Description synthétique Morphologie | Morphométrie

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. Entire upper surface is thickly freckled with several hundred small whitish dots. Lower surface is pale yellow or yellowish white or plain white, fins slightly darker than trunk (Ref. 6902).

Biologie     Glossaire (ex. 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).

Life cycle and mating behavior Maturité | Reproduction | Frai | Œufs | Fécondité | Larves

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).
