What primary activity defines the Yellow Bullhead as a nocturnal bottom-dweller?

Answer

Feeding and general movement occur after sunset

The Yellow Bullhead's lifestyle is firmly categorized by its adherence to nocturnal patterns, classifying it as a nocturnal bottom-dweller. This means that the crucial activities related to sustenance acquisition and locomotion are principally executed under the cover of darkness, after sunset. Engaging in activity at night provides several evolutionary advantages, notably evading diurnal visual predators such as certain birds or mammals. Furthermore, this timing aligns with the peak activity periods of many of its preferred invertebrate prey items, maximizing foraging efficiency when they emerge from cover.
