👉 Exechocentrus is a type of fish that can be found in the ocean, often living near coral reefs and on rocky shores. They have a long, slender body with a short tail, a large snout, and a pair of small eyes located at the back of their head. Exechocentrics are known for their ability to filter out pollutants from water, such as ammonia and nitrites, which can be harmful to human health when consumed by humans or animals.
