Kingdom: Animalia
Phylum: Arthropoda
Class: Insecta
Order: Hymenoptera
Family: Formicidae
Ants

Ants are insects from the Formicidae family. Ants are related closely to wasps and bees, and it's estimated that ants evolved from a wasp-like ancestor about 140 million years ago. Scientists believe that there are about 22,000 species of ants, but there have only been 12,500 species classified so far. Ants have three distinct body regions: a head, thorax (the middle section), and abdomen (the rear section), and have two long antennae.

Did you know?

  • If humans were as strong as ants, you could easily lift and carry a car or a fully-grown cow.

    Ants have strong, jointed legs that allow them to carry heavy loads, and their exoskeleton, or outer shell, provides extra support. They also have powerful mandibles, or jaws, that can grasp onto objects and hold them firmly in place. Because of these traits, entomologists estimate that ants can lift anywhere from 50-100 times their body weight.

    One study published in the Journal of Experimental Biology found that the Asian weaver ant Oecophylla smaragdina can lift objects up to 100 times their own body weight using their jaws. Similarly, the leafcutter ant Atta cephalotes can carry up to 50 times their own body weight, according to a study published in the journal Insectes Sociaux.

  • Instead of using lungs, ants breathe through small holes in their bodies.

    Ants have small holes in their bodies called spiracles that allow air to enter and exit. Through these spiracles, ants are able to take in oxygen, which they need to help their cells produce energy. They also release carbon dioxide, which is a waste product of cellular respiration. The spiracles are located all over the ant's body, including on the thorax and abdomen, and are connected to a network of tubes called tracheae.

    This system of air exchange allows ants to breathe without needing lungs, which would be too heavy and bulky for their small bodies. It also allows them to be more efficient in their use of oxygen, which is important for insects that have high energy demands.

  • Queen ants can live up to 30 years and can lay millions of eggs during their lifetime.

    Because the queen ant is the only ant that can lay eggs and create new ants, she is essential to the survival of the entire colony. If the queen ant dies, the colony may survive for a few months, but it will eventually collapse. Without her, the colony cannot produce new workers or soldiers, and it will eventually die off. It's lucky then, that queen ants can often live for many years.

    In some species of ants, such as the leafcutter ant, the queen ant can weigh up to 50 times more than the worker ants. She is also usually the largest ant in the colony and is often protected by the workers and soldiers. Overall, queen ants are a crucial part of ant colonies and play an important role in the survival and reproduction of their species.

  • Some of the fastest ants can run up to 106 times their body length per second.

    A recent study published in the Journal of Experimental Biology found that Saharan silver ants, Cataglyphis bombycina, are capable of running at a speed of 0.855 meters per second, which is about 108 times their body length per second. Cheetahs on the other hand, the fastest land animal, can only run at about 16 body lengths per second.

    Ants are able to run incredibly quickly because of their small size and the unique structure of their legs. Their legs are very strong and can move rapidly, allowing them to cover a lot of ground in a short amount of time. Some species of ants are even able to run upside down on smooth surfaces, which is an impressive feat.

  • Ants hear with their feet and can even use them to communicate with other ants.

    Ants don't have ears and instead use their legs to detect vibrations in the ground. They have special hairs called "sensilla" on their legs and feet that are sensitive to vibrations, allowing them to "hear" their environment. This unique characteristic of ants enables them to hear threats, locate food, and even communicate with each other.
