Lobsters are invertebrates, which means they don't have a backbone. Their exoskeleton supports their body from the outside, like insects, which they are more closely related to. Both insects and lobsters are in the phylum Arthropoda. Within Arthropoda, lobsters are part of the class Crustacea, which they share with crabs and shrimp.
Lobsters have much longer lifespans than most crustaceans. A study of European lobsters found that the average lobster lifespan was 31 years for males and 54 years for females. The study also found some females that lived over 70 years. Lobsters have indeterminate growth, which means they continually increase in size as they age, with maximum sizes...
Humans are far from the lobster's only predator. Seals like to eat lobster, as do cod, striped bass, and other fish.Eels are capable of slithering inside the rock crevices where lobsters like to hide. Crabs and shrimp eat very young lobster at high rates. All lobsters live in the water full-time and are and benthic (that's the scientific term for b...
When there is a high density of lobsters and not very many predators, lobsters will eat each other. This phenomenon has been observed in the Gulf of Maine, where overfishing (which reduces lobster predators like cod and halibut) has created a perfect environment for lobster cannibalism. Under more typical circumstances, lobsters eat a variety of fo...
Lobster blood (called hemolymph) has molecules called hemocyanin that carry oxygen through the lobster's body. Hemocyanin contains copper, which gives the blood its blue coloring.Some other invertebrates, like snails and spiders, also have blue blood due to hemocyanin. In contrast, humans and other vertebrates' blood contains iron-based hemoglobin ...
Most lobsters are a combination of brown, grey, green, and blue. Lobster coloration generally corresponds to the local environment, which enables lobsters to camouflage themselves from predators. Genetic factors can result in an atypical coloration, like a vivid blue, yellow, or white. These colorations are extremely rare; according to the Maine Lo...
Strangely though it may sound, lobsters can communicate by peeing at one another. They release urine from the nephropores, located at the base of their antennae. These urinary olfactory cues serve a number of different purposes related to hierarchy and mate selection. After male lobsters have established a hierarchy through fighting, they can recog...
Lobsters live in dark and murky environments on the sea floor. They have eyes on either side of their heads, but they mostly rely on their antennae to explore the world around them. Most lobsters have three sets of antennae. The longer, larger ones are used to probe their local environment, and the two smaller sets of antennae detect chemical chang...
Some scientists argue that lobsters lack the brain anatomy to feel pain as humans understand it, and that what we interpret as a lobster's pain experience (like thrashing in a pot of boiling water) is actually a painless reflex. However, there is research to suggest that lobsters may be able to experience pain. A 2015 study found that crabs — which...
Oct 6, 2020 · They are nocturnal and at night they can often be found crawling on the ocean floor seeking out a meal. They can crawl in all directions and back into their burrows. Lobsters eat a wide variety of prey including small fish, small mollusks, other bottom-dwelling invertebrates, and seaweed.
These crustaceans search for food along the seafloor at nighttime, which makes them nocturnal. Reproduction of the Lobster These creatures cannot reproduce until after the female molts, and her shell is soft.
