Turns out it wasn't the doing of aliens who'd overshot a Nebraska cornfield or out-of-work art students with scuba gear. No, it was a masterwork by an amorous and talented male Takifugu rubripes, the poisonous pufferfish eaten by only the bravest sushi connoisseurs.
Yoji found a series of small male fish working tirelessly, day in and night out, to craft these mate-attracting marvels using a single fin.
ff the coast of South Africa, Cape Gannets spot their targets from the air and dive like a squadron of bombers to pursue their prey. A Cape Gannet can snap up a fish before it realizes it's even being chased. Photographer Alexander Safonov is astounded as he watches these amazing birds dive 25 feet (8 meters) underwater to catch a meal from a school of sardines.
"Cool" is finding out that dolphins are among the handful of species on Earth that can recognize themselves in the mirror. "Cooler" is finding out that dolphins "name" themselves from a young age with a signature whistle used to signal their identity to other dolphins.
Squid, it seems, may be among the most vulnerable, with consequences that could trickle through the marine ecosystem. A new study published May 31 in the journal PLOS ONE finds that squid raised in more highly acidified ocean water hatch more slowly and are smaller when they hatch than squid raised in ocean water at today's pH levels. The acid-exposed squid also have abnormal statoliths, which are internal, calcified structures that function like the mammalian inner ear to help squid keep their balance and orient themselves.
