下面是蓝鲸（blue whale ）的一些英文资料
The blue whale is the largest mammal,possibly the largest animal,to ever inhabit the earth.Its body is long,somewhat tapered,and streamlined,with the head making up less than one-fourth of its total body length.Its rostrum (upper part of the head) is very broad and flat and almost U-shaped,with a single ridge that extends just forward of the blowholes to the tip of the snout.Its blowholes are contained in a large,raised "splash guard",and the blow is tall and straight and over 20 feet (6 meters) high.Its body is smooth and relatively free of parasites,but a few barnacles attach themselves to the edge of the fluke and occasionally to the tips of the flippers and to the dorsal fin.There are 55-68 ventral grooves or pleats extending from the lower jaw to near the navel.
The blue whale is blue-gray in color,but often with lighter gray mottling on a darker background (or with darker spots on a lighter background).The underside of its flippers may be a lighter color or white,while the ventral (underside) of the fluke is dark.The blue whale acquires microorganisms called diatoms in the cold waters of the Antarctic and North Pacific and North Atlantic which give the underside of its body a yellowish green caste.Because of this yellow color,the early whalers gave it the name "sulfur bottom."
The longest blue whale ever recorded was a 108-foot adult female caught during whaling efforts in Antarctica!In modern times,blue whales in the Southern Hemisphere reach lengths of 90-100 feet ,but their Northern Hemisphere counterparts are smaller,on average 75 to 80 feet (23 to 24.5 m).Blue whales can weigh over 100 tons (99,800 kg).Females are larger than males of the same age,the largest perhaps weighing as much as 150 tons (136,000 kg).
The blue whale is thought to feed almost exclusively on small,shrimp-like creatures called euphausiids or krill.During the summer feeding season the blue whale gorges itself,consuming an astounding 4 tons (3.6 metric tons) or more each day.This means it may eat up to 40 million krill a day.As a baleen whale,it has a series of 260-400 fringed overlapping plates hanging from each side of the upper jaw,where teeth might otherwise be located.These plates consist of a fingernail-like material called keratin that frays out into fine hairs on the ends inside the mouth near the tongue.The plates are black and measure about 20 inches (51 cm) in length toward the front of the mouth and about 40 inches (102 cm) at the rear.During feeding,large volumes of water and food can be taken into the mouth because the pleated grooves in the throat expand.As the mouth closes water is expelled through the baleen plates,which trap the food on the inside near the tongue to be swallowed.
