Etymology: margaritella: Named for the smaller size of this stingray and of its pearl (Latin: margarita) spine, as compared to Dasyatis margarita (Ref. 26277).
Eponymy: Margaritella is the diminutive of Margarita and is used to show this species is smaller than its relative (see Margarita above). The vernacular name is not only used to convey ‘Little Pearl’ but to reflect the fact that this species has a pearl spine. (Ref. 128868), visit book page.

vertebrata, bertulang belakang: 116 - 128. Diagnosis: Dasyatis margaritella is the smallest dasyatid in West Africa (Ref. 26277). It is most similar to Dasyatis margarita, which is larger and has a larger pearl spine, and more numerous pectoral radials, 133-135 vs. 116-127 in D. margaritella (Ref. 26277). It is also similar to D. garouaensis, which has a much flatter disc and a longer snout (Ref. 26277).
Body shape (shape guide): other; Cross section: flattened.

Dasyatis margaritella is the most common littoral stingray on the West African coast and it enter lagoons, shallow bays and estuaries (Ref. 7397, 81259). Most likely feeds on small invertebrates (Ref. 114953). Ovoviviparous (Ref. 50449).
Siklus hidup dan perilaku kawin Kematangan | Reproduksi, perkembang biakan | Pemijahan | telur-telur | Fekunditas | Larva
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).
