Etymology: Paranotothenia: Greek, para = near + Greek, noton = back + Greek, adverbial particle, then, that denotes distance or removal (Ref. 45335); magellanica: magellanica for the straits of Magellan, the type locality (Ref. 11892). More on author: Forster.

Marine; pelagic-oceanic; depth range 0 - 255 m (Ref. 11892), usually 0 - 20 m (Ref. 11892). Temperate; 43°S - 78°S
Southern Ocean: southern tip of South America. Also found in Falkland, South Georgia, South Orkney, South Shetland, Prince Edward, Crozet, Kerguelen, Heard and Macquarie islands, southern New Zealand and associated islands, rarely in the Ross Sea. New Zealand and Argentina (Patagonia) (Ref. 4537)

Estimates based on models
Preferred temperature (Ref. 115969
): 3.4 - 10.8, mean 7.9 °C (based on 130 cells).
Phylogenetic diversity index (Ref. 82805
= 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00661 (0.00312 - 0.01398), b=3.17 (2.99 - 3.35), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.4 ±0.4 se; based on size and trophs of closest relatives
Generation time: 4.2 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (K=0.26; Fec > 10,000).
Vulnerability (Ref. 59153
): Moderate vulnerability (41 of 100) .
