A common species of fish found throughout the world, stickleback dads are another example of single parents. In the spring, male sticklebacks build nests from algae, sand, and whatever else they can find, which they glue together using a protein called “spiggin”, formed in their kidneys. Spriggin takes A LOT of energy to make, and so after mating, the already exhausted dad must get even more exhausted because the lady leaves the eggs to his care and goes.
