21 Interesting Points On Lobsters For Kids

1. What Are Lobsters?

Lobsters are one of the most popular crustaceans who belong to the family of Nephropidae. They are invertebrate arthropods, who possess hard protective exoskeletoniXThe animal's exterior skeleton that supports and shields its body and no backbone. They have ten legs making them famous as ‘decapods’. Typically, lobster means American lobsters. There are about 49 species of these invertebrates present in various oceans throughout the world. Out of the 49 species of these crustaceans, 33 species are in commercial applications. Fishermen catch around 200,000 tons of lobsters every year. In spite of this, lobsters are not yet on the list of endangered species.

2. Is A Lobster A Fish?

No, lobster isn’t a fish. Kids often get confused with this. However, the fact is that lobsters do not belong to the fish species. Fishes are aquatic vertebrates while lobsters are invertebrates that lack backbone. Unlike fishes, a lobster’s body comprises many pairs of legs, and is made up of various sections enclosed in a hard outer shell.

Before the 1800s, Lobsters were cheap and plentiful, which led them to be considered as the poor man’s food. Lobsters did not become a delicacy until after the civil war in America.

3. Where Do Lobsters Live?

American Lobsters are found on the Atlantic Ocean’s coast of North America, Labrador, Canada, and Cape Hatteras and in all other oceans too (1).

  • Lobster lives in fresh and brackish wateriXWater that is not as salty as salt water but saltier than fresh water . So you can find them in any waterbody.
  • These crustaceans like to live in the mud and murk at the bottom of the sea.
  • Lobsters live singly making their homes in the crevicesiXA small crack or aperture, particularly one in a rock or wall and the burrows present on the seafloor and under the rocks where they can hide from predators.
  • Young lobsters make the holes in pebbles, sand, and clay as they find it difficult to locate a gravelly environment.
  • You can also find them beyond the edge of the continental shelf (2).

4. What Is The Anatomy Of A Lobster?

Like most arthropods, a lobster’s body is bilaterally symmetrical. The body of a lobster comprises two main sections:

  • Cephalothorax (Head): The cephalothorax of a lobster contains the cephalon (i.e. head) and thorax (i.e. mid-body section), considered to be the body. A hard shell called carapace covers the body. As many as 14 segments, called somites, fuse together to make the cephalothorax. Also, cephalothorax of a lobster comprises its claws. One of the claws having the sharpest and largest pincers is called the pincer claw, and the other is the crusher claw. Crusher claw is the most powerful claw of the crustacean as it crushes the shell of the lobster’s prey with it.
  • Abdomen: Abdomen is another major part of a lobster’s body. It comprises six sections which do not fuse to enable excellent flexibility and movement of the crustacean. First, five segments of the abdomen bear swimmerets, and they are beneath the tail. The sixth part comprises the tail fan. Lobster can contract and retract its tail quickly and forcefully and move backward.

5. What Do Lobsters Eat?

Lobsters are omnivorous, capable of eating anything that their claws get on, no matter if it’s alive or dead. But they prefer to eat fresh food. Here, we list some of the common foods of lobster:

  • Lobsters prefer crab, starfish, mussels, sea urchins, mollusks, clams, and marine worms prominently.
  • They catch and eat fast-swimming aquatic creatures, such as shrimps, sand fleas, and small fishes.
  • Although lobsters prefer to eat animals, the scarcity of marine animals in their environment in the spring can make them thrive on aquatic plants and sponges to obtain energy.
  • Lobsters do not eat their species; if you heard they are cannibals, then it’s a myth.
  • A lobster may consume a part of its old shell to get enough calcium to make its new exoskeleton healthy.

6. Can Lobsters See?

Lobsters are nocturnal creatures

Lobsters possess poor eyesight. In fact, deep-sea lobsters are often blind. Some species of the crustacean tend to have compound eyes. However, they can view a clear image. With a strong smelling sensation they can detect movements even at night. Lobsters are nocturnal creatures, so they are more active at night.

7. Are Lobsters Left-Handed Or Right-Handed?

Just like humans, lobsters are both left-handed and right-handed. Depending on the position of the crusher claw at the left or right side of the lobster’s body, you determine whether it’s left-handed or right-handed.

protip_icon Did you know?
Lobsters were sometimes referred to as bugs because they shared a nervous system similar to grasshoppers and ants.

8. Do Lobsters Taste Food With Their Legs?

Yes, the feet and legs of the lobsters are chemosensory. Chemoreceptors are present on the small antennae in front of the eyes of the crustacean that helps it in tracking down the food by detecting distant chemical signals and odors that flow with the seawater.

9. Do Lobsters Have Three Stomachs And Teeth In Their Stomachs?

The digestive system of a typical American lobster comprises three stomachs:

  • Foregut: Foregut, the first stomach, includes a gastric mill with a set of teeth for grinding the eaten food into fine particles which pass into its midgut. Having teeth in the stomach is an interesting fact about lobster.
  • Midgut: Midgut, the second stomach, promotes the digestion of fine food particles with the help of tomalley glands, the green colored area.
  • Hindgut: Large food particles which midgut cannot absorb go into the hindgut, and then excreted through the enlarged rectum anus.

