A sea eagle, it has two known subspecies and forms a species pair with the white-tailed eagle (Haliaeetus albicilla). Its range includes most of Canada and Alaska, all of the contiguous United States, and northern Mexico. It is found near large bodies of open water with an abundant food supply and old-growth trees for nesting.The bald eagle is an opportunistic feeder which subsists mainly on fish, which it swoops down and snatches from the water with its talons. It builds the largest nestof any North American bird and the largest tree nests ever recorded for any animal species, up to 4 m (13 ft) deep, 2.5 m (8.2 ft) wide, and 1 metric ton (1.1 short tons) in weight. Sexual maturity is attained at the age of four to five years.Bald eagles are not actually bald; the name derives from an older meaning of the word, "white headed". The adult is mainly brown with a white head and tail. The sexes are identical in plumage, but females are about 25 percent larger than males. The beak is large and hooked. The plumage of the immature is brown.The bald eagle is both the national bird and national animal of the United States of America. The bald eagle appears on its seal.

2. With a top speed of five feet per hour, what is the world's slowest fish ?  

 

The dwarf seahorse (Hippocampus zosterae) is a species of seahorse found in the subtidal aquatic beds of the Bahamas and parts of the United States. It is threatened by habitat loss. According to Guinness World Records, it is the slowest moving fish, with a top speed of about five feet per hour (152 cm per hour). It is most often white in color but can range from tan, brown, yellow and green. In the wild, it often has small skin growths called cirri that resemble algae. Like other seahorses, the dwarf seahorse has a head angled at right angles to its body and swims upright using its dorsal fin to propel it and its pectoral fins to steer. It grows to a length of between 2 and 2.5 cm (0.8 and 1.0 in) and its color ranges from beige, yellow, green, and black. It may have white speckles, dark spots or protrusions and is well-camouflaged, the coloring usually matching the gorgonian on which it is typically found. It can change color.The dwarf seahorse is a lie-in-wait predator, feeding on anything of a suitable size that comes within reach.These fish are usually solitary or live in pairs. The males carry the developing young in a brood pouch for about ten days. Males maintain a small territory while females roam more freely.

3.All tigers,expect white tigers,have what color of eyes? 

 

The white tiger is a pigmentation variant of the Bengal tiger, which is reported in the wild from time to time in the Indian states of Assam, West Bengal and Bihar in the Sunderbans region and especially in the former State of Rewa. Such a tiger has the black stripes typical of the Bengal tiger, but carries a white or near-white coat.
The white Bengal tigers are distinctive due to the color of their fur. The white fur caused by a lack of the pigment pheomelanin, which is found in Bengal tigers with orange color fur. When compared to Bengal tigers, the white Bengal tigers tend to grow faster and heavier than the orange Bengal tiger. They also tend to be somewhat bigger at birth, and as fully grown adults. White Bengal tigers are fully grown when they are 2–3 years of age. White male tigers reach weights of 200 to 230 kilograms and can grow up to 3 meters in length. As with all tigers, the white Bengal tiger’s stripes are like fingerprints, with no two tigers having the same pattern. The stripes of the tiger are a pigmentation of the skin; if an individual were to be shaved, its distinctive coat pattern would still be visible. For a white Bengal tiger to be born, both parents must carry the unusual gene for white colouring, which only happens naturally about once in 10,000 births. Dark-striped white individuals are well-documented in the Bengal tiger subspecies (Panthera tigris tigris) as well as having been reported historically in several other subspecies.Currently, several hundred white tigers are in captivity worldwide, with about one hundred being found in India. Their unique white color fur has made them popular in entertainment showcasing exotic animals, and at zoos.
