Nadadeira dorsal

Small, located at the base of the tail, often barely visible.

Nadadeira caudal

Long, whip-like, without a stinging barb.

Dicas de identificação

1. 1

   Size

   The largest ray species, with disc widths typically ranging from 3 to 5 meters (10 to 16 feet), and exceptionally up to 7 meters (23 feet). Weight can exceed 1,350 kg (3,000 lbs).

2. 2

   Cephalic Fins

   Prominent, paddle-like cephalic fins that extend forward from the head, used to funnel food into the mouth. These are often rolled up when not feeding.

3. 3

   Mouth Position

   A wide, terminal mouth located at the very front of the head, rather than underneath the body.

4. 4

   Tail

   A relatively short tail compared to other rays, and crucially, it lacks a stinging barb.

5. 5

   Coloration and Markings

   Dark dorsal surface (black or dark grey) with white shoulder patches, and a white ventral surface with unique black spot patterns. The mouth is typically dark inside.
