Stingray

Stingrays are flat-bodied rays in the suborder Myliobatoidei, known for their disc-shaped bodies and long tails, which in many species carry a venomous spine.

Stingrays are flat-bodied rays known for their venomous tail spines. They live in warm waters worldwide, including some freshwater species.

What it is

Stingrays are cartilaginous fish with broad, flattened bodies and pectoral fins forming a disc-like shape. Their long tails often carry a defensive spine that can inflict painful wounds. They are bottom-dwelling predators that feed on worms, clams, shrimp, and small fish. Species vary widely in size; some grow to about 6.5 feet and weigh up to 800 pounds.

Where it lives

Most stingrays inhabit shallow coastal waters in warm temperate and tropical regions. Some species are found in freshwater rivers and lakes, and a few live in open ocean waters. In Canada, stingrays are not native, but they appear in public aquariums and are studied in marine biology contexts.

Why it matters

Stingrays are generally not aggressive and sting only when stepped on or threatened. Their stings can be painful and, in rare cases, dangerous — most famously in the 2006 death of Steve Irwin. They are also ecologically important as bottom feeders and are popular in aquariums, making them relevant to Canadian readers through travel and conservation coverage.

In short

  • Stingrays are flat-bodied rays with a venomous tail spine.
  • They live in warm coastal waters and some freshwater habitats.
  • They feed on bottom-dwelling animals like worms and crustaceans.
  • Stingrays are usually not aggressive but can sting when threatened.
Canadian angle

Stingrays are not native to most Canadian waters, but they are relevant to Canadian readers through aquariums, travel, marine biology, and conservation coverage of warm-water species.

Quick questions

What is a stingray?
A stingray is a flat-bodied ray, a type of cartilaginous fish, with a long tail and, in many species, a venomous spine used for defence.
Are stingrays dangerous?
Stingrays are usually not aggressive, but their tail spines can inflict painful wounds if they are stepped on or otherwise threatened.
What is the difference between a stingray and a manta ray?
Stingrays usually have a defensive tail spine and live near the seafloor, while manta rays do not have a stinging spine and are more open-water swimmers.
