Etymology: Patagonotothen: Composed from Patagonia, the Argentinian province + Greek,noton = back + Greek, adverbial particle, then, that denotes distance or removal (Ref. 45335). More on author: Regan.
Environment: milieu / climate zone / depth range / distribution range
Marine; benthopelagic; depth range 50 - 500 m (Ref. 27363). Temperate; 36°S - 56°S, 69°W - 54°W
Southwest Atlantic: restricted to the Patagonian shelf.

Preferred temperature (Ref. 115969
): 4.5 - 9, mean 6 (based on 192 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00646 (0.00305 - 0.01366), b=3.18 (3.00 - 3.36), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.5 ±0.50 se; Based on food items.
Resilience (Ref. 69278
): Medium, minimum population doubling time 1.4 - 4.4 years (K=0.22-0.35; assuming fec < 10,000).
