电光火石般的繁殖舞蹈
2023-01-02

一个巨大的海星在水中产卵，它正晃动着触须，摇曳着躯体，跳着电光火石般的繁殖舞蹈。海星在产卵时，上升和摇摆的“舞蹈 ”姿态有助于释放卵子和精子，并将它们摇入水流中，利于卵子在水中一起受精。

最浪漫的交配姿式
2023-01-08

对许多青蛙来说，最浪漫的交配方式就是长时间的拥抱，照片中哥斯达黎加的两只红眼树蛙正在交配。繁殖期开始，为了使卵受精，雄性会向雌性扑去并紧紧抱住。在动物王国，这样特殊的“粘人”行为有助于提高繁殖成功率。

CANYONLAND GROTTO, UTAH

A vaulted grotto with a skylight shelters the ruins of cliff dwellings. The Anasazi, or Ancient Ones, tilled corn in the valley below and retreated to the heights at night. Whether fleeing enemies or a prolonged and widespread drought, they disappeared from Utah by about 1300. This canyon, near Salt Creek in Utah's Canyonlands National Park, also shows evidence of disastrous flash floods at that time. Visitors today know the huge alcove as Paul Bunyan's Potty.

TREE FROG TADPOLES, COSTA RICA

Within days of being deposited on a leaf overhanging a stream, tree frog eggs grow into recognizable tadpoles. Bulbous yolk sacs provide nourishment. As the wrigglers develop, the gelatinous outer membrane decomposes, perhaps triggered by a chemical change in the tadpoles. One by one, they slide off to a life of their own in the water.

BIOLUMINESCENT ORGANISMS, JAPAN

The transparent shells of tiny Cypridina hilgendorfii, found in the coastal waters and sands of Japan, hold a creature that emits a luminous blue substance when disturbed. During World War II, the Japanese harvested these creatures for soldiers to use when reading maps and messages at night.

CHATEAU GAILLARD, LES ANDELYS, FRANCE

A symbol of long-ago battles, Chateau Gaillard lies in ruins near the town of Les Andelys, France. It was built by Richard the Lion-Hearted—King of England and Duke of Normandy—as a strategic redoubt against the king of France. In 1204 French soldiers storming the castle broke England's grip on Normandy.

ROCK CARVINGS, PETRA, JORDAN

Hidden at the end of a long ravine, the buildings of Petra, Jordan, were carved into sandstone cliffs by the Nabataeans around 312 B.C. After annexation by the Romans in A.D. 106, the city—once a hub of commerce—became less important as trade routes developed along the Red Sea and Nile River. Petra is now protected as a World Heritage site.
