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.

The Study

Researchers studied these snails at three different spots along the coast, each with varying levels of human activity. They examined the snails' bodies and their chemical defenses during both the wet and dry seasons, as well as at high and low tides.

Key Findings

• In the most polluted area, the snails had stronger defenses during the rainy season.
• In the cleaner area, their defenses changed more with the tides.

This shows that these little creatures can adapt to different pressures, making them a great tool for monitoring the health of these delicate ecosystems.

Why It Matters

Coastal areas are like the kidneys of the planet—they filter out waste and support abundant life. Understanding how zebra snails cope with pollution helps us better protect these vital regions.

It's a big job for such a small creature, but the zebra snail is up for the challenge.
