The Key Differences Between Spiny Lobsters and Maine Lobsters

The key differences between spiny lobster and Maine lobster are appearance, size, habitat, taste, and lifespan.

Spiny lobster (Palinuridae) are a family of crustaceans with about 60 species. Even though they lack pincers, ie, they do not have claws, they have a longer and spiny antenna relative to Maine lobster. Sometimes this antenna can be longer than the body. Spiny lobster seek warmer waters by migrating to deeper water in winter, and they do this by following each other in a single file line.

On the other hand, the Maine lobster (Homarus americanus) is a crustacean with two large, strong, and unequal-sized claws for feeding. One of the claws is very sharp and used for tearing prey into smaller pieces, while the other is used for crushing the shells of mollusks. The smaller front claw is also used for directing food into the mouth. Maine lobster can escape backward from predators by flapping their tails for a quick burst of speed.

Now, let’s look at even more differences between them.

Spiny lobster have small pointing spines covering their bodies for protection against predators, from which their name originated. They vary in color from nearly white to dark red or brown, and they often have dark-colored spots on their tail.

Maine lobster is generally a greenish-brown or black color when alive. Some may possess a blue shell when born. They have strong claws used for feeding. Their shell has green, black, and brown spots.

Spiny Lobster vs. Maine Lobster: Size

Maine lobster are typically between 8 and 24 inches in length and may have a mass of over 20.1 kg (44lbs). As a result of their soft meat and weight, they are considered the heaviest crustaceans globally.

However, spiny lobster can grow up to 60 cm, or two feet, in length with a weight of about 15 pounds.

Spiny Lobster vs. Maine Lobster: Habitat

Spiny lobster are mostly found in the waters of the Atlantic Ocean, the coast of Asia, the Caribbean Sea, and the South of Brazil. They are warm water creatures and migrate to deeper waters in the winter.

Maine lobster, on the other hand, inhabits the Western Atlantic Coast of North America, from Canada to North Carolina. They prefer colder waters, and due to the change in water temperature, their populations are becoming more abandoned in their habitat. However, like spiny lobster, they live in muddy caves, rock reefs, crevices, or burrows on the sea floors worldwide.

Both spiny lobster and Maine lobster are omnivorous and share the same diet. According to Marine Biology, they prey mostly on sea urchins. Their diet consists primarily of small crustaceans, mollusks, fish, snails, decayed plants, shrimp, mussels, and clams on the sea bottom. They use their strong mandibles to crack the shells of their prey.

Spiny Lobster vs. Maine Lobster: Taste

Incredibly, both lobster serve as food for humans. They are widely prized and valued because of their delicious claw meat, but their taste varies due to the respective habitats they live in. You should think about them for your next meal because they both have a sweet and highly flavored briny taste. Usually, Maine lobster are considered tastier than spiny lobster because of their colder habitat.

Spiny Lobster vs. Maine Lobster: Lifespan

According to the Institute of Hematopathology, lobster can survive for many years because of their ability to produce an enzyme known as telomerase in their organs that helps maintain long-term cell proliferation capacity and repair DNA. Spiny lobster can live for 50 years or more, while Maine lobster can live for about 100 years.
