What do human eyes have that fish eyes lack?

Human eyes have a fovea, which is a high-density area of cones allowing for detailed central vision. Fish eyes lack a fovea and have a different structure with a higher proportion of rods, which are more sensitive to light but less precise in detail. Additionally, human eyes have a lens that can change shape to focus on objects at different distances, while fish eyes typically have a fixed lens.

Sudden death in fish could be due to a variety of reasons, including stress, water quality issues, parasites, or underlying health conditions. The odd coloring and behavior changes could indicate an underlying health issue. It's important to monitor the remaining fish closely for any changes in behavior or appearance, and consider testing the water parameters to ensure they are optimal for the remaining fish.

Animals that live in the midnight zone?

Animals that live in the midnight zone, also known as the abyssopelagic zone, include deep-sea creatures like gulper eels, anglerfish, vampire squids, and deep-sea dragonfish.

How can clown fish avoid getting stung by anemones?

They don't. They have built up a tolerance to them. Some types can still harm the clowns enough to do damage however .

Actually-

They are the only fish that do not get stung by the tentacles of the sea anemone. Clownfish have a slimy mucus covering that protects them from the sea anemone. However, if this covering is wiped off of a clownfish, it will get stung and possibly be killed when it returns home to the anemone. The clownfish and the sea anemone help each other survive in the ocean. The clownfish, while being provided with food, cleans away fish and algae leftovers from the anemone. In addition, the sea anemones are given better water circulation because the clownfish fan their fins while swimming about.

How do ocean currents effect the fish?

Ocean currents can affect fish in various ways. They can help distribute nutrients and food sources, impacting the availability of prey for fish. Currents can also influence fish migration patterns, as some species use them for navigation or to conserve energy while swimming. Additionally, changes in ocean currents due to factors like climate change can disrupt ecosystems and potentially impact fish populations.

What does the bottom fin on fish do?
