Elongate, with a heart-shaped disk terminating in a wedge-shaped snout with a few enlarged tubercles on tip (Ref. 26938). Ashy gray to olive brown or chocolate brown.

Biologie     Verklarende woordenlijst (bv. epibenthic)

Inhabits sandy and weedy bottoms, sometimes near patch reefs. Also found along beaches from shoreline to depths of 30 m (Ref. 26938). Usually buried in the sand or mud. Feeds on mollusks and crustaceans. Ovoviviparous, with up to 6 in a litter (Ref. 12951). Size at birth 20 cm (Ref. 12951). Generally uncommon (Ref. 9710).

Levenscyclus en paargedrag Maturiteit | Voortplanting | Paaien | Eieren | Fecunditeit | 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).

Estimates based on models

Preferred temperature (Ref. 123201): 23.4 - 27.8, mean 26.3 °C (based on 280 cells).
Fylogenetische diversiteitsindex (Ref. 82804):  PD50 = 0.5039   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00282 (0.00135 - 0.00588), b=3.12 (2.95 - 3.29), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trofisch niveau (Ref. 69278):  3.6   ±0.50 se; based on food items.
