How is the larva of the Giant Water Scavenger Beetle described in terms of physical appearance?

Having long, segmented bodies resembling centipedes

The larval morphology of the Giant Water Scavenger Beetle presents a significant departure from the smooth, streamlined oval shape typical of its adult counterpart. These larvae are characterized by having elongated bodies that are distinctly segmented. The text notes that their physical resemblance is closer to that of centipedes rather than their adult forms. Furthermore, a key distinction noted about this specific larva is the absence of the posterior siphon, a breathing tube structure found on the larvae of some other diving beetles. Their respiration likely relies on surface contact or general body surfaces, distinguishing them morphologically and physiologically from siphon-equipped larvae.
