Final answer:
The Atherinidae, or silversides, are not specifically covered in the provided information regarding drought survival. While aquatic animals typically require adaptations to endure drought conditions, the provided content focuses on plant survival strategies and adaptations of other organisms to their environments.
Step-by-step explanation:
The Atherinidae, commonly known as silversides, are not specifically mentioned in the provided information related to drought survival mechanisms in plants and animals. However, as aquatic animals, fish, including Atherinidae, generally do not survive droughts unless they have developed specialized adaptations. Fish adapted to variable environments may survive periods of drought by burying themselves in mud, entering a state of dormancy called estivation, or having the capacity to absorb oxygen in ways other than through gills. The provided information does not detail how Atherinidae deal with drought but refers to how other organisms, like cacti, minimize water loss and mosses remain dormant until water is available.
