This is the second page of all about animals.
Rodents
More than a third of all the worlds mammals are rodents.From the pygmy jerboa, which could fit into a matchbox,to the capybara,which grows to 4ft (1.25m) long and weighs 110 lb (50 kg), rodents live in almost every envirment, from the artic to the desert. Some species spend almost all their lives in trees, while others live under ground.Several species, including beavers, spend much of their time in water.Rodents have many predetors. few species apart from porkypines can defend themself, and most produse large numbers of young to ensure the servival of their species.Rodents incisor,or front, teeth grow constantly,ready to knaw into hard- shelled nuts, treebark or other plant food.Some rodents eat insects and other small animals as wel as plants.Others have special diets-bamboo rats,for example,feed almost exclusively on bamboo.Harvest mice eat grain and seeds and builds their nests in long grass or fieldsof wheat.People in ancient Rome and in China once cooked and ate harvest mice as snacks!
Eagles
Like you an eagle sees because light hits light-sensitive cells at the back of the eyes. These cells send messages to the brain.Also, like you, eagles have two foward-facing eyes.(some animals have eyes at each side of their head, which means they can't look at the same object all at once.) So the brain recives two sets of overlapping messages. When it analyzes these messages, the eagle three- dimentinal image of the world. That lets it judge how far away somthing is. That way the eagle can pinpoint the exact location of its prey.
Platypuses and Echidnas
The Australian platypus, the short-beaked echinda of Australia and New Guinea, and the New Guinea long-beaked echinda are monotremes. These very primitive mammals have many reptiles features, such as a cloaca, which is used to get rid of body waste and to lay eggs. These mammlas ooze milk for their young from special patches of skin. Male platypuses and echindas have a long spur on each hind leg. In platupuses , this is connected to a venom gland and this is used in fights between males. Special organs in the rubbery skin of platypus's bill can detect the muscle activity prodused by its prey of shrimp, freshwater crabs and other invertebrates. Echindnas may olso beable to detect their prey in this way.
