Turtles inhabit virtually every terrestrial, aquatic and marine habitat in the world that is warm enough to permit activity. Turtles are residents of every continent except Antarctica and of all the world’s temperate and tropical oceans.Know More
The 327 living turtle species exhibit remarkable diversity, and they have colonized most available habitats. Some species live in deserts, while others live in rainforests, temperate forests, grasslands, lakes, ponds, rivers, swamps and coral reefs. Some turtles, particularly the wide-ranging sea turtles, have huge ranges that span thousands of miles. By contrast, some species inhabit only a small geographic area or a particular body of water.
Some of the areas with extraordinary diversity include the rivers, lakes and streams of the southeastern United States, the rainforests of Southeast Asia, central Africa and the Amazon basin. The Galapagos Islands are home to the largest terrestrial species, Chelonoidis nigra, while southern Africa is home to the smallest species, Homopus signatus.
Turtles may eat plants, animals or both. While most have relatively flexible diets and will concentrate on abundant prey, some turtles and tortoises specialize on a particular type of prey. For example, snapping turtles may consume ducks, plants, birds, snakes, fish, insects or other turtles, while the hawksbill turtle primarily consumes immobile animals called sponges.Learn More
The greatest human leapers in the world are able to jump over a bar suspended nearly 8 feet off of the ground. While the world record consistently increased for a period of about 100 years, recently, it appears that competitive high jumpers may be approaching the human body’s biological limits. Most average humans jump only a fraction of this height.Full Answer >
Diatoms and dinoflagellates are both types of phytoplankton that live in oceans throughout the world, but they contain unique physical characteristics that make them easy to distinguish from one another. Diatoms and dinoflagellates fall into the broad category of phytoplankton. These two groups are the most common of all phytoplanktons and have single cells but vary in body size and shape.Full Answer >
Index fossils are fossils that are found often in many different areas of the world. These types of fossils help to date other fossils that have been found in the same sedimentary layer of the Earth.Full Answer >
Scientific names are important because they allow people around the world to communicate accurately about animal species. With the help of international rules on naming animals, zoologists avoid naming the same species twice. This means that each scientific name is unique.Full Answer >
