They can be blue, light yellow, greenish-brown, grey, dusty orange, some calico, and some with spots. However, they all turn red when they hit hot water. The hot water cuts the link between astaxanthin, a red substance contained in the lobster's shell, and protein which in cold water brings out the predominant coloring.
Not yet, but research is underway to develop rearing techniques and to assess the economic feasibility of rearing the American lobster commercially.
Many scientists believe that commercial aquaculture can be achieved in the near future with a sufficient level of effort. Future projections for the culture of the spiny lobster are not, however, optimistic. Unlike the American lobster which has a relatively short larval life several weeks , the spiny lobster has a larval life of about six or seven months. The technical difficulties presented by the fragile, demanding requirements of the early life stages make traditional hatchery methods impractical.
Yes; this is called "reflex amputation. Lobsters have the ability to regenerate some of their body parts; for example, the claws, walking legs, and antennae. The fact that lobsters are capable of limb loss and regeneration shows they have a very primitive nervous system and a different sensitivity to pain compared to humans or other types of animals.
They can "drop" a claw, etc. Could you drop an arm or leg like that? Lobster's teeth are in their stomach. The stomach is located a very short distance from the mouth, and the food is actually chewed in the stomach between three grinding surfaces that look like molar surfaces, called the "gastric mill.
Lobsters "smell" their food by using four small antennae on the front of their heads and tiny sensing hairs that cover their bodies. Their sense of smell is so fine that they can sniff out a single amino acid that tags their favorite food.
The lobster weighed If a lobster gets into a trap first, crabs would not enter the "parlor" or holding section. This is because if a crab starts up the entry to the parlor, the lobster will make aggressive displays which make the crab back down.
Crabs do not keep other crabs out, nor lobsters, so if a crab got in first, lobsters would still come in. In general, crabs are less aggressive than lobsters. Attempts have been made to do so, but with limited success. In the Canadian government discontinued a six-year-old experiment to rear lobsters in the waters off British Columbia.
The decision to drop the project was evidently dictated by economics. Table of Contents How many kinds of lobsters are there in the United States? How big do lobsters get? How far do lobsters travel? What color is a lobster's blood? What are some other names for lobsters? Where are lobsters caught? What do lobsters eat? Is the number of lobsters dwindling? Do lobsters lay eggs? All you need is clean water and a somewhat large container such as a kiddie-pool.
Time commitment is small. The lobsters will grow to full size in a couple months. The requirements for lobster farming aren't that numerous.
Freshwater lobster will tolerate a large variety of water conditions but they do need the temperature to be above 60 degrees. Create a personalised content profile. Measure ad performance.

Caribbean Spiny Lobster Panulirus argus. Crawfish, Rock lobster, Bug, Florida lobster, Langosta espinosa. Quick Facts Region. Population Above target population level in St. Habitat Impacts Lobster trap closures are in place in some areas to prevent damage to ocean bottom habitat. Bycatch Regulations are in place to minimize bycatch. Caribbean spiny lobsters get their name from forward-pointing spines that cover their bodies to help protect them from predators.
They have a reddish brown shell, marked with occasional dark spots and two large, cream-colored spots on the top of the second segment of the tail. Unlike the American lobster, they lack large front claws.
They are harvested for their tail meat. Caribbean spiny lobsters grow by molting — they vacate their old shells while simultaneously absorbing water, expanding their body size. It takes them about 2 years to grow to the 3-inch carapace shell legal-harvesting size.
Spiny lobsters may live 15 years or more, but there is uncertainty regarding this estimate due to the difficulty in ageing this species.
