How Do Lobsters Communicate? +5 Incredible Facts About Lobsters

How do lobsters communicate? With their thick shell, sharp claws, and antennae, crustaceans like lobsters stand out from the other species we often see in our environment.

Lobsters are intriguing creatures that communicate with one another through chemicals indicating their sexual status, place in the social order, or if it associates with or prevents mating pairs.

Due to the fact that it is economically significant, it serves as a valuable model in the research of intraspecific chemical interaction.

As with humans, lobsters have a social status-sensitive neural system. These social emigration strategies have allowed them to persist for millions of years.

The amount of serotonin produced increases with social hierarchy.

The supply of serotonin is reduced in proportion to how much defeat it receives. A portion of the chemical gives a sensation of contentment and well-being.

Lobsters uphold a rigid social hierarchy. Only the socially dominant males can mate.

Lobster conflicts establish the social order. The battles are violent, and claws, eyes, and other body parts are frequently lost after being severed by their ferocious pinchers.

Most people often ask the question, “How do lobsters communicate?”

Are lobsters social?

Clawed lobsters are often solitary animals. The only time a lobster may act otherwise is during the breeding season. Thus, much of what we know about their interaction relates to locating a mate and fending off potential romantic competitors.

Some female lobster species dwell in close regions, like the Atlantic lobster, to hatch eggs.

However, instead of sharing valuable space, the lobsters compete for it. On the other hand, spiny lobsters, commonly referred to as crayfish, are very social creatures.

Their communal living provides shelter from predators and facilitates migration because they can alternately follow each other’s slipstreams.

Spiny lobster juveniles grown in solitude take longer to develop than those raised in a group, indicating that social interactions are crucial to their survival.

Thus, while some lobsters are social, others are not. But communication is necessary between the two types.

How do lobsters communicate?

Life would not be possible without communication. Different animal species use different methods of communication.

So how do lobsters communicate? Lobsters communicate by peeing on themselves.

The bladder is right beneath the brain. Lobsters have two bladders that are situated on either side of their heads.

Lobsters also have two easily accessible urine nozzles that expel their urine beneath their eyes.

It sends a range of lobster messages to other lobsters using these nozzles to spew urine at them. When it spills, other lobsters’ “sensing” routes absorb the chemicals in its pee.

Through absorption, lobsters can convert information regarding the other lobster’s status in the social structure from the urine.

The sexuality of the lobster is also indicated in the urine that shoots from their faces.

Why Urine?

Pheromone is substances that act as hormones at the outer surface of the body and can be scented by other lobsters. It is produced by rosette glands,”

Because pheromones are infused into the urine, it facilitates communication between lobsters. A variety of messages are sent when lobsters shoot their urine.

Additionally, the pee has an excellent capability. It can project up to seven lobster lengths! The majority of communication-peeing is related to mating.

The male lobster will shoot urine in the path of the females. Mating occurs if one of them gets attracted to the other’s scent.

Can lobsters communicate using sounds?

Some lobster species use sounds to interact. Spiny lobsters, for instance, have been heard emitting rasping and shrieking sounds.


These sounds appear to be able to do the following based on their frequency and intensity:

  • Letting other lobsters know when a new food source has been found
  • Serve as a warning about potential predators
  • Letting other marine creatures know it is nearby
  • Scare potential predators

It is also known that male European-clawed lobsters can make undersea sounds by wiggling their carapace.

Although scientists are uncertain of its exact function, we know that lobsters will make sounds to be heard amid background shipping commotion.

Lobster mating patterns and their love language

Male and female lobsters use urination as a form of communication, although their intentions are different.

In contrast to how a guy will assert his dominance and draw a mate, a female will utilize her urine to soothe a potential partner. Let’s examine how the pee messaging functions:

• First, it’s crucial to remember that only the fittest male lobsters will be selected for mating.

Female lobsters pick the most vital partners to give their young the most excellent chance of surviving.

• To determine which males are the strongest, lobsters establish hierarchies, such as locking claws, shoving one another, and lashing rivals with their antennae.

