Teleostei (teleosts) > Osteoglossiformes (Bony tongues) > Mormyridae (Elephantfishes)
Etymology: Pollimyrus: Because of Dr. Max Poll, ichthyologist + Greek, myros, -ou = the male of the morey eel; marianne: Named in honor of Marianne Elfriede Kramer, mother of Bernd Kramer.
Eponymy: Dr Max Fernand Leon Poll (1908–1991) was a Belgian ichthyologist, and ‘connoisseur of the fish fauna’. [...] Marianne Elfriede Kramer (1914–2000) was the mother of senior author Bernd Kramer. (Ref. 128868), visit book page.

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00562 (0.00244 - 0.01296), b=3.05 (2.85 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.3 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
