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..
More on author: Blyth.
Former synonym of Pateobatis uarnacoides (both previously under Himantura), but was resurrected as valid species (Ref. 114953).

Marine; brackish; benthopelagic; amphidromous (Ref. 51243); depth range ? - 30 m (Ref. 9840). Tropical

Max length : 84.0 cm WD male/unsexed; (Ref. 121648); 112.0 cm WD (female); max. published weight: 21.1 kg (Ref. 121648); max. published weight: 21.1 kg
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
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
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
= 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00832 (0.00364 - 0.01900), b=3.10 (2.89 - 3.31), 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
Resilience (Ref. 120179
): Low, minimum population doubling time 4.5 - 14 years (Assuming fecundity<100).
Fishing Vulnerability (Ref. 59153
): Very high vulnerability (90 of 100).
