Some species of crabs, such as ghost crabs, golden ghost crabs, and shore crabs, are predominantly nocturnal, meaning they are active at night However, other species of crabs, such as fiddler crabs and Ocypode ghost crabs, exhibit a constant circadian rhythm that mimics the ebb and flow of the tides, turning dark during the day and light at night Carcinus maenas, a species of crab, is primarily diurnal, although activity also depends on the tide, and crabs can be active at any time of day.
Most crabs are not strictly nocturnal, but they are typically more active at night or during low-light conditions when they are less vulnerable to predators and have a better chance of finding food.
However, some species of crabs, such as the ghost crab, are strictly nocturnal and remain hidden during the day.

Crabs can exhibit varying levels of diurnal (active during the day) or nocturnal (active during the night) behavior depending on their species and habitat. While some crab species are primarily nocturnal, others are more active during the day or may be crepuscular (active during dawn and dusk).
Nocturnal crabs often have adaptations that enable them to navigate and find food in low-light conditions. They may have larger eyes, enhanced sensory structures, and heightened sensitivity to light and movement. These adaptations help them forage for food, avoid predators, and engage in other necessary activities during the night.
