Oceans Animals Affected as Climate Change Progresses

Ocean animals are diverse, with each species having specific adaptations that allow them to thrive in the water.

As the ocean changes, marine life must further adapt or face extinction.

Let's look at specific examples of how does climate change affect the ocean animals.

Temperature Changes

In the last decade, the oceans have continuously warmed up, and marine life has struggled to keep up with the changes. Some marine life, like coral reefs, has been weakened by warming temperatures. The coral turns white and brittle before eventually dying.     Other marine life expands its territory by moving into areas where the water was previously too cold for it.

For example, bluefin tuna and Atlantic mackerel were previously found in a narrow band of the North Sea. Therefore, they have expanded their territory northward.     The ocean is warmer at the top than at the bottom as sunlight warms the top. Therefore, some marine life has moved deeper into the water. This is particularly true of certain species of zooplankton, which are small, drifting organisms.

Many species of fish rely on them as a primary food source. Therefore, as they move downward, they impact food resources, which may affect the number of animals in many species.

In some cases, while they have had to move the top level down, they have not been able to move the bottom layer down. Therefore, there is more competition in a smaller band of water.
