Info:
Water fleas in the broader sense is a colloquial term for a series of small crustaceans from various families and genera (Daphnia, Bosmina, Cyclops, Simocephalus and others) of crustaceans that belong to the zooplankton of fresh water. The name refers to the way the animals move through the water. By intermittently rowing with their antennae, the impression of a flea-like hopping is created.
The species Daphnia pulex is called water flea in the narrower sense and the species Daphnia magna is called giant water flea, the latter, especially the form Daphnia magna straus, is used for water quality tests.
Water fleas usually reproduce asexually, in this case by parthenogenesis. This means that the female adult animals produce eggs whose genetic material is an identical copy of the mother's genetic material, one could also speak of cloning. Male eggs are formed in stressful situations, for example in the event of major temperature changes, food or oxygen shortages, the presence of toxic substances or a high density of predators. The resulting males reproduce sexually with the females, resulting in recombination of the genetic material and thus more diversity, which is advantageous for the survival of the species.
Even with the greatest care, it can happen that feed animals die due to temperature fluctuations or unpredictable events. We accept no liability for this.
