What non living animals do seahorses interact with?

Seahorses don't interact with non-living animals, as "animals" by definition are living organisms.

However, seahorses do interact with a variety of non-living elements in their environment, such as:

* Coral reefs: They use coral reefs as shelter and camouflage.

* Seagrass: Seahorses often live amongst seagrass beds, using them for protection and food sources.

* Seaweed: They sometimes use seaweed as a way to blend in with their surroundings.

* Rocks and debris: Seahorses might use these for shelter and camouflage.

* Currents: They are influenced by ocean currents and use them for movement.

* Temperature and salinity: These are crucial environmental factors that affect their survival.

So, while seahorses don't interact with non-living animals, they are deeply connected to the non-living elements of their marine habitat.
