摘要：
Chaetognaths mainly keep to a preferred depth range by movement and resistance achieved by body shape. Some species, for example Sagitta lyra and S. hexaptera, developed conspicuous, voluminous, gelatinous inner parts in the lateral fins. These are considered an aid toward buoyancy, as they compensate the increasing density caused by maturing gonads. Probably, the small size of the sexual organs of S. enflata can also be regarded as a buoyancy adaptation.
