Ants learn very rapidly, their memory lasts up to 3 days, decreases slowly over time and is highly resistant to extinction, even after a single conditioning trial. Using a pharmacological approach, we show that this single-trial memory critically depends on protein synthesis (long-term memory).
Ants don't have complex emotions such as love, anger, or empathy, but they do approach things they find pleasant and avoid the unpleasant. They can smell with their antennae, and so follow trails, find food and recognise their own colony.
Individual ants have tiny brains but together the many ants of a colony can exhibit remarkable 'intelligence'. Ants exhibit complex and apparently intelligent behaviour; they can navigate over long distances, find food and communicate, avoid predators, care for their young, etc.
Many have the doubt that “does ants have brain?”, yes, they do have brain and it is very small that have 250,000 neurons. It is very less compared to human brain, but it is too large compared to other insect species. These ants have thinking ability and they can follow their routine with their colony.
How Intelligent Are Ants? Ants are regularly labeled the most intelligent of all insects. Time magazine even declared “Your Ant Farm Is Smarter Than Google.” Yet some look down on ant intelligence, arguing that – due to the size of their brains – ants are not actually smart but just follow signals.
In 2015, scientists published research11 that suggests some ants can recognize themselves when looking in a mirror.
Ants, like other insects, have a heart that pumps hemolymph rhythmically.
Ants are similar to many other insects in that they possess senses such as hearing, touch and smell. Although hearing is very different in ants than animals that typically have ears, ants do possess the capability to hear.
In fact, there's mounting evidence that insects can experience a remarkable range of feelings. They can be literally buzzing with delight at pleasant surprises, or sink into depression when bad things happen that are out of their control.
Ant colonies have specialised undertakers for the task. They usually carry their dead to a sort of graveyard or take them to a dedicated tomb within the nest. Some ants bury their dead. This strategy is also adopted by termites forming a new colony when they can't afford the luxury of corpse carriers.
Even in a bustling ant colony, some workers stand around and do nothing. And yet, despite their generally industrious reputation, inactivity may be part of an ant colony's natural social structure.
A recent study of ants' sleep cycle found that the average worker ant takes approximately 250 naps each day, with each one lasting just over a minute. That adds up to 4 hours and 48 minutes of sleep per day. The research also found that 80 percent of the ant workforce was awake and active at any one time.
When the ants are crushed, a unique odor becomes detectable; some describe the smell as rotten coconut, others say it smells like ammonia. They are polygenic (multiple queens within one colony), which allows them to grow their colonies at an incredible rate; a single colony can have as many as 10,000 workers.
Depending on the type of ant that bit you, an ant bite can range from being painless to severely painful. Most ants do not have pinchers that are large enough to harm humans. Fire ants are the most painful since they release venom under your skin when they sting you.
Over 15 years ago, researchers found that insects, and fruit flies in particular, feel something akin to acute pain called “nociception.” When they encounter extreme heat, cold or physically harmful stimuli, they react, much in the same way humans react to pain.
Ants are good at communicating, and an ant dying lets its fellow colony members know about death. What is this? Ants, however, do not come to the scene of death to attack you or seek revenge. On the contrary, ants come near the dead and as a response to any danger.
Workers serve as undertakers in mature ant colonies, removing dead individuals and carrying them to a trash pile either far away or in a specialized chamber of the nest. In certain species, they will bury the corpse instead.
Some outdoor ultrasonic pest control devices use solar power, too, although these models are better suited for outdoors. After connecting to a power source, the device emits an ultrasonic sound. This sound is not pleasant to ants, so they will gradually begin to move away from that area.
Ants communicate through body language
They can tell the other ants things by lightly touching or stroking the receiver in different ways. This way, they can combine signals of pheromones with that of touch and body language, providing an advanced form of communication.
The short answer is ants have something similar to blood, but scientists call it “haemolymph”. It is yellowish or greenish. In vertebrates (animals with backbones such as humans, cats, dogs, snakes, birds and frogs) blood's main job is to move important things around the body.
Social insects communicate mouth-to-mouth. If you've ever watched ants, you've probably noticed their tendency to "kiss," quickly pressing their mouths together in face-to-face encounters. That's how they feed each other and their larvae.
Resting ants exhibit loss of muscle tone and reduced sensitivity to stimuli. But they don't have a complex enough nervous system to exhibit the different brain wave patterns seen in humans during sleep; nor do they dream.
Ants Do Not Have Lungs
Instead, they have a series of small holes in their exoskeleton that allow them to breathe. When you pour water down an anthill or onto a group of ants, it is unlikely that any will drown because they can access oxygen in more than one way.
