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.
The American lobster, Homarus americanus, is a species of lobster found on the Atlantic coast of North America, chiefly from Labrador to New Jersey. It is also known as Canadian lobster, true lobster, northern lobster, Canadian Reds, or Maine lobster. It can reach a body length of 64 cm (25 in), and a mass of over 20 kilograms (44 lb), making it not only the heaviest crustacean in the world, but also the heaviest of all living arthropod species.
