Daphnia, commonly referred to as water fleas, are small crustaceans found in freshwater environments such as ponds and lakes. These organisms exhibit a fascinating ability to adapt when faced with predator threats.
When predators are detected, Daphnia can quickly flee or alter their physical form, notably by developing helmets. This adaptation serves as a defense mechanism against predation.
Key receptors in Daphnia play a significant role in triggering these changes, underscoring the complex interplay between environmental cues and biological responses.
