How Do Lobsters Communicate? – Shocking Facts In 2021
Humans are not the only species that interact with their kind. Lobsters and other animal species do too. Humans communicate by talking to each other. But lobsters communicate in a unique and surprising way. This post will look at how lobsters interact, including other related information you need to know. First of all, let’s find the answer to this crucial question.
Lobsters have a very interesting way of communicating. I think it was one of the most Googled things in 2021. In the 17th century, lobster was anything but a delicacy.
It was so abundant that the meat was fed to the pigs and the shells were used as fertilizer. Laws were even passed that prohibited people from treating servants or prisoners more than three times a week. Here you can find out how lobsters communicate.
Lobsters have an unusual way of communicating. Instead of making noises or gestures, they splash them. They have two blisters on each side of the head. Just below their eyes, they have small urine-releasing nozzles, which they use to spray the substance on each other.
What Are Lobsters?
Lobsters are a family of large marine crustaceans. Lobsters have long bodies with muscular tails and live in crevices or burrows at the bottom of the sea.
Three of its five pairs of legs have claws, including the first pair, which are usually much larger than the others. Prized as shellfish, lobsters are economically important and are often one of the most profitable commodities in the coastal areas they populate.
Commercially important species include two species of Homarus (which looks more like the stereotypical lobster) from the North Atlantic Ocean and Norway lobster (which looks more like a shrimp or “mini lobster”): the Northern Hemisphere genus Nephrops and the Northern Hemisphere. southern genus Metanephrops.
How Do Lobsters Communicate?
They urinate on each other’s faces as a way of communicating, both during fighting and during mating. Sprained urine contains a chemical message that can communicate a number of things, including simple recognition, aggression, and attraction. The behavior of lobsters is “strange” to think that the female lobster takes off her clothes to mate.
To grow, lobsters need to shed their shells and regrow a newer, larger one. During this vulnerable period, the female lobster decides to mate, intertwining with a male for 10 to 14 days until she is protected with her new shell and she can move on. She can retain her sperm for up to two years before fertilizing her eggs and is not monogamous. A female lobster can carry the sperm of several partners at the same time.
The green substance of the lobster is the digestive tissue that functions like the liver and pancreas of the lobster. Some people consider it a delicacy, but ingesting the green matter is not recommended as it may be contaminated with toxins.
7 Interesting Facts About Lobsters
While it may be quite disgusting to you that lobsters spend so much of their social life urinating on each other, you have to admit that it is quite incredible that they can communicate complex information such as their social status through these urinary chemical signals.
However, that’s far from the only surprising thing about lobsters. Here are some other lobster facts that will blow your mind:
1. Lobsters Have a Dominant Hand
We all know that humans tend to favor one hand or the other, but researchers have recently begun to investigate whether other animals display the hand as well. Apparently, bonobos and chimpanzees show dexterity at the population level, and even mice tend to prefer to use one hand over the other.
Lobsters can also be left-handed, right-handed, or ambidextrous. They use special receptors in their large, fleshy claws to locate food around them and navigate across the ocean floor. They also tend to favor one or the other claw for combat.
2. Lobsters Don’t Get Old
Of course, locusts don’t live forever, otherwise our world would be completely overrun by locusts. However, unlike humans and most other animals, locusts do not show any significant deterioration in their health or strength throughout their lives.
Lobsters can live to more than 100 years, and even after a century of their lives, they still retain the vitality of their youth. They can also regrow their limbs no matter how old they are.
Lobsters generally die when they run out of metabolic energy to molt and become trapped in a shell that wears away. Eventually, their old shells contract bacterial infections, a condition known as shell disease.
3. Lobsters Are Sensitive
While lobsters have an extremely poor sense of sight and smell, they are actually very receptive to physical touch and temperature. This is due to the hundreds of thousands of tiny hairs that protrude from the holes in their shells. These hairs alert lobsters to small changes in their environment, such as changing tides and the salinity of the water.
Lobsters can also detect changes in external temperature as small as one degree. This can cause them to migrate up to 100 miles per year to find the right conditions for breeding. Think about that temperature sensitivity the next time you want to boil a live lobster.
4. Lobsters Are Cannibals
Lobsters have a highly developed social hierarchy, but that social system is quite ruthless. When food is scarce, lobsters have been known to resort to cannibalism, with larger lobsters eating smaller lobsters. They also tend to eat more voraciously after shedding their shell so that they can rebuild enough metabolic energy to generate a new shell.
In this case, the lobsters usually eat their own shell that they have just molted. Since their old shell is packed with calcium, which is an essential mineral they need to build a new shell, eating their old shell greatly speeds up the process of generating a new shell.
5. Female Lobsters Choose When To Get Pregnant
Lobsters can only mate when the female has molted. When this time in her life comes, she will release pheromones into the water, indicating that she is nearing her fertility time.
The males will then fight over the female, and the champion will subsequently lead the mute female to her cave and protect her from predators while she molts. Once she has detached from her exoskeleton, the male will flip her over and deposit her packets of sperm into her sperm receptacles.
However, the female’s eggs will not be fertilized instantly. In fact, she can carry these packets of sperm in her body for up to 15 months, waiting for the right conditions to release her eggs and fertilize them. If the water is too cold, the female will choose to retain her eggs and look for a warm place.
Once the eggs have been fertilized, the female will glue them to the bottom of her tail with a glue-like substance where they will remain until they hatch. Older female lobsters can carry up to 100,000 eggs at a time.
6. You must cook lobster 24 to 48 hours once dead
A live lobster dies the moment it dries up. And once dead, it can stay fresh for 24 to 48 hours. During this period, you should make an effort to cook the dead lobster. Any further delay and your lobster will no longer be fresh.
7. Lobsters have teeth, but they’re not located in the head
Lobsters have teeth, along with their claws to crush things. But his teeth are not in his mouth, as many people would expect.
Lobster teeth are in its stomach. His belly is also a short distance from his mouth. The eaten food is then chewed in the crustacean’s stomach.
How Lobsters Squirt Pee When Communicating?
We have mentioned the unique way that lobsters interact. Now how do they manage to squirt pee?
Examine a lobster, particularly the head region. You will find two bladders on either side of the head. Under each eye, you will find a small urine release nozzle. That’s where they release the substance on each other’s face when they communicate.
What substance does the stream of water from the lobsters come out of the nozzle contain? Lobster urine is a chemical messenger and not just any urine. This chemical allows the animal to communicate various things. These include recognition, attraction, and even aggression.
Do Lobsters Never Produce Any Sound At All?
This is not entirely true. There is a species of European lobster that produces a sound by rubbing its antennae. This screeching sound is even so loud that it can be heard three kilometers underwater.
Scientists are still not sure what the exact purpose of this noise is, but they assume that it is primarily to protect against predators. However, it is true that there are no species of locusts that have vocal cords. Talking or singing crustaceans will remain in the realm of animated films.
Do Lobsters Have Emotions?
Lobsters are really sensitive and delicate animals and lobsters have been shown to feel at least one emotion: anxiety. A study was conducted to prove (or disprove) this in crayfish that are of the same order as lobsters. And we also eat crayfish after boiling them alive.
Anxiety in crayfish has been shown to appear to be caused and controlled by serotonin, which is an important hormone believed to play a role in human anxiety. They treated the anxiety in the crayfish with benzodiazepines; in the same way that we do with humans.
“Sources of stress or danger provoke fear, a basic emotion, and generate immediate responses, such as escape, freezing or aggression. Stress can also lead to anxiety, a more complex state that is considered a secondary emotion because it occurs when the stressor is absent or not clearly identified.
