What happens if a crab loses its leg?

Another reason crabs lose a limb is when a crab moults and does not shed their entire exoskeleton in one piece, but instead section by section, over a number of days. Generally if they survive the mount they grow their limbs back again (regeneration) and can be happy and healthy

Explanation:

answer; ///i believe the correct answer is (

answer: - few nutrients

high pressure

low temperatures

explanation: 1. few nutrients:   open-ocean zone is located way far from the land, which is the main source of the essential nutrients.2. high pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.3. ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface. 4. varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.5. low temperatures:   the temperature of open-ocean zone ranges from a low of -2°c to an average of 17°c
