Description synthétique
Clés d'identification | Morphologie | Morphométrie
Plain ventral surface; reticulate pattern on dorsal surface; spiral valve with 11-14 turns.
Body shape (shape guide): other.
Inhabits estuaries and large rivers, often far upstream. Usually found over sandy substrates where it feeds on benthic invertebrates (Ref. 12693). Ovoviviparous (Ref. 50449).
Cycle de vie et comportement reproducteur
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). Distinct pairing with embrace (Ref. 205).
