Southern elephant seals jousting off the coast of Anvers Island, near Palmer Station on the Antarctic Peninsula. Neither seal is hurt in this “ceremonial” fighting.
Adélie penguins, filmed near Palmer Station, on the Antarctica Peninsula. Biologist Bill Fraser has studied penguins in this region for 30 years. He has shown that the Adélie population has plummeted. When he first traveled to Palmer Station, in the 1970s, the ice floes and rocky outcrops near the U.S. research base were thick with the knee-high birds; and the constant, almost deafening roar of their calls made it impossible to hold a conversation. That population has shrunk by about 80 percent since he began studying it in 1974. He expects Adélies to be extinct in the region in a matter of a few years.
Monarch Emerges from a Chrysalis
Ever wonder how a chrysalis turns into a butterfly? I did. So I collected a few monarch caterpillars one summer to find out. The caterpillars attached themselves to leaves after a while. In a few days the caterpillars became chrysalises. After waiting more days, I saw the chrysalises turn from green to black. I later realized that the green shells had not actually turned black but had become clear, revealing black parts of the folded butterfly within. After some experiments, I discovered when a butterfly was about to emerge and I was ready to film it. The insect emerged quickly, then dried its wings off in the air. Soon it was ready to fly away. Please also look at my video of a caterpillar becoming a chrysalis.
Monarch Caterpillar Becomes a Chrysalis
Ever wonder how a caterpillar turns into a chrysalis? I did. So I collected a few monarch caterpillars one summer to find out. The caterpillars attached themselves to leaves after a while. Then after a few days, the caterpillar started twitching. I thought the process — whatever it was — would take a long time. It didn’t. As I watched and photographed, the skin of each caterpillar split and peeled off. Beneath the black, white and yellow caterpillar was the shinny green chrysalis. See my movie of a butterfly emerging from a chrysalis to see what happened next.
