In the Intertidal Zone

Ever wonder what fascinating creatures there are in the Intertidal zone? Or what kinds of adaptations they use? Almost all plants that are algae live in this incredible zone. Some other names for this amazing zone are the High Tide Zone, Mid Tide Zone, and Low Tide Zone. The Intertidal Zone is also called the shallow ocean zone, and has a lot of tide pools. This zone stretches from the surface to 660 feet, and you can find jellyfish, crabs, fish, and sea turtles. Adaptations are a species ability to change to its surrounding to survive. Even though it is hard living in the harsh, Intertidal Zone, there are three amazing organisms that survive these conditions using cool adaptations, and they are the purple sea urchin, the starfish, and the jellyfish.

Although there are many fascinating animals that can call the Intertidal Zone home, the starfish, or sea star, is one that really stands out. To begin, National Geographic reports, “most sea stars also have the remarkable ability to consume prey outside their bodies. Using tiny, suction-cupped tube feet, they pry open clams or oysters, and their sack-like cardiac stomach emerges from their mouth and oozes inside the shell. Swimming in the ocean, the stomach then envelops the prey to digest it, and finally withdraws back into the body.” Because the starfish needs many ways to eat while in the Intertidal Zone, this is one example of a way that they can find food, because food is hard to find in the ocean. After that, interestingly, starfish, with skeletal and calcified skin, are adorned with striking coloration that can camouflage them and then scare off potential assaulters. Importantly, starfish also need to protect themselves because they don’t want to get eaten. In the ocean, because they are echinoderms, star fish, animals without backbones, bear the firm plates under their skin. Since the starfish needs to go hunting for food, the firm plates help them stay alive and protected.

Although there are many fascinating creatures, the jellyfish is a very cool animal with amazing adaptations. First of all, Enchanted Learning says, “Jellyfish are fish-eating animals that float in the sea - only a few jellyfish live in fresh water. They have soft bodies and long, stinging, poisonous tentacles that they use to catch fish.”

Interestingly, these amazing...
