Dusky Dolphins

Dusky Dolphins (Lagenorhynchus Obscurus) is very closely related to the Pacific White Sided Dolphin although studies show these are two different species of dolphin.
These dolphins are small and easy to identify, due to the head which is evenly sloped. It also lacks a beak at the end of its snout. On their tails and along their back is a bluish black color. Their belly is white with a dark color on the lower jaw and snout. Dusky Dolphins can grow to 6 1/2 feet long and can weigh anywhere from 150 to 187 pounds. The males and females look about the same size, though the males have a more curved dorsal fin. Dusky Dolphin have about 24 to 36 pairs of teeth which are pointed and very small. Usually, the upper jaw will have two sets less teeth than the bottom jaw. These dolphins are very social, and live in pods of about 20 to 500 members.
Dusky Dolphins are very acrobatic and jump out of the water very often, such as in the picture above. They feed on shrimp, squids, various fish and anchovy. It is hard to get a total or around the amount of number of the Dusky Dolphin species, though it is known that many of them die, getting caught in fishing nets or illegal harpoon hunting. Right now though they aren't in danger of becoming extinct.

The Tiger is the largest big cat. They are also the most powerful cats too. As you see in the picture, tigers are orange, sometimes white with black stripes. Tigers are the only big cat to have stripes. Their stripes help them camouflage into their surroundings. Tigers eat deer, cattle and wild boar. They also eat snakes, buffalo, leopards, camels, and sometimes crocodiles. Their only predators are humans (to an adult). Unlike other cats, tigers love the water. Though it depends. Some species of tiger would spend hours in the water, swimming in it and splashing around. But other s, like the Amur Tiger would only take a sip of water and then they would leave. Personally, I love tigers.

Peregrine Falcons

Peregrine Falcons are the fastest animals in the world! Adult Peregrine Falcons can reach speeds of 390 km/h. But they can only reach this speed in when they dive. These birds are found everywhere except New Zealand and the Arctic/ Antarctica.
At one point, Peregrine Falcons almost went extinct because of something called DDT. It was an insecticide. When a Peregrine Falcon digested it, a female would lay eggs with very thin shells. These birds are now making a comeback but can still be killed off. We need to protect these birds.
Why? Because they almost went extinct. They are okay now but they are still endangered.

      Lions may be the only wild cats that are social. A group of lions are called prides. One group of lions can have up to 40 members. Lions are referred to as "king of the jungles." Lions are carnivores. They eat zebra, antelope and wildebeest. Asiatic lions eat goats and buffalo. Male lions have manes. The bigger and darker the mane, the more likely females will mate with him. The mane also protects the neck of a male lion when he fights with other males. The lions closest relatives are the tigers, snow leopards, jaguars and leopards.
