  • A marine biologist snorkeled with a great white shark, even touching it. She called it “magic.” Others call it risky behavior and tell you to please not try it. Story and video, Washington Post.
  • An anomaly in our age of global warming, a deep region of the Pacific Ocean is actually cooling. It’s because of the very slow churn of the Great Ocean Conveyor Belt; the water in question was chilled during the Little Ice Age that lasted from the 1500’s to about 1840 AD. Popular Mechanics.

  • Spain, Mexico, Japan, and China are among countries where octopus farming is being envisioned. It might be good for calimari lovers but bad for the environment and the octopuses, scientists say. Science Daily.
  • One effect  of warming oceans brought on by climate change is that fish may get faster. Higher temperatures can make both the bodies and brains of cold-blooded fish work somewhat faster. The same presumably won’t be true for the warm-blooded birds and marine mammals that hunt them.
