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 101: Molting. Lobsters donât grow the way people do. Unlike humans, a lobster has a rigid exoskeleton that it must get rid of before it can grow any larger. So before molting, lobsters reduce the size of their extremities by drawing water from them so their old shell isnât too tight. Then, the shell breaks between the tail and the body (called the carapace).
