Yellow stingray

What it is

This small ray has a nearly circular disc that is slightly longer than it is wide. Its tail is short and stout, ending in a leaf-shaped fin. A serrated spine sits halfway along the tail. The skin pattern varies greatly, showing either dark nets on a light background or bright spots on a dark base. It can change these tones quickly to match the seabed. Adults develop small thorns on their backs and tail edges. The underside is pale with darker spots near the rim.

Where it lives

It lives in the tropical western Atlantic, from North Carolina down to Trinidad. Common sites include the Gulf of Mexico, Florida Keys, Bahamas, and Caribbean islands. It prefers shallow inshore waters like bays, lagoons, and estuaries. Depths range from the water edge to 25 metres. It favours hard bottoms covered in invertebrates but also settles on sand, mud, or seagrass beds near coral reefs.

How it lives

During the day, it rests buried in sediment or lies still in vegetation. It stays within a small home area and hunts for shrimps, worms, and small fish. To find food, it may wave its disc to uncover buried prey or lift the front to create a shaded cave that attracts other organisms. It has excellent vision and hearing to spot predators like sharks. The ray also shows biofluorescence, glowing green under blue light.

Breeding and life cycle

Females carry developing young using yolk first, then uterine milk. They produce two litters annually after a five to six month pregnancy. Births peak in late summer and again in winter. Seagrass beds are key nursery grounds. Newborns emerge tail-first and are similar in look to adults, though wider. Males mature at a smaller size than females. Courtship involves males biting the female disc to hold position during mating.

Fish and people

Aquarium keepers value this ray for its small size and calm nature, though it needs ample space and soft substrate. It is the most common member of its family in North American pet markets. While not targeted by commercial fisheries, it is often caught by accident. Stepping on one can cause a painful wound from its venomous spine, but injuries are rarely fatal. Habitat loss in seagrass areas poses a threat.

Status and threats

The International Union for Conservation of Nature lists it as Least Concern. Its wide range and high numbers in places like the Florida Keys suggest a stable population. Small body size allows for faster reproduction, helping it withstand fishing pressure. No specific protection laws exist for this species, but its abundance keeps it safe from immediate risk.
