A. A … (a bird of prey) has a hooked, sharply pointed beak. At the base is a waxy cere, through which the nostrils open. The feet are powerful with sharp claws. Large eyes, placed forward in the head, give good binocular vision. A large raptor can see an object from 3 to 8 times more distant than a human can see it. The sense of smell is poor.

B. A newborn young … weighs less than one gram. Born 36 days after mating, it climbs to the pouch and attaches to nipple, which swells to plug into its mouth. The female will mate again after giving birth, but until the embryo will not develop inside her. If the suckling baby disappears, the embryo will resume development.

Ostrich can stand up to 2.7 m tall and weigh 156 kg. The Ostrich has been used as a domestic farm bird since the 19th century. An Ostrich can swallow fruits up to 6 cm in diameter.

D. The …, the only remaining herbivorous mammal, which lives entirely in the sea, is found in shallow, warm coastal waters in Western Australia. It is related to the three living species of freshwater manatees, but its nearest relative was Stellar's Sea Cow, which was discovered by Europeans in the northern Pacific Ocean in 1741. This enormous animal, which weighed up to six times as much as its modern relatives, was hunted vigorously and became extinct by 1768. The Dugong's powerful tail can propel the animal at up to 22 kilometers per hour. Its paddle-like forelimbs are used for steering, feeding and pushing the animal along the seabed.
