题目Some people say dolphins(海豚)are smart like humans(人类).They can think,understand and learn things quickly.In fact,dolphins have big brain(大脑)-to-body size ratio(比例),which is second only to humans.Dolphins use brains differently from the way humans do.But...
aIn reality, dolphin and porpoise have a brain size that is much bigger than human's brain;however,human's brain is the biggest relative to body size in the whole animal kingdom. ( Save whales from sonar pollution, bycatch, trawling, and commercial fishing and let there be harmony) 实际...

we do not know the intricacies of the dolphin’s brain. It has two hemispheres just like the human brain. However, theirs split into four lobes instead of three. The fourth hosts all of the senses, whereas in humans, they are in different parts. Some believe that having all of the sens...
What are the key differences between human brains and dolphin brains? One difference is that dolphin brains have a relatively small prefrontal cortex and a smaller hippocampus. These smaller areas on the brain lead to dolphins having less higher-level thinking and memory when compared to humans. ...
46. The brain of dolphins is the second largest ratio between size compared to its body size; only behind humans. 47. It is possible for a mature dolphin to eat up to 30 pounds of fish per day. 48. Some dolphins can leap up to twenty feet in the air. ...

大脑大小必然与整体体型有关,大动物大脑大,小动物大脑小。然而,无论“智力”一词是如何定义的,一个物种仍有必要存在一些最低数量的电路(脑细胞和过程),以具有高度智能的潜力。一种适用于各种物种的相对大脑大小的测量方法是脑商(EQ),即大脑质量与身体大小的比率。EQ是通过测量来计算的不同物种不同身体部位的相对...
Human fishing is also threatening the species. Overfishing is a problem because it decreases food supply. The dolphins also get caught in the nets. Pollution is another threat. Small gold mining operations cause mercury pollution, and this makes its way to dolphins through the food chain. River...
However, their numbers are known to be drastically declining throughout the southern hemisphere, primarily due to the increasing levels of human activity in their native environments. Despite hunting them being banned, they are still caught in nets and trawlers by the thousands on a yearly basis....
