研究发现,马拉维湖的湖蝇 *Chaoborus edulis* 幼虫通过改良其气管系统为增强的浮力调节气囊,能够下潜至超过200米的深度以躲避捕食性鱼类。
原文开头
Evan K. G. McKenzie¹, Maxon J. R. Ngochera², Joseph Chombo², Hayley McLennan³, Roland Proud³,⁴, Tahnee Ames¹, Philip G. D. Matthews¹* The absence of aquatic insects from pelagic marine habitats has been attributed to their air-filled tracheal respiratory system, which could implode at depth while undertaking diel vertical migrations to escape predatory fish. However, we found that the aquatic larvae of the lake fly *Chaoborus edulis* in lake Malawi have modified their tracheal system into reinforced buoyancy-regulating air-filled sacs, allowing them to escape predatory fish by undertaking these migrations well over 200 meters deep into the lake’s anoxic hypolimnion during the day. …
