Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = No PD50 data [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00339 (0.00162 - 0.00707), b=3.10 (2.93 - 3.27), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

ຊັ້ນເຂດຮ້ອນ (Ref. 69278): 4.3 ±0.3 se; based on size and trophs of closest relatives

ຄວາມຢືດຢຸ່ນ (Ref. 120179): ຕຳ່, ປະຊາກອນຕຳ່ສຸດທີ່ໃຊ້ເວລາສອງເທົ່າ 4.5 - 14 ປີ (Preliminary K or Fecundity.).
