海豚这个名字我想大家听后肯定都很喜欢，这是因为海豚聪明灵敏，经过训练后还能表演呢!海豚虽然聪明灵敏,可是海豚在世界上已经非常稀少了，所以我们要保护海豚喔!

海豚作文。白海豚是迄今生存下来的最原始的海豚之一，是我国的珍稀动物。海豚不仅聪明而且也很听群体的命令，假如一只海豚游到了岸上的话，其他的海豚就会游到浅水区挨沙滩近的地方，到退潮时，海豚如果不能迅速返回大海，它们就可能死在海滩上。
海豚还能救人呢!不信的话，就让我来给你说说吧!一天上午，一艘战舰在行驶时，突然一个大浪打过来，把船给打沉了，海军战士们都落海身亡了，只有船长晕了过去。这时一只海豚把船长驮在它背上，一直游到了岸边，用最大的力气把船长甩上了岸，然后返回了大海。船长醒来后，看见海豚在那跳跃，知道是海豚救了他，他对着海豚行了个军礼。
海豚长了个长嘴巴，身子是黑色的，最有趣的是海豚的头顶上长着鼻子。我喜欢海豚这个样子。
记得有一次在香港，我和妈妈看了有趣的`海豚表演。海豚表演开始了，训练员把一只海豚从水笼子里放了出来。训练员发出命令后，海豚就跳出水面，然后可爱的海豚把身子和头探了出来，对着训练员叫。我想是海豚觉得自己的表现很好，想让训练员喂它东西吃，果真不出所料，训练员从口袋里掏出一只黄鱼喂给海豚吃。接着训练员就让我们出算术题。一个姐姐说四加五等于几，海豚从水里跳出来，用尾巴拍打水面，共拍打了五下。然后叫唤，训练员给我们解释，说海豚是问那个姐姐我的答案对吗?这真是一次有趣的表演。
我想让海豚能走，能说话，这可太好玩了。
