Did you know that lobsters communicate with one another? With the help of their antennules, they can detect chemicals released by other lobsters to determine how long ago they were nearby. This is how lobster communities stay connected and how lobster families reunite after being apart for a while.
What’s their antennules? Lobsters have a pair of antenna-like appendages near the eyes called “antennules.” These are sensory organs and they help lobsters communicate. When one lobster releases chemicals, other nearby lobsters can sense it to find out how long ago that lobster was there.
But how does this tell them which direction the other lobster is in? The chemical releases by crustaceans contain methyl ketones (also known as methoxides) which produce distinctive smells or odors depending on how many carbons atoms are attached to them — from just two up to five. In order for these small molecules to be detected by another animal, they must travel through water so when they break down into smaller components, they rise to the surface.
This is how a lobster can tell how long ago something happened by how fresh it smells or where on the water’s surface the odor appears from.

Expand the article in order to give a more thorough explanation on how they use their antennae and claws for communication. Provide an example of how this is done, as well as how other animals do it differently if that applies.
How lobsters communicate with each other using antennas and claws: A lobster will wave its antennae back and forth while at rest or walking around during the day (or both) which can be seen by others from about 25 centimeters away . When another lobster waves its antennas rapidly back and forth, this indicates aggression – sometimes this means “stay away” but it may also just mean “I am aggressive.
But lobsters do not just use their antennae and claws for aggression or warning – they can also fight with each other: In order to show how strong they are, a lobster will tap another on the carapace – this is how he lets others know that his claw strength (as well as size) is greater than theirs . When one lobster taps another, it usually indicates submission because he knows the fragility of both his own limbs and those of his opponent.
Lobsters also have been shown to threaten predators by waving their antennas over them when threatened from more than 25 centimeters away; this may be done in an attempt to scare off potential threats to themselves.” [“-” how lobsters communicate”]\
What is a lobster?
A lobster is an aquatic animal that lives in the ocean. They are scavengers and feed on dead carcasses, seaweed, shellfish or anything they can get their claws on. Lobsters have two sets of antennae – one set for smelling out food and another to sense how far away something is from them. Lobster males mate with female lobsters by stretching out her long tail so he can insert his abdomen underneath it where sperm will be passed through into her body cavity. Male lobsters also have claw-like structures called nippers which they use to pry open the female’s carapace during mating season (which lasts between March and October). Female lobsters carry eggs around under their tail
Lobsters have a unique way of communicating with each other using their antennae. When they sense danger or are trying to find food, lobsters will rub the antennules at the end of their antennas against one another and this sends out chemicals that create an odor trail for them to follow. These trails can last between two days up until six weeks depending on how fast-moving it is in the water. Lobster communication also includes how far away something is from them by sensing how much light refracts off its body – if you see glitters then it’s close, but if you don’t see anything then either there isn’t anything around or it’s too dark/far away for your eyesight to detect!
