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.
These hard parts, if a trace of them were left after every molt, would help determine a creatureâs ageâwithout them, approximating lobstersâ birth years is difficult. Previous research has suggested that the biggest European lobster males in the wild live an average of 31 years, and the females an average of 54 years.
