It might surprise you to learn that humans aren’t the only animals that grow their own food. From leaf cutter ants cultivating underground fungi farms to fish harvesting crops of algae, check out these eight amazing animal agriculturists.

When it comes to the king of gardeners, nobody can rival the leaf cutter ant. Collecting leaves to use as manure for their complex underground fungi farms, leaf cutter ants have been growing their own food for as long as 50 million years. Specialized workers called mediae forage around for plant material (they have been known to strip a citrus tree clean in a single day) which they lug back to the nest and hand to the minims who chew them up, compost them and feed to the fungi in one of the most elaborate forms of insect agriculture ever documented.

Bowerbirds and their potato bushes are the first known example of the cultivation of a nonfood plant by a nonhuman species. They construct elaborate nests, also known as bowers, from twigs which they then decorate with various objects to attract the females. One of the most desired object by females is the purple berry of the potato bush; the more berries the male features on his bower, the better his mating success. As males don’t tend to build their nests in areas where the berries grow, they throw the disheveled berries outside the nest and by the time the bower is a year old they usually have a few dozen bushes growing nearby, giving them more opportunity to impress the ladies.
3. Ambrosia Beetles

Carving tunnels into decaying tree trunks, the ambrosia beetle carries fungi in special receptacles on their bodies and deposits the spores into handbuilt chambers where the fungi grows by drawing nutrients from the wood. The beetles carefully tend to their crops and once their larvae are fully grown, they fly off to bore into new trees and restart the process.

Termites are famous for having one of the most complex social systems in the animal kingdom. While they may be incredibly small animals, colonies are able to work together to create huge nests which are amazingly precise fungus growing farms. They create chambers which have the perfect amount of heat and airflow required to grow fungus, which is their primary food source.

As the only known fish to engage in agriculture, the damselfish are extremely protective over their gardens. Growing a variety of algae which is notoriously weak compared to other species, and one that only seems to survive within the territories of the damselfish, these loyal tillers work hard to ensure their favored food is kept for them and them alone. These feisty fish have been known to attack other creatures that dare to swim too close, including human divers.
6. Marsh Snails

Marsh snails are another fungus farming animal who have developed a way of ensuring that a readily available food source is never far away. Living in abundance in the Southeastern United States, these small mollusks encourage fungal growth on dead cordgrass leaves by cutting grooves into them with their radula. Having created the perfect growing environment for their favorite fungi, some marsh snails have also been observed fertilizing the leaves with their feces.
7. Spotted Jellyfish

The spotted jellyfish is an expert algae farmer which uses its own body tissues as the growth chamber. During the daylight hours, they spend the vast majority of their time orientating themselves in the best way to catch the most amount of sunlight. The photosynthetic crop flourishes inside their internal gardens, giving the jellyfish an unlimited supply of fresh algae to consume.
8. Yeti Crab

Not everyone needs a garden to grow their own grub. Yeti crabs choose to farm their food on their own arms! Video taken by submarine revealed the crabs dining on bacteria dwelling on their arms by using highly specialized hairy mouth appendages. Known for waving their claws slowly and rhythmically, scientists first thought this behavior was a tactic employed to keep others at a distance, but we now know that the claw swaying helps to wash nutrients over the bacteria, essentially fertilizing them.
