Remotely Operated Vehicles or ROVs are military vehicles used for many scientific studies. A remote control vehicle (RCV) is an autonomous vehicle used for carrying out scientific research by means of a transmitter and camera on board. Most RCVs are amphibious and they can easily enter into water. These vehicles have a cylindrical body with a sealed interior consisting of several layers of fabric on the inside including carbon fiber and Kevlar. The exterior is usually painted with camouflage paint scheme.

These remote controlled vehicles: are used for a wide variety of functions such as sampling, tracking, locating, surveillance, rescue, and locating animals in remote areas. Many animals have lived in all parts of the world for millions of years. amphibious It is believed that amphibians are the first life forms on earth. They evolved from a more ancient ancestor called chordates.

Amphibians have an egg-laying process called hatching while fishes lay eggs internally where the embryo grows into a fish.

• Many reptile species are classified as dinosaurs.
• Dinosaurs are a class of mammals descended from the more distant ancestor of modern day reptiles.
• Unlike birds, most reptile species have a single set of pneumatic teeth to support chewing.
• They have neither hair nor hair follicles and do not produce hair along their tails or other parts of their bodies.

They lack a thick bone armor and are cold-blooded; being subsistent through a constant internal body temperature and food intake which provide them with an abundance of energy and allow them to move about. Other animals such as rodents and certain insectivores secrete chemical compounds that coat the exterior of their skins with waterproof coating. This chemical coating is what provides the animals with the resistance against hot and cold temperatures. Their scales also reflect light and are almost transparent. Many reptiles lay eggs that contain a complex chemical composition that allows the organisms to develop in the environment of the mother organism. The developing embryos develop inside of the eggs and hatch out to be either animals or people.

Some of the most fascinating aspects of REPTILES: are the amazing abilities they have developed to deal with the most basic of environmental stresses. The scales help prevent reptiles from losing water during the winter months. This ability to conserve moisture makes them even more interesting as breeding animals year after year. They can be bred in captivity to produce children who possess the same characteristics of their parents.

The most famous members of the REPTILES family: lizards and snakes are commonly studied by scientists all over the world. Many lizards like the Australian lizard named Scelidopus and the harmless cellar snake of the West Australian region. Snakes such as the coral snake and its smaller relatives such as the common king snake are popular pets.

Amphibians, too, play an important role in the study of the ecosystem and how living creatures interact with one another and with the environment as a whole.
