Octopuses can see polarized light, but cannot see . However, their skin
Everyone knows sharks are fierce predators. How exactly they hunt so well is in part due to their extra sixth sense: electroreception! Exactly how sensitive are the ampullae of Lorenzini? By measuring brain activity, scientists can test how large electrical changes have to be for a shark to notice. They found that sharks can sense

Like us, they need to sleep, which — for us — involves almost total unconsciousness and paralysis. So how do these marine mammals not drown when they sleep?
The jewel wasp’s venom is potent on two levels. With the first stab of its stinger, the wasp paralyzes the much larger cockroach. The neurotransmitter GABA, inserted into the thorax of the cockroach, causes temporary paralysis by shutting down motor neurons. The paralysis allows for the second stab — a perfectly targeted attack on a specific
