Etymology: Pateobatis: Combination of Latin 'pateo' for 'lie open, be exposed' and 'batis' for skate, ray or flatfish; referring to the eclectic nature of members of this group.
Eponymy: Dr Pieter Bleeker (1819–1878) was an ichthyologist and army surgeon commissioned (1841) by the Dutch East India Company. [...] (Ref. 128868), visit book page.

Enters estuaries (Ref. 4832). Found mainly on muddy bottoms to at least 40 m depth. Most likely to feed on small crustaceans (Ref. 114953). Ovoviviparous (Ref. 50449). Feeds on bottom-living invertebrates (Ref. 68964).

Life cycle and mating behavior Geschlechtsreife | Fortpflanzung | Ablaichen | Eier | Fecundity | Larven

Exhibit ovoviparity (aplacental viviparity), with embryos feeding initially on yolk, then receiving additional nourishment from the mother by indirect absorption of uterine fluid enriched with mucus, fat or protein through specialised structures (Ref. 50449). Distinct pairing with embrace (Ref. 205).

Estimates based on models

Preferred temperature (Ref. 123201): 26.6 - 29.3, mean 28.6 °C (based on 2266 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01023 (0.00486 - 0.02155), b=3.06 (2.87 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.5 se; based on size and trophs of closest relatives

Widerstandsfähigkeit (Ref. 120179): niedrig, Verdopplung der Population dauert 4,5 - 14 Jahre. (Assuming fecundity<100).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (90 of 100).

Preiskategorie (Ref. 80766): Low.
