Te Ao Māori
Rock pool shrimps have no specific Māori name. They are small and hidden. Part of the pool’s life. Their transparency is their shield. Invisible but present. Watching. Waiting. Surviving. A ghost in the water. Clear but real.
You miss it. It is transparent. Almost invisible. The Rock Pool Shrimp blends into the water. It hides in plain sight. Only a glint of the eye reveals it. Or a sudden flick of the tail. It swims backwards. Rapidly. Escape is its first instinct. It does not fight. It flees. It is small. Delicate. Vulnerable. But fast. Very fast. Habitat is rock pools. Shallow bays. Seagrass beds. It needs shelter. Algae provides cover. Rocks provide protection. It hides among the fronds. Among the stones. It waits. It watches. It feeds. Diet consists of small invertebrates, algae and detritus. It is an opportunistic feeder. It picks at scraps. It hunts tiny prey. It cleans the pool. It removes waste. It is a janitor. A hunter. A scavenger. All in one. Threats include pollution and habitat loss. Oil spills coat the water. The shrimp cannot breathe. It dies. Coastal development removes rock pools. Fills bays. Destroys seagrass. The shrimp loses its home. It has nowhere to go. It is trapped. In a shrinking world. Range is nationwide. Found on both main islands. It prefers sheltered waters. Calm pools. Protected bays. It avoids rough seas. Waves wash it away. It needs stability. Stillness. Safety. Life span is one to two years. Growth is rapid. Moulting occurs frequently. Each moult is a risk. Soft shell means danger. It hides until hardened. Then it returns to the pool. To the algae. To the shadows.
