Daphnia Pulex, or water fleas, are tiny freshwater crustaceans. They are popular for their flea-like jerky movements while swimming. You can easily find these water fleas in freshwater bodies which is why they are also one of the favourite foods for both adult and young fishes.


Before we delve into the fascinating facts about these tiny creatures, let’s start by understanding where they got their name from. Daphnia comes from the Latin word Daphne, who, according to Greek methodology, was a nymph that transformed in a Laurel tree to save itself from Apollo.


Apart from their role in myths, Daphnia Pulex exhibits interesting biological characteristics that demonstrate various scientific concepts. Do you want to learn more about them? If yes, then Blades Biological Ltd is here to help. They are the top biology science suppliers in the UK. You can buy live daphnia online from their website. Blades Biological is also the only supplier of Carolina Biological‘s preserved organisms in the UK. Science teachers and lab technicians can benefit from their freshwater life set to teach their students in a practical setting.


Let’s learn more about the fascinating world of water fleas, i.e., Daphnia Pulex.

The Physical Description of Daphnia Pulex

Daphnia Pulex, the captivating water flea, boasts a unique physical appearance that catches the eye. These small organisms, measuring around 0.2 to 0.5 centimetres in length, showcase a translucent and elongated body. Their body shape resembles that of a miniature shrimp, with a well-defined head and a thoracic region adorned with a pair of gracefully branching antennae.


Their compound eyes, positioned on the sides of the head, provide them with a remarkable wide-angle field of vision. As they swim through the water, their slender limbs gracefully propel them, creating a mesmerising spectacle. Daphnia Pulex’s delicate and ethereal form serves as a testament to the intricate beauty found within freshwater ecosystems.

The Ecological Significance of Daphnia Pulex

Daphnia Pulex, though small in size, plays a crucial role in freshwater ecosystems. As primary consumers, they feed on microscopic algae and bacteria, regulating their populations and maintaining ecological balance. By studying Daphnia pulex, scientists gain valuable insights into the intricate dynamics of food chains and energy transfer within aquatic ecosystems.


Did you know that they follow a unique reproductive mechanism called parthenogenesis? Through this, females can produce offspring without fertilisation. This topic can be of great fascination for researchers and young scientists studying evolutionary biology and genetics.

Daphnia Pulex in Scientific Research

Buying Daphnia Pulex online for scientific research offers numerous benefits. Blades Biological, a trusted supplier, provides access to high-quality specimens, ensuring reliability and consistency in research findings.


This way, researchers can investigate Daphnia Pulex’s responses to environmental changes, studying their sensitivity to water quality, temperature fluctuations, and exposure to pollutants. These investigations can also contribute to our understanding of environmental health and aid in developing strategies for water conservation and ecosystem management.


Daphnia Pulex also holds immense educational value. As captivating subjects for classroom experiments, these water fleas allow students to explore fundamental scientific concepts in an engaging and hands-on manner.


Through observing Daphnia Pulex, students can grasp ecological interactions, learn about reproductive strategies, and conduct experiments on factors affecting their growth, behaviour, and survival. These experiences cultivate scientific curiosity, critical thinking, and a deeper appreciation for the wonders of the natural world.

Biological Characteristics And Internal Organs Of A Female Daphnia Pulex

The female Daphnia Pulex possesses a fascinating body structure allowing remarkable insights into its internal organs. Encased in a transparent exoskeleton, the body of a female Daphnia pulex reveals intricate details of its internal anatomy. Within this delicate framework, one can observe the beating heart near the head region. Did you know that Daphnia’s heart beats at an amazing rate of a hundred and eighty beats in a minute? Moreover, the digestive system includes the digestive tract and specialised filtering appendages called thoracic limbs.


The transparent nature of the body enables a clear view of the ovaries, where eggs develop, and the brood chamber that houses the developing embryos. Like a living window, the transparent body of the female Daphnia Pulex offers a unique opportunity to study and marvel at the intricacies of its internal organs, fostering a deeper understanding of its biology and reproductive processes.
