The fact that only one pocket shark has ever been reported from the Gulf of Mexico, and that it is a new species, underscores how little we know about the Gulf."

The big picture: Scientists collected the male kitefin shark in 2010, the university said in a statement this week. The luminous specimen stood out among others when a National Oceanic and Atmospheric Administration researcher observed it in 2013, and the new species was later confirmed.

• It is only the 3rd known shark species out of more than 500 that may squirt luminous liquid, R. Dean Grubbs, a Florida State University scientist who was not involved in the research, told AP.

• "With whole new industries at stake, the race to unlock the secrets of the animal mind is getting weird," Bloomberg writes.

What's happening: Married Harvard neuroscientists Mackenzie and Alex Mathis record the decision-making activity of mice playing tiny video games, for instance. And Drew Robson and his partner, Jennifer Li, study zebra fish, a type of minnow whose bodies are transparent when they’re young, which allows researchers to observe their neurons at work.

• The pair uses a special mobile microscope they developed to record which neurons are active while the fish swim, adapting to changing conditions.
• It's similar to the way their Tesla's driving skills evolve with each Autopilot software update, Robson tells Bloomberg.

The bottom line: AVs need better artificial intelligence to advance beyond basic object recognition to human-like decision-making. They might learn a thing or two from mice and fish.
