Rays

The skin of rays is similar to that of sharks. It's not the skin, but the placing of the scales is different on each animal. Both sharks and stingrays have scales called dermal denticles (meaning skin teeth). Each scale has the same structure as a shark's tooth. The difference is that a shark's dermal denticles are all aligned pointing to the rear of the shark while a ray's scales are more spread apart and are in an irregular pattern. Sting rays are smooth creatures that feel something similiar to velvet. They feel strong, but the skin feels as if it has a slime coating, though none will deposit on your hands if you touch them.

Stingrays can vary in weight depending on the species, but they typically range from about 50 to 500 pounds.

A Stingray typically weighs between 80 to 790 pounds, depending on the species and size.

Stingrays generally live between 15 to 25 years in the wild, although some species have been known to live for up to 25-30 years. Captive stingrays can sometimes live longer, up to 25-30 years or even more, depending on the care and conditions provided in captivity.

Rays have specialized mouth structures that allow them to crush and grind their food before swallowing it. They primarily feed on bottom-dwelling prey such as mollusks, fish, and crustaceans, which they detect using their electroreceptor organs. Rays use their teeth plates or specialized tooth-like structures to crush and consume their food.

Stingrays require a tank size of at least 75 gallons for smaller species and more than 200 gallons for larger species to provide enough space for them to swim and explore. Overcrowding can lead to stress and health problems for stingrays. Ultimately, the tank size should be determined based on the specific species and number of stingrays being kept.

yes there is something positive they are used in x rays and radiation. but they are very powerful they can penetrate concrete!

gamma rays can be used to kill insects and bacteria on foods. they are also used to steralize medical equipment. gamma rays also have a tissue penetrating property, making them useful in CT scans!

The refraction of light when it passes from a slow medium (high density) to a fast medium (low density) causes the light to change speed and thus it bends away from the normal to the boundary between the two media. The amount of bending also depends on the indices of refraction of the two media and is described quantitatively by Snell's Law.

Gamma radiation has a very short wavelength. This is dangerous to us soft-tissued mammals because our body's natural defenses (like our skin) are unable to keep the radiation out. Gamma radiation has been linked to cancer under the assumption that our cells, once exposed, can be mutated into a cancerous cell.

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)
