American alligator -

The American alligator can lay 20 to 50 eggs in a single clutch. These eggs are buried in a nest of vegetation, which provides heat during incubation. Despite the large number of eggs, many hatchlings fall prey to predators in their early life stages.

Atlantic cod -

Atlantic cod are known to release between three to nine million eggs during spawning. These eggs are spread throughout the ocean currents. While most don’t survive to adulthood, this high reproductive output ensures the survival of the species.

Norway lobster -

The Norway lobster, a marine crustacean, can carry up to 20,000 eggs on her abdomen. These eggs hatch into larvae, which develop in the ocean before growing into adulthood.

African driver ants -

African driver ants, also known as army ants, can give birth to up to four million offspring in a single reproductive event. The queen ant, whose sole purpose is reproduction, continuously lays thousands of eggs each day to maintain the colony's vast population.

Atlantic bluefin tuna -

Atlantic bluefin tuna are prolific spawners, with females capable of producing up to 30 million eggs in one reproductive season.

Atlantic herring -

Another fish from the Atlantic Ocean, herring are known to spawn millions of eggs during their breeding season. A single female can lay between 30,000 to 200,000 eggs, which are fertilized in the water.

Cane toad -

Cane toads are notorious for their incredibly high reproductive rate. A single female can lay up to 30,000 eggs at one time, which are laid in water. Within days, they hatch into tadpoles that spread out through waterways.

Common octopus -

The common octopus can lay up to 100,000 eggs during one reproductive event. The female carefully guards these eggs until they hatch, although she typically dies shortly afterward.

Seahorse -

Seahorses are one of only two creatures on the planet where the male gives birth, the other of which is the sea dragon. The female inserts its eggs in the male’s brood pouch, and when he gives birth the male spews 2,000 of its offspring out like a cannon.

Axolotl -

The axolotl, a unique salamander native to Mexico, is known for its remarkable ability to regenerate limbs and organs. It remains in its aquatic, larval stage throughout life, reproducing without undergoing metamorphosis. Axolotls typically lay around 100 to 1,000 eggs.

Tsetse flies -

Tsetse flies, although small in size, are capable of giving birth to numerous offspring throughout their three-month lifespan. A female can produce an average of 30 to 40 larvae in her lifetime.

Dungeness crab -

Female Dungeness crabs can carry up to 2.5 million eggs under their abdominal flap after mating. These eggs hatch into larvae, which then float in the ocean as plankton before maturing. Despite the large number of eggs, many offspring don't survive to adulthood.

European eel -

The European eel lays between three to 10 million eggs during its spawning migration to the Sargasso Sea. These eggs hatch into larvae that make an extensive journey back to European rivers where they grow into adults over several years.

Green sea turtle -

Green sea turtles lay between 80 to 120 eggs per clutch, with some females laying up to seven clutches during the nesting season. These eggs are buried in sandy beaches, and only a small percentage of the hatchlings survive the perilous journey to the sea.

Green iguana -

Green iguanas lay clutches of 20 to 70 eggs in underground nests. After laying, the female interestingly leaves the eggs to incubate independently.

Mola -

The mola, or ocean sunfish, is perhaps the most fertile animal on this list! Not only is it the world’s heaviest bony fish, but it is also a heavyweight egg producer. One mola can release up to 300 million eggs over a spawning season!

Lionfish -

Lionfish are prolific breeders, capable of laying up to 30,000 eggs every few days. This reproductive success has contributed to their invasive spread across the Atlantic, where they pose a significant threat to native marine ecosystems.

Atlantic horseshoe crab -

Female Atlantic horseshoe crabs lay thousands of eggs, often depositing between 60,000 to 120,000 eggs in sandy beaches during spawning season. These eggs provide a vital food source for migrating birds, and only a few reach adulthood.

African termite -

The African termite queen can produce tens of thousands of eggs each day, sometimes laying around 30,000 to 40,000 eggs daily.

Nile crocodile -

Female Nile crocodiles lay between 25 and 80 eggs in a clutch, which are carefully guarded by the mother. Despite this parental care, many young crocodiles fall prey to predators before reaching adulthood, which maintains a balanced population.

African clawed frog -

African clawed frogs can lay up to 2,000 eggs in a single clutch, which are fertilized externally in the water. These eggs quickly hatch into tadpoles and develop into frogs within weeks.

Komodo dragon -

Komodo dragons typically lay 15 to 30 eggs at a time. The mother digs a nest to protect the eggs, but once laid they receive very little parental care. The hatchlings face numerous challenges from predators and even adult Komodo dragons.

Australian freshwater crayfish -

Australian freshwater crayfish, like other crustaceans, are capable of producing large numbers of offspring. A female can carry hundreds of eggs on her body, with these eggs hatching into free-swimming larvae before developing into juvenile crayfish.

African wild dog -

African wild dogs typically give birth to litters of six to 10 pups. While this number is low compared to most on this list, these carnivorous animals work together as a pack to care for their young, ensuring that most of the pups survive to adulthood.

Opossum -

Opossums are marsupials that can give birth to litters of up to 20 joeys at a time. However, only a few manage to survive, as the mother has limited teats for nourishment and the competition for survival begins as soon as they are born.

Arctic fox -

Arctic foxes typically give birth to litters ranging from five to 10 pups. Their large litters are an adaptation to their harsh environments, ensuring that enough offspring survive the cold and predation to continue the species' survival in extreme climates.
