Introduction to Lobster Biology
Before we dive into the specifics of how long live lobsters can last out of water, it’s essential to understand some basic aspects of their biology. Lobsters are marine animals that belong to the family Nephropidae. They are found in oceans around the world, typically in shallow, coastal waters. Lobsters are ectothermic, meaning that their body temperature is regulated by the surrounding environment. They have a hard exoskeleton, which provides protection and support, and they are equipped with powerful claws and a long, segmented tail.
Lobster Respiration and Oxygenation
Lobsters, like all crustaceans, have a unique respiratory system. They breathe using gills, which are located in the branchial chamber. The gills extract oxygen from the water, which is then transported to the lobster’s body tissues. When a lobster is removed from the water, it can no longer breathe using its gills, and its oxygen supply is severely limited. This is why live lobsters can survive for only a short period out of water.
