Elefante é o termo genérico e popular pelo qual são denominados os membros da família Elephantidae, um grupo de mamíferos proboscídeos elefantídeos, de grande porte, do qual há três espécies no mundo atual, duas africanas (Loxodonta sp.) e uma asiática (Elephas sp.). Há ainda os mamutes (Mammuthus sp.), hoje extintos. Até recentemente, acreditava-se que havia apenas duas espécies vivas de elefantes, o elefante-africano e o elefante-asiático, uma espécie menor. Entretanto, estudos recentes de DNA sugerem que havia, na verdade, duas espécies de elefante-africano: Loxodonta africana, da savana, e Loxodonta cyclotis, que vive nas florestas. Os elefantes são os maiores animais terrestres da actualidade pesando até 12 toneladas e medindo em média quatro metros de altura. As suas características mais distintivas são as presas de marfim.

Elephants are large land mammals in two genera of the family Elephantidae: Elephas and Loxodonta. Three species of elephant are living today: the African Bush Elephant, the African Forest Elephant and the Asian Elephant (also known as the Indian Elephant). All other species and genera of Elephantidae are extinct, some since the last ice age: dwarf forms of mammoths may have survived as late as 2,000 BC.[1] Elephants and other Elephantidae were once classified with other thick-skinned animals in a now invalid order, Pachydermata.

Elephants are the largest land animals now living.[2] The elephant's gestation period is 22 months, the longest of any land animal. At birth it is common for an elephant calf to weigh 120 kilograms (260 lb). They typically live for 50 to 70 years, but the oldest recorded elephant lived for 82 years.[3] The largest elephant ever recorded was shot in Angola in 1956. This male weighed about 24,000 lb (11,000 kg),[4] with a shoulder height of 3.96 metres (13.0 ft), a metre (yard) taller than the average male African elephant.[5] The smallest elephants, about the size of a calf or a large pig, were a prehistoric species that lived on the island of Crete during the Pleistocene epoch.[6]

Elephants are a symbol of wisdom in Asian cultures and are famed for their memory and intelligence, where they are thought to be on par with cetaceans[7] and hominids.[8] Aristotle once said the elephant was "the beast which passeth all others in wit and mind".[9] The word "elephant" has its origins in the Greek ἐλέφας, meaning "ivory" or "elephant".[10]

According to observations so far, healthy adult elephants have no natural predators,[11] although lions may take calves or weak individuals.[12][13] They are, however, threatened by human intrusion and poaching.

os elefantes o elefántidos (Elephantidae) son una familia de mamíferos placentarios del orden Proboscidea. Antiguamente se clasificaban, junto con otros animales de piel gruesa, en el orden, ahora inválido, de los paquidermos (Pachydermata). Existen hoy en día tres especies y diversas subespecies. Entre los géneros extintos destaca Mammuthus que incluía los mamuts.


Galapagos tortoises (Chelonoidis nigra sp.) on Isabela, Galapagos Islands
animals that are extinct

This young (probably 10-15 yrs) tortoise was apart of a population of released tortoises here in the southern portion of Isabela Island. Reportedly, the tortoises in this area had become locally extinct, and so the only tortoises we saw in this region were apart of this reintroduced group, thus they were all small and young. It was pretty common to see them on the side of the road and find their poop along the trails. Their feces is composed of essentially just a skeleton of dry cactus fibers, once the moisture dries out, and seems to stick around for a while. We actually found some of their feces on a tall staircase that went up to a watch out point (each step was probably about 3-5 in tall, 2-3 ft wide, so it's not entirely unbelievable that they could climb up so far, but the question is "why?").
