Integrated gut microbiome and serum metabolomics analysis to reveal seawater adaptation strategy in Chinese sturgeon

Aquaculture Reports
The structure of the fish gut microbiota changes with variations in the living environment, including salinity, which has been regarded as the most important environmental change factor in the transition of Chinese sturgeons, Acipenser sinensis, from ...

Sturgeons, sharks, and rays have multifocal crystalline lenses and similar lens suspension apparatuses.

, 2012
Crystalline lenses with multiple focal lengths in monochromatic light (multifocal lenses) are present in many vertebrate groups. These lenses compensate for chromatic aberration and create well-focused color images.
