did you know? Dogs get high when you rub their ears real good. They have a branch of nerves in their ears that extend to their internal organs and release endorphins when you rub them, sending relaxing impulses through their bodies and giving them a natural high.
When male and female anglerfish mate, they melt into each other and share bodies, forever. The deep sea is so vast that if a male finds a female he latches on and fuses to her, losing his eyes and internal organs until the two fish share a bloodstream.
