According to Inside Science, studies have shown that common field ants can carry up to 5,000 times their body weight. An ant's strength is in its neck, as it contains multiple folds and bumps that allow for extra traction when carrying heavy loads.
In addition to their strong necks, ants possess a thicker cross-sectional area, in relation to their actual body size, that allows for additional strength when carrying food. Ants communicate with one another by releasing message-sending pheromones. Ant colonies consist of multiple ants, in which each ant has a specific job. Young ants tend to remain in the nest and work closely with the queen, while older ants work away from the nest, gathering food and protecting the colony from intruders.
