Killer Whale
Killer whales, or orcas, although they are named so, are an aquatic mammal that is the largest member of the dolphin family. The killer whales are so named because of ther voracious appetite for fish, seabirds, sea turtles, and aquatic mammals. Killer whales scientific name Ordnus orca is derived from the Latin word orcas, meaning ‘cask’ or ‘barrel’, referring to the animal's broad, rounded shape. Killer whales have bold black-and-white color. The animals are glossy black over most the body, with a white belly and striking white patches above the eye.
Killer whales exist in more parts of the world than any other aquatic mammal. They inhabit all the oceans, both in the open ocean and dose to shore. They are more commonly found in colder waters, but they also occur in the warmer waters of the Bahamas, the Caribbean, and Hawaii. Killer whales have even been seen in some rivers, including the Louire and Seine rivers in France, the Elbe River in the Czech Republic, and the Columbia River in the western part of the United States.
Scientists fear that a number of human-created problems threaten killer whales.
Some killer whales have been captured from the waters around Japan and Russia for pubic display. Scientists suspect that widespread pollution, including chemicals in the oceans from agricultural run off and oil spills, have damaged the ocean habitats in much of the killer whale’s range. Fish and other prey absorb chemical contaminants into their bodies, and killer whales feed on these contaminated animals. As a result, the number of killer whales debilitated by diseases has increased. In the Pacific Northwest, pollution and over fishing have reduced salmon populations, limiting the availability of favorite killer whale preys. (Adapted from Microsoft Encarta, 2006)

Seahorses
Seahorses are strange-looking sea creatures with heads like horses. They are actually fish. They make their homes in warm, shallow waters, where they live amongst sea plants.
Just like a fish, a seahorse has a skeleton, gills, and fins. Unlike other fish, however, it does not have scales. Its body is covered with bony plates of ‘armour’. This heavy ‘armour’ makes it hard for the seahorse to swim. It spends much of its time resting among the sea plants. It uses its prehensile tail to anchor itself to the plants. When microscopic sea animals swim by, the seahorse quickly sucks them up with its long snout.
The eyes of a seahorse do not look straight ahead like ours. A seahorse can look left with one eye and look right with the other. This means it can look out for enemies with one eye and search for food with the other.
Seahorsesarecleverat camouflaging themselves. They come in many colors. They can be brown, red, yellow, black, gray, or white. They can also change their colors in the blink of an eye. This makes it hard for enemies like birds and crabs to see them.
The most unusual thing about seahorses though, is that male seahorses give birth! The male seahorse has a pouch below his belly. The female places 150 to 200 eggs in this pouch. The male will then fertilise the eggs. He keeps them safe until they become fully formed baby seahorses. Baby seahorses must look after themselves as soon as they are born.
In many parts ofthe world, seahorses face danger. Pollution destroys their homes. People in some Asian countries capture seahorses to make medicines. In North America, many people like to catch and keep seahorses in aquariums as pets. Nowadays, however, there are seahorses 'farms’ which help provide many seahorses for aquariums.
Let us hope that in future, humans will do more to protect these amazing little creatures.
