Breeders often ask whether the Triops sleep at all, as they are active day and night and apparently do not need sleep. With a dog or cat, the owner knows when they are snoozing, but the primeval crabs don’t just lie down in the corner of the aquarium and take a nap. Although sleep is a vital process for most animals, there are some amazing exceptions in the animal world that are able to stay active for days on end without interruption. From fish that keep their eyes open to whales that can sleep half-brain, there are a variety of animals that never need to sleep due to their unique physiological characteristics and adaptations. In this blog post, we will look at some of the most amazing examples of such animals and explore the question of whether Triops can survive without sleep.
Do the Triops never sleep?: Definition of sleep
Let us first look at a precise definition of sleep, even though science has not settled on a clear definition to date. Fortunately, some criteria can be used to describe the state of sleep. Accordingly, sleep is a state in which the ability to react is reduced or delayed, which can be quickly reversed and which brings the organism back into balance. Through these three characteristics, it can be clearly determined whether a species is asleep or not.
However, sleep research is still complex, as neurobiologists and sleep researchers explain. Both land-based animals and birds have fascinating abilities with regard to sleep. There are migratory birds that can stay in the air for up to 300 days, during which time they fall into deep sleep. Although these sleep periods last only about ten seconds, according to sleep researchers, it is still sleep.
And what about the Triops?
The dolphin has to swim to the surface regularly to catch its breath. This raises the legitimate question of when it should sleep at all. But sleep does not necessarily require physical rest. People can also sleepwalk without being motionless. Similarly, dolphins practice what is known as half-sleep. Here, only one hemisphere of the brain sleeps in turn while the other is awake.
Bullfrogs and other vertebrates also sleep, as follow-up studies have shown. Insects such as bees and flies have also been clearly shown to have sleep phases. Since there are no well-founded scientific studies so far, one can only assume that Triops, like other animals, practice some kind of sleep.
