Lobsters are cold-blooded - meaning their body is determined by the temperature of the water it lives in. Studies show that lethal temperatures for lobsters range from 75-86 degrees Fahrenheit.
Coastal bottom waters off the Long Island sound reach an average of 71.6F in the summertime months and push a lobster's limit. Because the water in the western sound is shallow and doesn't mix very much with the deep Atlantic Ocean waters, its temperature depends on the air above it. If air temperatures are too high, the bottom waters where lobsters live, can also heat up.
