How does the shape of a stingray help it survive?

Buoyancy. Stingrays lack the swim bladder and oil-filled liver that make fish buoyant. As a result, they start to sink when they aren't swimming. However, the stingray's flattened body and pectoral fins help them glide through the water.

How does the stingray protect itself?

Fins and Stingers

Many stingrays have sharp, venomous spines along their whip-like tail. They can defend themselves by lashing their tails out if threatened by a shark or other predator. At the Zoo, keepers trim the spines much like trimming fingernails, so the stingrays in this exhibit are safe to touch.

What is the structure of a stingray?

Their flattened bodies are composed of pectoral fins joined to their head and trunk with an infamous tail trailing behind. While the stingray's eyes peer out from its dorsal side, its mouth, nostrils, and gill slits are situated on its underbelly.

Why are stingrays important to the ecosystem?

Thanks to their unique way of feeding, large bottom-dwelling rays – such as stingrays, cownose rays, or whiptail rays – act as “habitat engineers”. Hovering over sandy areas, they excavate the sand in search of food while simultaneously creating micro-habitats for various tiny invertebrates.

Do stingrays have teeth?

Stingrays don't have teeth like we do. They have dental plates with rows of small, flat teeth. Much like sharks, rays replace their teeth.

What do stingrays like eating?

Freshwater stingrays eat crustaceans and other invertebrates. Their powerful jaws can easily crush the shells of clams and mussels, and they will occasionally eat small fish. At the Smithsonian's National Zoo, the stingrays eat shrimp, earthworms, smelt and an aquatic omnivore gel diet.

How do stingrays regulate buoyancy?

Rays have a comparatively large, oily liver that helps maintain their buoyancy as oil is positively buoyant in water. In addition, having a relatively lightweight skeleton made of cartilage helps rays efficiently maintain buoyancy.

Can stingrays bite you?

When a stingray whips its tail at you, one or more of its spines may pierce your skin. The sheath around each spine then breaks apart and releases venom into the wound and surrounding tissue. Stingrays most often sting people in their feet, ankles, and legs, but sometimes a sting may occur elsewhere on the body.

Does it hurt a stingray to remove its barb?

In that case, the potential for complications is so great that only a doctor should attempt removal. Because barbs are serrated, they tear at flesh when removed, and it's unlikely that pulling them out will lower exposure to any venom.

Can a stingray shoot its barb?

Stingrays can only use their barb defensively, which means there's really no such thing as a “stingray attack.” According to the American Museum of Natural History, “When triggered by pressure on the back of the stingray, the tail is suddenly and powerfully thrusted upward and forward, into the victim, which makes the ...

Is a stingray a shark?

Who are the Stingrays? The stingrays are part of a unique group of fishes known as “batoids” and are closely related to sharks. A stingray's body is made of cartilage like a shark's body so sometimes they are called “flat sharks”!

Can a dead stingray still sting?

Even after a stingray's death, the venom it produced while alive would still be a threat to humans. A person is far more likely to suffer a painful injury and possible complications from contact with a spooked stingray than death.
