Amazon's Tiny Guardians: How Zebra Snails Fight Pollution

In the Amazon's coastal areas, where tides rise and fall and seasons change, tiny zebra snails are doing something amazing. They are helping scientists understand pollution levels in these waters. Researchers studied these snails at three different spots along the coast. Each spot had different amounts of human activity. They looked at the snails' bodies and their chemical defenses during both the wet and dry seasons. They also checked them at high and low tides. The snails showed different responses to pollution. In the most polluted area, the snails had stronger defenses during the rainy season. But in the cleaner area, their defenses changed more with the tides. This shows that these little creatures can adapt to different pressures. They might be a great tool for keeping an eye on the health of these delicate ecosystems. But why does this matter? Well, coastal areas are like the kidneys of the planet. They filter out waste and support lots of life. If we understand how these snails cope with pollution, we can better protect these important areas. It's a big job for such a small creature, but the zebra snail is up for the challenge.
