Etymology: Platanichthys: Derived from Platanistius, epitet of Apollo with the meaning of "the king of a flat tree". This tree is Planera acuatica and grows in swampy areas. This voice is also related to the Mammalia family Platanistidae; + Greek, ichthys = fish (Ref. 45335). More on author: Regan.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; brackish; pelagic; depth range - 50 m (Ref. 188), usually - m (Ref. ). Subtropical; 0°C - ; 25°S - 36°S, 62°W - 47°W (Ref. 188)
South America: just north of Rio de Janeiro, Brazil to Uruguay and Argentina.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 9.7 cm SL male/unsexed; (Ref. 55642); common length : 5.0 cm SL male/unsexed; (Ref. 188)
soft rays: 12 - 23. Belly sharply keeled. Anterior (first) supra-maxilla minute or absent (cf. Ramnogaster); posterior frontal fontanelles on top of head retained in adults; no sharp retrorse spine near front of maxilla (cf. Rhinosardinia); no fleshy outgrowths on the hind margin of the gill opening (cf. Sardinella and Harengula); silver lateral stripe present (cf. Sprattus fuegensis).
Probably confined to freshwaters and brackish waters of lagoons, estuaries and the lower reaches of rivers.

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00794 (0.00511 - 0.01236), b=3.11 (2.98 - 3.24), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245
Trophic level (Ref. 69278
): 3.0 ±0.1 se; based on diet studies.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (12 of 100) .
