Are there any turtles that have a shell that is so big, so thick, and so hard that no other animal can eat it?

No.\n\nEven the largest sea turtles often have bites taken out of them by even larger sharks.\n\nThe gigantic tortoises of the Pacific islands, such as the famous Galapagos tortoise have among the hardest and thickest shells of any chelonian, but even they can be eaten.  Several species were wiped out by sailors who took them aboard ship to act as traveling rations, and later boiled or broiled them up and dug them out of their shells.\n\nThe largest turtle ever known, Archelon, likely had a thick, leathery shell much like the leatherback turtle today.  It lived at a time when there were huge marine predators like the pliosaur Kronosaurus in the water, who would have made short work of Archelon no matter what kind of shell it had.\n\nWhile a turtle's shell may offer protection from many enemies, it does not make them completely immune to predation.

A sea turtle.  You just float around, laxin' in the water, a lot of things can't or won't eat you, because of your shell and you get to be in the water (my favorite place) 24/7.  Check out a sea turtle next time you see one -- it's the ultimate zen!

Sea turtles of all species are endangered (for an excellent reference see James R. Spotila's book "Sea Turtles: A Complete Guide to Their Biology, Behavior, and Conservation"). The Leatherback, Kemp's ridley, and Hawksbill turtles are listed as Critically Endangered. The Olive ridley, Loggerhead, and Green turtles are considered Endangered. The Flat back is considered Data Deficient due to lack of research. They used to be hunted on a large scale in the whaling days for their meat, fat and shells. Coastal peoples have always gathered turtle eggs for consumption. Their biggest threat now comes from long-line fishing, and as bycatch in shrimp nets, as well as over development on nesting beaches. Each year it is said that 40,000 turtles die from longlines alone. According to researchers at the 24th Annual Symposium on Sea Turtle Conservation and Biology, in Costa Rica the Pacific Leatherback has ten years before extinction if nothing is done to reverse these problems. Small and inexpensive changes to fishing techniques, such as slightly larger hooks and traps from which sea turtles can escape, can dramatically cut the mortality rate. Another danger comes from marine debris, especially from abandonded fishing nets in which they can become entangled.\n\n \nSea turtle trapped in a fishing netBeach development is another large area which has threatened sea turtles. Since sea turtles return to the same locations to nest, these areas may be protected by special police. In some areas, such as the east coast of Florida, after the adult turtles lay their eggs, they are dug up and relocated to special fenced nurseries where they can be protected from beach traffic. This is not the best thing to do, as many turtle species return to the beach on which they were born. Special lighting ordinances may also be enforced to prevent lights from shining on the beach and confusing young hatchlings from thinking it is the moon or sun and crawling toward it, usually crossing a road.\n\nOne of the biggest threats to sea turtles is the black market trade in eggs and meat. This is a pervasive problem throughout the world, but especially a concern in India, Indonesia and throughout the coastal nations of Latin America. Estimates are as high as 35,000 turtles killed a year in Mexico and the same number in Nicaragua. Conservationists in Mexico and the United States have launched "Don't Eat Sea Turtle" campaigns in order to reduce the urban black market trade in sea turtle products. These campaigns have involved figures such as Pope John Paul II, Dorismar, Los Tigres del Norte and Mana.\n\nInjured sea turtles are sometimes able to be rescued and rehabilitated by professional organizations such as the Marine Mammal Center in Northern California.

Reptiles dont have the ability to move jaws laterally, so they cant chew the way mammals can.

Reptiles, although living "reptiles" are not a natural group. \nAmphibians have naked permeable skin and usually depend on aquatic environments for reproduction. Turtles, as amniotes, have keratinized skin (with scales) and lay terrestrial eggs.

The blue whale. It has been dubbed the largest animal that has ever lived on Earth; it bigger than even the biggest dinosaurs. It is on average between 80 and 100 ft. long. Females are bigger than males. The largest ever recorded when measurements were accepted world wide was 102ft. But befor there was standard world wide measurement, whaler claimed to have recorded a 108 foot blue whale, and a 110 foot blue whale; but scientist aren't sure how accurate those last two measerments are.\nThe baby is aslo the largest baby in the world.

No it is not true. The only law for a snapping turtle that I could find was one stating they can longer be run down by motorists. And that one is just sick!\n\nSnapping turtles aren't exactly an endagered species either.

Actually oysters are not the only mollusks that can produce pearls. Any bivalve mollusc, such as clams, mussels, cockles, etc. can make a pearl. However most of these pearls are not vaulable. The mantle of the animal creates the pearl. It also creates the shell. Therefore the exterior of a pearl will have the same appearance as the interior of the shell. Pearl oysters (not the kind of oysters we eat) have a highly glossy, iridescent interior. Therefore pearls which they produce are likewise highly glossy and iridescent, which is what gives them their value. A pearl from an ordinary edible oyster would just be dull white, with no gloss at all, because that's what the interior of an edible oyster's shell looks like. Fresh water mussels produce semiprecious pearls because their shells do have a "pearly" interior, though not as "pearly" as that of a pearl oyster.
