"Could lobsters hold the key to eternal life?"
Lobsters are a family of crustaceans that live in waters across most of the world's coastlines. There are 30 known species of clawed lobsters and 45 species of spiny (or rock) lobsters.
The largest lobster species is the American lobster, which can be constitute from the coasts of North Carolina into Newfoundland. Because American lobsters grow continuously throughout their lives, they tin reach sizes larger than whatsoever living crustacean. The largest known American lobster weighed in at 44 pounds 6 ounces (20.one kg)!
Lobsters are animals that are closely related to insects considering they accept an exoskeleton and jointed legs like a spider. They're omnivores eating both fish and algae. Lobsters have poor eyesight, so they depend on their ability to gustation and smell while moving across the bottom of the ocean.
5 Incredible Lobster Facts
- With a brain in their pharynx and teeth in their breadbasket, lobsters have some of the about unusual anatomy across the fauna kingdom. Their eyes discover shadows and light, but not colors or images. Their breadbasket contains their "teeth," a gastric mill that crushes up food. A lobster's brain is located in its pharynx and is near the size of a grasshopper's. Their heart and central nervous organization lays in their abdomen. In addition, lobsters "taste" with their feet and "hear" using a series of sensory hairs on their legs!
- A lobster underbelly is as strong as car tires! The underbelly membrane of lobsters (which protects against rocks on the seafloor) is near as stiff as industrial safety!
- The largest lobster ever recorded might take been 100 years old! The largest lobster ever recorded was caught off Nova Scotia in 1977 and weighed 44 pounds half dozen ounces, according to the Guinness Volume of World Records. While age estimates of lobsters are inaccurate, it is believed this lobster may take been 100 years old. Acquire about the longest living animals here.
- Lobster used to be considered "cockroaches of the bounding main." In the early on 1800s lobsters were so plentiful in New England that they occasionally would wash ashore in piles two feet high! While lobsters today are seen as a "gourmet" food, they were so plentiful at the fourth dimension that Massachusetts servants demanded they merely be served a maximum of three dinners per week!
- The key to eternal life? Unlike most animals that terminate growing once their developed phase is reached, lobsters grow continuously throughout their life. Does this hateful lobsters could hold the central to "immortal life?" To read more, coil down to our "could lobsters live forever?" section!
Lobster Scientific Name
While the American lobster is its common name, its scientific proper noun is Homarus Americanus. Other commonly used names for the American lobster include the Atlantic, or Maine, lobster besides as the true lobster. A closer look at the taxonomy of the lobster reveals that it belongs to the Nephropidae family and is in the class Crustacea.
The spiny lobster is a subspecies of the American lobster. However, spiny lobsters live in tropical waters and don't have big claws like American lobsters.
Lobsters are animals that vest to the guild of Decapoda. The Greek give-and-takeDecapodadeka meaning ten andpous meaning feet.
Lobster Appearance and Behavior
When you think of a lobster, you may picture a scarlet lobster sitting on someone's dinner plate. Yet, they don't turn red until after they're cooked. The American or Maine lobster is green dark-brown in colour. Lobsters can be plant in different colors, simply these variations are extremely rare. The Maine Fisherman's Alliance estimates that:
- Every ane in two meg lobsters is blue
- Looking for a yellow lobster? They're seen once every 30 million lobsters
- And white lobsters are fifty-fifty rarer! The risk of seeing a white lobster is about one in 100 one thousand thousand!
The brownish color of near lobsters allows them to blend in with the sand and rocks on the bottom of the ocean. This can keep them hidden from predators. If a lobster spots a predator, it will scoot backward using its tail fin to move into a rock crevice. The fastest speed on record for a lobster moving backward is 11 mph.
A lobster'due south body has two main parts covered in a hard shell. Information technology can grow to exist a little more than three anxiety long. This animal is well-nigh one-half as tall as the fridge in your kitchen. Lobsters vary in weight. They can weigh from one pound to 15 pounds. Of course, there are lobsters that counterbalance more than 15 pounds. The heaviest lobster was defenseless offering Nova Scotia in 1988, it weighed more than than 44 pounds!
The American lobster has two claws, antennae and ii tiny black eyes. Its eyes don't play a big part in its nocturnal hunting activities. The pocket-sized sensory hairs on its ten legs and feet assistance a lobster to place its prey. Too, a lobster uses its antennae to scent prey fifty-fifty if it's far away. Just imagine of a lobster moving through the murky sea h2o using its legs and anxiety to spot its casualty!
Lobsters are alone and shy animals nigh of the time. Withal, they become aggressive when defending their territory against other lobsters. One lobster may push another with its claws in an effort to move it out of the territory.
Lobster Habitat
American lobsters live in the northern Atlantic Ocean. They prefer cold water habitats and live on the floor of the ocean hiding between rocks and digging in the sand. Different lobster subspecies, such as the Spiny lobster, live in warm, tropical waters like the Gulf of Mexico, the Caribbean Sea and off the coast of Florida in the Atlantic Ocean.
The tiny eyes of a lobster have thousands of lenses. Their eyes are sensitive to bright light, then information technology'southward a good affair they live at the bottom of the bounding main! Though they can't run across clearly, lobsters can encounter shadows and dim images which helps them avert predators moving into the area.
These crustaceans use both of their claws to dig into the sand near a rock to brand itself a home. This home tin serve equally protection against predators.
Scientists have found that American lobsters migrate away from the shoreline in the winter and leap. They want to live in the warmer, deep water during the cold atmospheric condition months. Every bit the weather warms up in the summer and stays warm into early fall, they move back toward the shore. Some lobsters motility upward and down the shoreline never staying in ane identify.
Lobster Diet
What do lobsters eat? Lobsters are omnivores. They eat mussels, sand fleas, clams, shrimp and sometimes tiny fish. They are slow-moving then they commonly hunt slow-moving casualty. They grab hold of their prey with their potent claws and squeeze. If they can't find any of these animals to eat, lobsters eat plants that abound underwater.
Lobster Predators and Threats
Lobsters have many predators including eels, venereal, seals and stone gunnels. An eel is able to push its thin torso into rock crevices to catch a lobster that's hiding there. Seals are fast swimmers and tin can catch lobsters with their powerful jaws. In addition, some fish such every bit flounder and cod also eat lobsters. However, the biggest threat to lobsters is human. Large numbers of lobsters are caught in nets to sell in seafood markets and restaurants.
When it comes to disease, lobsters can suffer from beat out affliction as well as different types of fungus and parasites. They are likewise threatened past chemicals and other pollutants in the ocean waters. The official conservation status of lobsters is To the lowest degree Concern.
Lobster Reproduction, Babies and Lifespan
Lobster mating involves a dominant male that typically mates with a grouping of females. A unique aspect of lobster mating is that females must shed their difficult-outer vanquish before mating, which leaves them at risk of predation. During this period females volition live within caves inhabited past males, who offer protection. After approximately two weeks' time, the females shell will have regrown and she can get out with fertilized eggs. At this point, a new female will join the male.
A female person lobster carries sperm from a male so she can fertilize her eggs in July or August. She carries her eggs on the underside of her belly for about ten months. The typical lobster carries 8,000 eggs at a time. Merely some female lobsters tin carry as many as 100,000 eggs! After x months, the female releases the lobster larvae too known every bit hatchlings into the ocean waters. A female person lobster breeds every two years.
For four to six weeks, the larvae floats on or near the surface and eats plankton. During these weeks, the larvae molts (sheds their vanquish) several times growing a new one. Later on shedding its quaternary shell, the larvae is big enough to sink downward to the sea flooring.
Not surprisingly, its estimated but about ten pct of the lobster larvae grow large plenty to sink into the ocean. Ten percent of 8,000 is 800 larvae. These tiny larvae are eaten by fish, seals, sea gulls and other animals before they're large enough to sink. Simply imagine a seal swimming by and eating hundreds or even thousands of these little larvae at once.
In one case a immature lobster does descend to the ocean floor, it makes its home by excavation in the sand below a rock. At this betoken, the young lobster is about ane pound.
Lobsters can live to exist 50 years old or older. As they age, they can endure from shell rot and various types of parasites. The oldest lobster in the world was caught in 2009. Scientists believe it's 140 years old.
Lobsters have the ability to regrow legs, claws and antennae if they fall off due to injury or affliction. In fact, scientists believe that losing a claw or leg is not a painful experience for a lobster. Information technology tin can exist lifesaving and prevent infection to the crustacean. This regrowth makes information technology a little easier to come across how a lobster can live such a long life in the body of water!
Lobster Population
The population of American lobsters in the Gulf of Maine is approximately 250 million. Though millions of lobsters are defenseless each year by fishermen, the population is holding steady. The total population of spiny lobsters and others that live in tropical waters is non known. The official conservation status of American lobsters is Least Business organization. As a note, if a fisherman catches a female lobster who is carrying eggs on her abdomen, it'due south against the law to continue her. The fisherman must put her back in the h2o. This is 1 of the efforts being made to make sure the lobster population steadily grows.