10. What Are The Types Of Lobsters?

There are two main groups of lobsters, namely clawed and spiny lobsters.

  • Clawed Lobsters: This class of crustaceans possesses claws, and they usually prefer staying in cold water environments.
  • Spiny Lobsters: Spiny lobsters are also popular as rock lobsters. This group of invertebrates has long antennae in place of claws and spines over their entire bodies, and they thrive in warm tropical and subtropical waters and rocky reefs.

11. What Is The Color Of Lobsters?

Live lobsters are not red in color. They turn red only when you cook them as the heat breaks the protein bonds, releasing astaxanthiniXRed antioxidant pigment that is part of substances known as carotenoids and found in algae, yeast, and certain fishes from its shell. Usually, lobsters are olive green or greenish brown in color. You can also find orange, dark green, reddish, or black speckles on the body of this crustacean, blue color at its joints.

protip_icon Quick fact
Blue lobsters are quite rare. The source of their distinctive blue color is a genetic mutation that leads to the overproduction of a protein called crustacyanin (4).

12. Do Lobsters Grow Forever Till They Die?

Lobsters continue eating their food, reproducing, and growing physically throughout their lifespan. Like other crustaceans, lobsters don’t have a fixed size limit as they continue to increase till they die. They grow by molting their exoskeleton. An average lobster molts 44 times before it turns one-year-old. Up to seven years, lobsters molt once in a year. After it turns seven, a lobster molts once in two or three years growing larger in size after shedding its exoskeleton.

13. What Is The Largest Size Of Lobster?

Records reveal that the fishermen caught the largest lobster, popular as ‘Big George’ in 1974 in Cape Cod, which was about 2.1 feet in length and 37.4 pounds in weight. Later, the fishermen caught the biggest lobster of 3.5 feet long in Nova Scotia in 1977, and its weight was 44 pounds and six ounces. In 2013, fishermen caught a lobster of 27 pounds in Maine which was approximately the size of a toddler.

14. How Does A Lobster Reproduce?

Reproduction in lobsters involves the laying of eggs, which the female carries until they are ready to hatch. After mating, fertilization of the eggs occurs immediately. Like fishes, eggs of a lobster are also popular as roe. Depending on the warmth of the water, a female lobster carries the eggs for about a year in its swimmerets. However, quite a little percent of eggs i.e. only 0.1 percent of eggs reach maturity. Out of 10,000 eggs, just ten eggs will survive for greater than six weeks. The black line present of the tail of the crustacean contains unfertilized eggs that you can eat.

15. Do Lobsters Scream In Pain When You Cook Them?

No, lobsters do not scream; it’s a myth. Lobsters have no throat and no vocal cords to emit noise. The sound that you hear while cooking them is the trapped air in the stomach which gets out with force through their mouth while you cook them. You may listen to the noise for a minute or two after you put the crustacean in a pot of boiling water.

16. Can A Lobster’s Claw Exert Tremendous Pressure?

Crusher claw, one of the claws of a lobster, can exert a pressure of about hundred pounds per square inch. The claw can clamp down a pressure measuring device. This powerful claw possesses molars as it can easily break up hard creatures, such as crabs, mussels, and clams. Lobsters can cause severe pain to others without feeling any pain. The ripper claw tears off the soft fishes and worms.

17. Can A Lobster Regenerate Its Limbs?

Yes, a lobster can regenerate its limbs, and the process is known as reflex amputation or autotomy. Lobsters discard their legs as a survival phenomenon and regenerate them. They can regenerate claws, legs, and antennae as they have a primitive nervous system and differential sensitivity to pain. However, it takes a long time, i.e. about five years, for a pound of lobster to regenerate its lost claw.

18. Can You Make Golf Balls Out Of A Lobster’s Shells?

Usually, the leftover shells of a lobster are put into the landfills. However, golf balls can be made out of them. The core of the balls comprises the lobster shells, which are biodegradable. You can use them for golfing on courses near the water bodies and onboard cruise ships.

19. Why Are Lobsters Popular As Go-To Prison Food?

In the colonial times, prisoners and poor servants used to eat lobsters as they were inexpensive and available in plenty. Also, people used to find them tasteless. However, today, people make various recipes by cooking lobsters, and it’s no longer a poor man’s food.

20. How Nutritious Are Lobsters?

Lobsters carry a high nutritional value. Their meat is a rich source of proteins, for a cup of meat provides you about 28 grams of proteins. Also, lobsters have omega-3 fatty acids that boost cardiovascular health when included in the diet. Just three and a half ounces of lobster meat without butter offers you 96 calories and two grams of fats that prevent you from putting on weight and help you stay in shape.

21. How Long Do Lobsters Survive?

Lobsters can survive up to 100 years
