What is the relationship between water clarity and otter survival?

Otters are extremely important organisms, also known as "keystone" species. They keep aquatic ecosystems healthy because they control other populations such as sea urchin populations that consume kelp, sometimes in excess.

For this reason, otters prefer inhabiting near the kelp, which generally grows in clear waters near shores. They also prey on crabs, marine snails, squid, etc. as they possess the ability to dive as deep as 250 feet.

Therefore, their survival is correlated to water clarity because kelp, the main food of otters' prey (sea urchins), needs clear water to thrive.

Water clarity and otter survival are positively strongly correlated because a clearer water will promote availability of food for otter.

Recall:

Water clarity refers to the amount of light penetration that passes through the water column in an aquatic habitat.

The clearer the water, the more light penetrates into water to reach aquatic plants.

Aquatic plants provides oxygen, source of food, and shelter for other aquatic life such as the otter.

Otter's rate of survival is linked to the water clarity if their habitat, in the sense that, a clearer water means more food for otter.

Therefore, water clarity and otter survival are positively strongly correlated because a clearer water will promote availability of food for otter.
