I’ve seen lots of sharks when I’ve been on snorkeling excursions in tropical waters. It always feels a bit creepy to see them – afterall, these animals are top predators! (Maybe I remember too many of Gary Larson’s “natural selection” cartoons....?)
Whenever I visit the Monterey Bay Aquarium in California, I have to pry myself away from the cuttlefish, nautilus and octopus exhibits. The intelligence, curiosity, and unique body plans of these cephalopods mesmerize me. So it is a big thrill to see these creatures in their natural habitats.....
The faces of our ancient ancestors are fascinating. Andean art includes portrait head vessels of high-status men created by the Moche culture that flourished along the north coast of Peru some 2,000 years ago. There is careful rendering of nose shapes, chins and other distinctive details of appearance and personality.
Can you think of an animal living today whose relatives, some of them gigantic, ruled the seas for hundreds of millions of years – but then became extinct along with the dinosaurs? This survivor, the chambered nautilus (Nautilus pompilius), is little changed from ancestors that flourished more than 400 million years ago.
