego and the rock art suggests they may have had some religious significance.[9]

gollark: Probably. I don't know if this is actually going to be any use, though.
gollark: I mean... arguably? Ish?
gollark: And some shell (probably two or more?) designed on the idea of passing around structured data objects instead of just text.
gollark: And a Python shell.
gollark: There's some C shell thing.
