Becoming a parent brings out the best in many animals. Although parenting is usually left to the females, males from many species go above and beyond to care for the offspring. Take anemone fish (海葵鱼) for example. In finding Nemo, Marlin swims over 1,000 miles from the Great Barrier Reef to Sydney to rescue his son Nemo, who has been caught by divers. In reality, anemone fish rarely move so far away from their home.
Despite their smaller size, the males help the females defend the nest, but only the male anemone fish take care of it. They use their fins as fans to provide a constant flow of oxygen and keep the surroundings clean. They also put a lot of effort in building the nest.
The eggs take about five days to hatch. During this important period, dads fan them to provide oxygen and remove the rubbish. They also pick up the eggs in their mouths and move them around to remove any bacteria. One of the biggest threats comes from female sticklebacks (刺鱼), who form organized groups and attack the nests to eat all the eggs.
Males defend the newborn fish and bring back the ones who move too far from the nest. Once the fish grow up, they become a little bit more independent and start to swim away. The dad swims after them, picks them up in his mouth, and spits them back into his nest. Eventually, he gets to the point where he can't keep track of them and that's when they separate.
Doting (溺爱的) fathers are not restricted to the world of fish. In some poison frog species, the dads also warn the moms when the young ones are hungry and need to be fed. It's generally believed that moms are the caregivers. In fish and frogs, it's actually more common for the dads to provide care.