Lobster FAQs (Oft Asked Questions)
Are lobsters bugs?
No, not exactly. Sometimes lobsters are called bugs considering they share a few characteristics with them. For one, both lobsters and bugs like grasshoppers have an exoskeleton (a hard shell).

Are lobsters carnivores, herbivores or omnivores?
Lobsters are omnivores. They chase sea creatures including mussels, clams, shrimp and sand fleas. Simply, if a lobster can't observe any of those animals, it will eat seaweed and other undersea plants. The larger of a lobster's claws is chosen its crusher hook. It is the larger of the two claws. It's used to shell the shells of clams, oysters and like lobster prey.
Are lobsters ambitious?
Normally, lobsters are shy, harmless ocean creatures. Merely, a lobster will become ambitious if its territory is invaded by another lobster.

Do lobsters eat one another?
Some people believe that lobsters eat one some other. This is known as cannibalism. But, this is not a proven fact. Lobsters accept been observed to attack one some other when they are packed together in a minor tank. Simply, in the wild, lobsters aren't known to have this behavior.
Could lobsters live forever?
You may accept seen headlines for lobsters claiming they hold the key to eternal life and could fifty-fifty contain a country called "biological immortality." Then, what'due south the real story behind lobsters and living forever?
The idea that lobsters could conceptually live forever comes from their production of an enzyme named telomerase. In almost vertebrates (similar humans) telomerase is only produced in early stages of life and aids in growth. However, lobsters appear to produce telomerase throughout their lives, which means they go along to grow larger and even regenerate limbs at advanced ages similar 100.
However, even with this fascinating biological quirk, lobsters will dice equally they historic period. The reason is that as lobsters get older the energy required to shed their shell (molt) becomes too great and they cease shedding their exoskeleton. Once lobsters terminate molting, leaner begin infecting their shells, and somewhen leads to lobsters perishing whether by beat rot, or scar tissues that conjoin their bodies to their shells.
The bottom line: while lobsters take an interesting biological quirk that allows them to continue growing throughout their lives, they will perish from one-time age as they're unable to molt whatsoever longer.
