位于佛罗里达湿地的大赛普里斯沼泽里，孵化中的短吻鳄破壳而出。当小鳄鱼出壳遇到麻烦时，母鳄会用它长着两排利齿的颚，以令人难以置信的细致程度相助。

website: http://www.nationalgeographic.com/ From 33 founders in 1888, to a worldwide team today of thousands of dedicated individuals, National Geographic stands at the forefront of exploration, research, and scientific discoveries. The results educate people everywhere, helping them consider today's ever changing world and their place in it. Philanthropic support is critical, propelling projects and expeditions that inspire us all to care about the planet. The National Geographic Society has supported and chronicled the achievements of renowned explorers and researchers for more than a century. In doing so, the Society developed many related programs for grant-making, scientific research, education, and public outreach. In 1996, these diverse programs were organized under a single banner—Mission Programs—recognizing that all the efforts were focused on the same core mission: to increase and diffuse geographic knowledge while promoting conservation of the world's cultural, historical, and natural resources. These core scientific and education programs operate behind the scenes of the more recognizable arms of the National Geographic, from the Yellow Border magazine to the National Geographic Channel, providing additional media content.
