4. LEGS OF LOVE
The Pacific octopus doesn't hesitate when it comes to protecting her soon-to-be babies. Females lay thousands of eggs and then settle in for a long sit. A mother rests on her eggs for seven months, blowing currents of water over them for oxygen and protecting them from predators. Sadly, all this time babysitting prevents the Pacific octopus from hunting, so the mother passes away shortly after her children hatch.
