Tortoises are a family, Testudinidae. Testudinidae is a Family under the order Testudines and suborder Cryptodira. There are fourteen extant families of the order Testudines, an order of reptile commonly known as turtles, tortoises, and terrapins. The suborder Cryptodira is a suborder of Testudines that includes most living tortoises and turtles. Cryptodira differ from Pluerodia in that they lower their necks and pull the heads straight back into the shells, instead of folding their necks sideways along the body under the shells’ marginals. The testudines are some of the most ancient reptiles alive. Tortoises are shielded from predators by a shell. The top part of the shell is the carapace, the underside is the plastron, and the two are connected by the bridge.

The carapace is fused to both the vertebrae and ribcage, and tortoises are unique among vertebrates in that the pectoral and pelvic girdles are inside the ribcage rather than outside. Tortoises can vary in dimension from a few centimeters to two meters. They are usually diurnal animals with tendencies to be crepuscular depending on the ambient temperatures. They are generally reclusive animals. Tortoises are the longest living land animal in the world, although the longest living species of tortoise is a matter of debate. Galápagos tortoises are noted to live over 150 years, but an Aldabra giant tortoise named Adwaita may have been the longest living at an estimated 255 years. In general, most tortoise species can live 80–150 years. — Wikipedia

    The discovery in 2019 of a lone small female tortoise living on one of the most inaccessible islands of the Galapagos Islands has baffled evolutionary biologists. Only one other tortoise, a large male discovered in 1906, has ever been found on Fernandina Island, an isolated island on the western edge of the iconic archipelago.

    Hawk moths are known for being some of the largest night fliers in the insect world. With wingspans of more than four inches, many species are big enough to comfortably fill the palm of your hand. Thanks to the work of a small team of researchers at the Florida Museum of Natural History, three new species from The Bahamas are breaking records at the opposite end of the size spectrum. At about the length of a vitamin pill, they are among the smallest discovered.

    Though gopher tortoises have persisted for millions of years, they now face a barrage of threats from loss of habitat and developers with permits that allow the reptiles to be buried alive.

    An international team of scientists, including Uwe Fritz and Christian Kehlmaier from Senckenberg, has made an astonishing discovery in the Zubbio di Cozzo San Pietro cave in Sicily, a burial site from the Copper/Bronze Age: bones of a giant tortoise. The skeletal fragments have been dated to 12,500 years ago, which is at odds with the temporal context of the other finds in the cave. Nevertheless, they are considerably younger than the previously known remains of extinct giant tortoises on the […]

    Archaeologists in Pompeii have discovered the remains of a pregnant tortoise that had sought refuge in the ruins of a home destroyed by an earthquake in 62 AD, only to be covered by volcanic ash and rock when Mount Vesuvius erupted 17 years later.
