How did the sea horse get its name? It’s not hard to guess. The top half of this fish looks like a small horse. But looking at the sea horse’s tail, you might think “sea monkey” is a better name. Then there’s the sea horse’s pouch (口袋). “Sea kangaroo” might also be a good name for this fish.

Sea horse live in warm ocean waters all over the world. They keep safe from other fish by hiding in plants and grasses that grow under the sea. They can also change colors to match their surroundings (环境). A sea horse in one place for hours at a time by winding its tail around a plant. It feeds on live food, such as small shrimp (虾). For a fish that doesn’t move around much, the sea horse eats a lot—in just one day, a sea horse can eat 3,000 shrimp!

A sea horse keeps the same mate for its whole life, and it’s the male (雄性的) sea horse that gives birth to baby sea horses. How does this happen? Baby sea horse start out as eggs, which come from the female’s (雌性的) body. The male carries the eggs in its pouch for about three weeks until they hatch (孵化). Soon after the babies are born, the female gives her mate a new set of eggs.

Sadly, the number of sea horses is becoming smaller. Why is this happening? Some places where sea horses once lived have been filled in to make new land. Also, many sea horses are caught and sold as aquarium (水族馆) fish. This really is not a good idea because most sea horses don’t live long in aquarium. The best place for a sea horse is the ocean.

文章大意:本文是新闻报道。文章报道了关于中国长江白鲟灭绝的消息,介绍了这种大型淡水鱼的历史、现状以及导致其灭绝的原因。

【推荐1】The Chinese paddlefish (白鲟) living in the Yangtze River was declared extinct (灭绝的), according to a paper from Chinese experts at the Yangtze River Fisheries Research Institute.

The Chinese paddlefish is one of the world’s largest freshwater fishes, which can grow up to 7 metres long. People call it “the Giant Panda of Rivers” because it is rare and native to China under first-level national protection, and its ancestors date back to more than 100 million years ago.

From the middle of last century, the population of the Chinese paddlefish declined rapidly due to overfishing, habitat degradation (毁坏) and pollution. The construction of Gezhou Dam in 198l on the Yangtze River also created a barrier to the migrating (迁徙) fish, contributing to the sharp decline of it.

【推荐2】In September 2019, a man named Anuchit was riding his motorcycle down a highway in Thailand. He spotted a sad-looking dog sitting on the side of the mud. The poor dog seemed to be waiting for someone.

Later that day, Anuchit rode by that exact same spot and found the same dog still sitting there.
