Chordata: Protochordata to Amphibia · Zoology

What is the function of the 'lateral line system' found in both fish and aquatic amphibian larvae?

  1. Detection of light intensity and moving shadows
  2. Detection of water currents and pressure waves
  3. Regulation of core body temperature
  4. Production of chemical pheromones for mating signals
Show answer and explanation

Correct answer: Detection of water currents and pressure waves

The lateral line system consists of mechanoreceptors called neuromasts that detect vibrations and pressure changes in the surrounding water. This helps the animal navigate, avoid predators, and locate prey in murky water.