Although these confrontations rarely end in death, they can cause damage to the limb. Additionally, the outcome of the fight will be reflected in the pheromones of the participants, which will change.

• Similar conflicts occur less frequently as the mating season goes on. Instead of fighting, males spew urine in each other’s faces, and the pheromone signals indicate the strongest lobster.

• Finally, based on how many successes are represented in each male’s pheromone profile, the females will also be capable of determining which of the guys are the most attractive.

• The males are still quite agitated and tend to snap at other lobsters who approach too closely.

Female lobsters ready to mate will likely spill their pee on the male’s face to shield themselves from being assaulted. This indicates that she is a female and is open to mating with him.

Lobsters never age

Naturally, lobsters don’t live forever; if not, the globe would be wholly populated with them.

Unlike humans and most other animals, lobsters do not significantly lose their health or strength as it ages.

Lobsters have an average lifespan of over 100 years and can still be as active as in their youth. No matter their age, it can regenerate their limbs.

Lobsters often perish when it lacks the metabolic energy to molt and get confined in a shell that has lost its elasticity.

Their aged shells eventually develop shell disease due to bacterial infections.

Some incredible facts about Lobsters

1. A lobster has two stomachs. Surprisingly, one of their stomachs is in their skull, with teeth! It accomplishes the task of mashing the food it consumes.

Just beneath the first stomach lies the second one, which extends to a belly. It facilitates proper digestion.

2. A single lobster claw has a pressure capacity of 100 pounds per square inch. The claw of a 21-pound lobster has enough force to break a man’s arm.

3. In an accident, lobsters can lose a limb, but they can grow it back during the shedding process. Lobsters can shed and regenerate their shells up to 30 times during their typical lifespan.

4. Lobsters are anthropophagus. If there is a food shortage, lobsters will consume one another.

There seems to be a rise in the incidence of lobster cannibalism. We view climate change as the cause of that by many biologists.

5. Lobsters use their legs as a tongue. Lobsters use their chemosensory legs and hairy feet to detect food. It employs its tiny antennae in front of its eyes to locate food farther away.

When a lobster is in a tank, you can observe that it is actively searching for food by tossing dissolved objects in the water.

6. Golf balls were once made from lobster shells. The remaining lobster shells are typically dumped in landfills after processing.

A University of Maine researcher developed golf balls with a solid piece out of lobster shells to make them valuable and accumulate wealth in the lobster industry.

The golf shells are intended for use on fairways next to lakes, oceans, and cruise ships. Furthermore, the shells are reusable.

7. A giant lobster measured between 3 and 4 feet in length and weighed 20.14 kg. It was thought to be at least a century old!

FAQs [How do lobsters communicate]

How do lobsters breathe?

Lobsters use gills that are tucked under the carapace, near the head, to breathe. Although lobsters can survive for weeks if kept cool and damp, their gills function best in seawater.
It’ll swiftly run out of oxygen and perish in a lesser body of water with little water. However, lobstermen claim to have survived longer, even winter dormancy in sheds.

Can lobsters hear?

The idea of lobsters having ears is probably strange to you. However, it makes total sense that if lobsters can produce sound, they can also hear.
Lobsters can hear, but not with ears. Tiny organs are hair fans distributed throughout their body and are used to sense vibrations caused by other lobsters’ shrieking, rasping, or vibrating.

Do Live Lobsters Scream When Boiling?

No, because it is unable to create noises in the same manner that mammals do because it lacks vocal cords.
Boiling a lobster produces a high-pitched sound that is not a scream. Therefore, a lobster that has already been killed when boiled will make the same sound. The noise you hear results from air being forced out of tiny openings in the lobster’s body because it is getting too hot. Most of the air is expelled by the mouth and comes from the stomach.


How do lobsters communicate? Our article has covered several crucial details you should be aware of, as well as how lobsters communicate.

While some lobster species spend most of the year on their own, others establish long-term social groups.

Lobsters communicate most fascinatingly by squirting pheromone-filled pee from beneath their eyes.

With minimal to severe fighting, these chemical signals are used to establish social dominance and win the best mate.
