Rays

An alpha ray is a type of radioactive decay product that consists of two protons and two neutrons, which is essentially a helium nucleus. Alpha rays have low penetration power and can be stopped by a piece of paper or human skin.

Ray-finned fishes are a class of bony fishes called Actinopterygii. Their fins contain spines or rays. A finmay contain only spiny rays, only soft rays, or a combination of both. If both are present, the spinyraysare always anterior.

The class name for cartilaginous fishes is Chondrichthyes. These fishes have skeletons made of cartilage instead of bone, and include species such as sharks, rays, and skates.

Stingrays are typically found in shallow coastal waters, but some species have been known to swim to depths of up to 1,000 meters (3,300 feet). Their ability to dive to such depths allows them to inhabit a wide range of marine environments.

The stingray is a vertebrate, scientifically classified in the phylum Chordata. Its skeleton is made of cartilage instead of bone, but it still has a vertebrate skeleton. AND IT IS A CHORDATE
Stingrays are vertebrates

it is basically saying that without life, we are nothing. like a river without water it becomes a wasteland. anything else you wanna know? this is a lame question with an obvious answer.

It must be that time of the month for somebody

no. they swim. can't breath out of water. have gills for a reason, and they are related to sharks.

The value obtained is (2.983+/-0.015)×1010 centimeters per second.

sharks cannot survive on land because they will suffocate by their weight which can be almost two tons, they breathe by getting water to flow into their mouths and out of their gill silts and if they stop swimming they'll drown!

Very tricky question with a few answers. First off, no they can't fly. If you were to drop one from a plane however, it would glide down before splatting or "fall with style" as Buzz Lightyear would put it. It can also be argued that they do in fact fly, just under water. Hope this helps! =0)

Stingrays eyes are small, if you look at the Stingrays' eyes they are almost invisible, like little slits in the head of the animal.

no, if their stinger breaks off after stinging someone then it ill grow back at rate of about 5.75 inches per month.

yeah pretty sure most mammals do including us

You can find a stingray at the local aquarium, where most are available for safe petting. The only other way is to go into the ocean, and dive down to the bottom where all the bottom feeders are, and hope stingrays are there.

SHARKS AND RAYS HAVE CARTILAGE SKELETONS,WHICH MEANS THEY ARE VERY FLEXIBLE. I THINK.(peytonallentranum)

Stingrays are not endangered.

They have 2 eyes.

Yeah. I have one :)

Some species of stingrays are endangered due to pollution and overfishing. Some species of stingray that are endangered are the Ganges Stingray, Giant Freshwater Stingray, Izu Stingray, and the Marbled Freshwater Stingray.

The normal manta ray is usually non-aggressive, but it is capable of defending itself with its dangerous tail. A manta ray may also ram its foe, although this clumsy attack is treated as a secondary attack.

It was often thought that fish are always (on the Go) and feed frequently and do not need to rest. they do not sleep in the human or mammalian sense. maybe they do, but we know so little about the life in the depths.

as long as it takes untill it dies durrh

The stingray has eyes on top of its head so it lays in the sand but still be able to see its prey. Skates and rays have flatened bodies with the gill slits opening on the underside. The stingrays have a defensive strategy, a poisonous spine at the base of the tail. The stingrays pectoral fin allows the stingray to move by flapping of forming ripples. Because their eyes re on top of their bodies and their mouth is underneath, stingrays cannot see their prey instead they use smell.
