Spotted garden eels live in colonies of up to several thousand individuals. They spend the majority of their lives with only the top half of their body sticking out of a burrow they make in the sand, eating plankton and other tiny animals that float by. If in danger, the entire “garden” retracts into the sand in the blink of an eye.
Ants are excellent collaborators with others in their colony. Because they have the same biological urges (like following a trail of pheromones to food, then carrying the food home), ants will instinctually work together to accomplish larger tasks at hand.
