You can help out cephalopods and other ocean life by reducing pollution to the oceans, much of which comes from sources like those near your home and community.

While not the only cause of ocean acidification, nutrient pollution can severely exacerbate the problem. Even if other cephalopods can somehow compensate for ocean acidification, much of their prey-shell-forming creatures like crabs and other shellfish-may not. These hard parts of their anatomy can be degraded by acidifying oceans, a process known as ocean acidification. Acidic oceans are a problem for cuttlefish which have a unique internal shell called a cuttlebone. Nutrient pollution can also cause the ocean to become more acidic. Along with most animal life in the sea, cephalopods need oxygen too, and these dead zones deprived of oxygen can damage cephalopod development and cause range shifts, which may harm the cephalopods over the long term. These intense growths of algae, called algal blooms, can lead these organisms to take over the water surface. When the algae die and decompose, they use up lots of the oxygen in the water, leading to patches of ocean where oxygen is dangerously scarce, called dead zones. Land pollution can lead to an excess of nutrients in the oceans (called nutrient pollution) which fuel growth of single-celled organisms called algae. This means cephalopods are potentially even more vulnerable to these toxins, which can come from pollution on land. Their prey, such as fish and other shellfish, consume and retain the toxins, which have an amplified impact as the toxins move up the food chain. Because of their role as predators, they are also threatened by the buildup of pollutants, or toxins, in the food chain-a process known as bioaccumulation. These sea creatures are predators-some even use camouflage to blend in to surroundings to help them better stalk, hunt, and capture fish and other small prey. They also may serve as indicators of ocean health, as they can be sensitive to changing ocean conditions. Squids, cuttlefish, octopi-these sea creatures, known as cephalopods, are famous for their association with sea monsters, their supposed intelligence, and as calamari and other seafood.
