Some see 5.0 seconds a possibility. Because 6' 5 Usian Bolt broke the mathematical model that had fit 100-meter record data for almost a century, his incredible performance has reset the bar for how fast researchers believe humans ultimately can run.
Lobsters may eat other lobsters in captivity, but this has not been observed in the wild. It takes an American lobster 6-7 years to get to an edible size, but that is just the beginning. Lobsters are long-lived animals, and are thought to be capable of living over 100 years.
Lobsters grow by molting their hard exoskeleton, and they do so a lot: the average lobster can molt 44 times before itâs a year old. By the time lobsters reach the age of seven, they molt once a year, and after that, once every two to three years, growing larger with each successive shedding of its exoskeleton. The largest lobster on record, caught in Nova Scotia in 1977, weighed 44 pounds, six ounces and measured 3.5 feet in length.
