What is unique about the larvae of the Anopheles genus?

The larvae of the Anopheles genus are notable for their lack of air tubes, which distinguishes them from many other genera of mosquito larvae. In contrast to other mosquito larvae that often possess elongated air tubes for respiration and typically position themselves at an angle to the water surface, Anopheles larvae are usually found lying flat in the water. This adaptation allows them to thrive in various aquatic environments while avoiding detection by predators. Their unique morphology plays a significant role in their behavior and survival, showcasing how specific anatomical features can influence the ecological niches that these insects occupy.
