Rays

Unwanted materials that are rejected or thrown away are commonly referred to as waste or refuse. These can include items such as garbage, trash, or litter that are no longer needed or have reached the end of their useful life. Proper disposal and management of this waste is essential for environmental sustainability.

The manta ray (the largest species of the rays) can reach more than 7.6 metres (25 ft) across, with a weight of about 2,300 kilograms (5,100 lb).

A manta ray uses its size as well as its speed to get away from predators as mantas do not have a poisonous barb on their tails like some other rays do. If a manta does survive a shark attack, it will visit feeding stations where smaller fish eat away dead skin and parasites that could be problematic for the ray later on.

You have to skin and gut the shark first. To cook it, you can barbecue the meat in foil, or you can bake it.

There are 70 species of stingrays with a variety of sizes from the size of your palm up to 14 feet in length. So the size of the young (pups) will vary too.

or Ray

Stingrays are considered fish, they belong to the family of the sharks.

yes there is there is 8 total

The lifespan of rays varies greatly by species. Some smaller rays (including electric rays) live only 20 years at most. Some species of stingrays can live up to 25 years old or slightly longer. The lifespan of manta rays can be as long as 50 years.

plankton and small fish occasionally

Stingrays can be up to 20 different colours

when the usually non-aggressive creatures feel threatened or are trodden on, they are capable of delivering horrific, agonising injuries by lashing out with the razor-sharp, barbed sting at the end of their tails. The barbs, which grow out of the bayonet-like sting like fingernails, are designed to snag in the flesh of the ray's unwary victim. Each barb is serrated and can be up to 20cm (8ins) long, and is coated with a paralysing toxin which the ray secretes along two grooves in its tail. It is only when the barb enters the body through the chest area, so that the heart or other vital organs are damaged and the poison is administered directly, causing the blood vessels to constrict, that very serious injuries can occur and death is more likely.

Most people assume it's straight up and down but actually the way to get the most out of the bench press and the actual way most people perform this exercise is taking it at a slight curve on the way down more towards the body, and pressing at a slight curve as you return the bar back up, curving it towards the rack, again this is a slight curve, not a huge one, the bench press just like any other exercise you need to master form before you start stacking on weight. If you were talking about anatomical motion of the bench press, then as you lower the bar in the movement, you are extending the upper arm at the shoulder joint while flexing the forearm at the elbow joint. While pressing the weight back up you are flexing the upper arm at the shoulder joint, and extending the forearm at the elbow joint

The point of intersection of light rays which have been intentionally manipulated to come to a point of converge, as we do with a parabolic reflecting surface, is called the focus. The parabolic reflector will (by virtue of mathematical principles and the physics of light) redirect parallel incoming rays back off its surface to the focus of the parabola. Links are provided.

Stingrays maintain homeostasis by having flexible pectoral fins and wide flat bodies. Most stingrays live in shallow water and are fairly docile animals who prey on other fish.

Manta rays can grow much bigger than stingrays. Mantas can grow up to 23 feet while stingrays can grow up to 6.5 feet.

no

Stingrays definitely do have hearts. The hearts on stingrays are located in the center of their bodies just like many other animals.

we eat them

Dasyatis say

no they are warm blooded.
