Which planet spins the fastest? Jupiter is the fastest spinning planet in our Solar System rotating on average once in just under 10 hours. That is very fast especially considering how large Jupiter is. This means that Jupiter has the shortest days of all the planets in the Solar System.
In general, lobsters are 25â50 cm (10â20 in) long, and move by slowly walking on the sea floor. However, when they flee, they swim backward quickly by curling and uncurling their abdomens. A speed of 5 m/s (11 mph) has been recorded. This is known as the caridoid escape reaction.
Lobster fishermen throw back lobsters that are too small and lobsters that are too big. The small ones need to grow, while the large ones add vigor to the gene pool. In Maine, a lobster's body must be at least 3 1/4 inches to keep, and can't be over 5 inches. When lobsters mate, the eggs aren't fertilized right away. The female carries the male's sperm and chooses when to fertilize her eggs.
