Rays

A group of sharks is called a gam, grind, school, herd, pod, collage, or shiver.

Tiger sharks are ovoviviparous, the eggs hatch internally and are born live fully developed. The gestation is approximately 13 months.

Lifespan is 20 years on average for a Devil Ray also known as the Manta Ray

Manta ray is their actual name. so it'd make more sense if you said:

Lifespan is 20 years on average for a Manta Ray also known as the Manta Ray.

just so you know.

Technically no, but the sides of their body act like fins.

maybey because they are venomus <3

Manta Rays grow to a much larger size than Stingrays, but I'd say the biggest difference is that Stingrays have a "stinger", a hard, thin rod-like appendage that lies in a groove in it's tail until it's frightened or threatened at which time it will will 'lift' it up, out and over it's back, and drive it into the flesh of it's perceived (or real) attacker and 'sting' it - it's very painful!

Manta Rays have a similar tail to Stingrays, but over evolutionary-time, they've "lost" the 'stinger'.

Stingrays are thought to be evolutionarily older than Mantas mainly because Mantas have evolved from being bottom filter-feeders into Open-Ocean filter-feeders while stingrays have remained bottom feeders. This is why, if you should go into the water where they are found (like off the coast of Australia), you will likely be warned to do the "Stingray Shuffle"....this frightens the rays away and helps you to avoid stepping on one - if you do, you most likely will be stung.

It was once thought that there was only one "type" of Manta Ray. But, it has been discovered that there are actually two:

- One is call the Giant Manta Ray and these Rays migrate around in the Ocean for long distances

- The other, first discovered, smaller and thought to be "older' Mantas stay closer to the shore

A believed to be newly discovered 'type' of Giant Ray is even larger than the other and have what some believe to be a vestigial stinger which can be seen on them as a small 'bump' at the base of the tail (vestigial = an evolutionarily 'withered', and basically useless to the 'modern' animal, body part - in humans, the appendix is thought to be vestigial)

The discovery of the Giant Rays with this (thought by some) vestigial, "bump" now have people wondering - Which 'came first' - The smaller, more common Manta, or the Giant?

Although Stingrays are more aggressive, by virtue of their "stinger", both are basically 'peaceful' creatures.

There are other differences between the Manta and Stingray, but I believe what I've mentioned suffices as the "major" differences.

No they do not.

ALittle bit Kind of Smooth And Just 2% Rough

It can get up to 6 ft. wide. i found that out on animal planet (river monsters). On river mosters he cuaght i sting ray that's was 6 ft. wide, 400 pounds, and when he had it in the net she had three baby sting rays. I hope this was the answer you were looking for.

Manta rays were once called devil fish by sailors who saw large "horns" extending forward from their heads. These horns turned out to be ingenuous scoopers which, when unfurled, guide plankton into the manta's mouth. Manta wingspans can reach up to 20 feet, and they glide though the water like birds. Both gentle and graceful, they have become a favorite attraction for divers. Their range is circumtropical, with sightings in the Atlantic from as far north as New England and south to Brazil. Mantas prefer plankton-rich waters and are regular visitors to a few select locations. In the winter, mantas visit San Benedicto Island, south of Cabo San Lucas, Mexico. Here, they glide past a pinnacle called The Boiler hoping to take advantage of the resident cleaner fish. Mantas also hang out in Yap, Micronesia at Manta Ridge, another cleaning station. From March through July, mantas visit the island of Tobago, feeding in the rich waters fed by the Orinoco estuary in South America. On Hawaii's Kona Coast, mantas are drawn each evening to the lights of a large hotel. Night divers watch as the mantas feed on the plankton that is attracted by the lights.

No if they don't bother them,then their fine.

Depending on the breed of a stingray, adults can vary from the size of a palm to having a body of six feet in diameter, with a tail length of fourteen feet. Adolescent stingrays will change in size as they grow older starting from hatching as an embryo of the size of your thumbnail. They are held in their mother's womb until they are mature enough to survive on their own.

no they don't the mother and father animals stay together but the group comes second to their young

I am 99% sure that stingrays are nektons

squid

lots

Mantids eat various creatures. But they usually eat creatures which are much smaller then them but in some cases the mantid will try to eat creatures the same size or even bigger.

It has also been know that a female Mantid will eat the male after mating. But this will only occur if the female mantis is hungry.

Personally i would recommend: Micro Crickets.

A stingray egg is encased in a hard outer shell often referred to as a 'mermaids purse'. It is a black colored square pocket with four curved spines one at each corner and vaguely resembles a purse shape. The ones I have seen are about seven to eight centimeters long.

I have no idea! This is hard! Why am I doing this?????

There is no real type of skin for cartilage fish. It varies..

they can have up to 100000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000 babies

While each species of ray and shark are just that, their own species, both rays and sharks are fish and both belong to the same subclass of cartilaginous fish known as Elasmobranchii. Skates, which look very similar to rays, are also part of this subclass of fish. For more information about the subclass Elasmobranchii, please see the Related Links.

Manta Rays are classified as Elasmobranchii, which is used to class other rays and sharks. The manta ray is a part of the eagle ray family of Myliobatidae.
