Deep-sea crustaceans caught hitching rides on giant sea spiders

Some types of marine life appear to have it easy. While exploring thousands of meters below the waves in the Chilean Margin in the southeastern Pacific Ocean, scientists observed tiny shrimp-like crustaceans known as amphipods (Mesopleustes abyssorum) clinging tightly to much larger giant sea spiders (Colossendeis colossea) that were scuttling on the ocean floor.
