The Sea of Cortez holds a world of quiet marvels just beneath its glittering surface. Among them are sea stars, slow-moving and ancient, scattered across reefs like living jewels. They don’t leap or flash or roar. Instead, they offer stillness, pattern, patience, and an entire universe of detail if you take the time to look. Here are 10 fascinating insights into the sea stars that call this warm, vibrant sea home.
Sea stars are not fish. They’re echinoderms, close relatives of sea urchins and sand dollars. Their bodies are arranged in radial symmetry, like a wheel with natural grace built into its design.
From deep purple to sunflower yellow, sea stars in the Sea of Cortez show off a palette that would impress any painter. Some are smooth and soft-looking, others are rugged and armored.
This species is instantly recognizable, sprinkled with dark, raised nodules that resemble chocolate chips. It looks like a bakery treat, but definitely admire only — no sampling.
Lose an arm? Not a problem. Sea stars can regrow what’s missing. In some cases, one arm with a piece of the central disk can regrow an entirely new star.
Underneath, sea stars have hundreds to thousands of tiny tube feet. They move, climb, hold, pry, and sense the world. It’s like watching a star-shaped creature walk on invisible fingertips.
Sea stars are patient hunters. When they find clams or mussels, they use those tube feet to slowly pull the shell open. Then they extend their stomach outside their body to digest. Strange but brilliant.
By feeding on shellfish and algae, sea stars help keep populations balanced. Their quiet work maintains the harmony of reefs, rocky zones, and seagrass beds.
Many sea stars have tough, plate-like skin that acts as natural armor. They handle strong surf, predators, and even shifting temperatures with surprising strength.
You’ll find them in shallow reefs and rocky shorelines. Look close, breathe slow, and watch for tiny movements. Sea stars reveal themselves slowly, like a story unfolding.
Sea stars are delicate, even if they look tough. Touching or moving them can cause stress. Admire with your eyes, and leave them in the world they belong to.
The Sea of Cortez is full of wonders that reward curiosity and patience, and sea stars are perfect reminders of that.
