Many turtles from the same beaches show up at the same feeding areas. Once reaching sexual maturity in the Atlantic Oceans, the female Loggerhead makes the long trip back to her natal beach to lay her eggs. The Loggerhead sea turtle in the North Atlantic cover more than 9,000 miles round trip to lay eggs on the North American shore.
This is because in asexual reproduction a successful genotype can spread quickly without being modified by sex or wasting resources on male offspring who will not give birth. Some species can produce both sexually and through parthenogenesis, and offspring in the same clutch of a species of tropical lizard can be a mix of sexually produced ...
General American usage agrees; turtle is often a general term; tortoise is used only in reference to terrestrial turtles or, more narrowly, only those members of Testudinidae, the family of modern land tortoises; and terrapin may refer to turtles that are small and live in fresh and brackish water, in particular the diamondback terrapin ...
Parthenogenesis is a mode of asexual reproduction in which offspring are produced by females without the genetic contribution of a male. Among all the sexual vertebrates, the only examples of true parthenogenesis, in which all-female populations reproduce without the involvement of males, are found in squamate reptiles (snakes and lizards).

The semi-aquatic turtles that spend some time in the water, some on land, tend to have webbed feet with claws, while the fully aquatic marine turtles have flippers – and they can swim fast.
Ferti, a 42-year-old red-eared slider turtle, was put up for adoption by the Mid-Atlantic Turtle and Tortoise Society after her owner entered an assisted living facility.
The sand temperature is not the only thing that impacts sea turtles. The rise of the sea levels messes with their memory. They have an imprinted map in their memory that shows where they usually give birth and go after they do. With the rise in water levels, that map is getting messed up and is hard for them to get back to where they started.
Another example is the blue wildebeest, the calves of which can stand within an average of six minutes from birth and walk within thirty minutes; [5] [6] they can outrun a hyena within a day. [ 7 ] [ 8 ] [ 9 ] Such behavior gives them an advantage over other herbivore species and they are 100 times more abundant in the Serengeti ecosystem than ...
