Strange rain:One day in 2005,people in a small town in Serbia looked out their windows and saw an unusual sight.It was raining frogs!Surprisingly,they found their streets filling with the little jumping animals.Scientists thi...
My research specialty is in the biomechanics of locomotion–how organisms use their bodies to get from one place to the next (through walking or swimming, for instance). We can learn a lot about an animal by studying their locomotion, such as why their body is shaped the way that it is...
You see animals like frogs, snakes and bears they fall into a deep sleep during winter! Their bodies slow down to save energy! They don't eat! And they depend on their fat(脂肪) to live.Some animals store(储存) food in their houses! They don't sleep all winter, but they move muc...
The Fat-Tailed Dwarf Lemur is notable for being theonly primate known to undergo true hibernation. During the dry season, which can last up to seven months, these lemurs hibernate in tree hollows or other secluded spots. The fat stored in their tails before hibernation provides the necessary e...

Another good way to avoid the cold is to sleep through it.Many animals hide during the winter.Their bodies slow down.They save their energy (精力).They do not eat.They depend on their fat (脂肪).They do this until food returns.We call this hibernation (冬眠).S...
They do not eat. They live off their fat. They wake up when the weather gets warmer. We call this hibernation (冬眠). Snakes, frogs and bears hibernate in winter.Many animals stay active in winter and adapt to (适应) the cold weather. Some animals save food in...
that drastically alter aquatic bodies such as rivers and streams and ponds. Beavers take sticks, reeds, saplings and branches, and they use mud as a caulking material to build their dams. Beavers tend to build their dams in summer and fall, so be on the lookout for these impressive ...
Sexual dimorphism in Leptodactylus frogs: the males have bulging upper arms to (I am assuming) help them hold onto females during amplexus (grasping in mating competitions). Did I forget that Leptodactylus has big flanges on the humerus in males, to support those muscles? Seems so. An early...
