How does rat tail survive in polluted water?

Rat tails, commonly known as rat-tailed maggots, thrive in polluted water due to their ability to tolerate low oxygen levels and high organic matter concentrations. They possess a long, siphon-like tail that allows them to breathe atmospheric oxygen while submerged. This adaptation enables them to inhabit environments that are inhospitable to many other organisms, effectively allowing them to survive and even flourish in degraded aquatic ecosystems. Their resilience makes them important indicators of water quality and pollution levels.
