Stingrays hide themselves under the sand because their only other means of defense is the tiny barb on their tails. This is rarely enough to kill a predator, so they choose to hide so encounters are less frequent.
Stingrays have a poisonous barb on their tails that they only use in self-defense. Stingrays are generally docile and will swim near people in shallow waters. They also have sensors around their mouth called ampullae of Lorenzini, that help them detect electrical charges from their prey.
Stingrays have barbed stingers that can reach up to 14 inches in length. Manta rays do not have a sting barb. Manta rays are the larger species, reaching between 18 and 23 feet in width depending on the subspecies.

Honey bees don't bite they sting, and yes they do die after stinging, unlike wasps which will live to sting over and over again. The reason that honey bees die after stinging is because they cannot retract their sting barb which is an integral part of their body. ie, when the sting barb pierces your skin, the honey bee cannot withdraw the barb so its only method of escape is to leave the barb in your body, but the barb is such a large part of the bee's body that it cannot live without it and will be dead within a few minutes.
The Stingrays habitat is in the coastal tropical area and many hide in the sand. Stingrays are not aggressive, they will only attack if they have been stepped on, aggravated or threatened. They are venomous and can kill if the barb (stinger) gets close to a vital organ.
