Often called water fleas, Daphnia are small crustaceans that are one of the most studied living organisms. They can be used to investigate the compound eye, digestive system, reproductive system, appendages used for movement and life cycle stages. They also make great experimental animals, commonly used in physiological studies, including the effects of drugs on heart beat rate and temperature on metabolism. They are an easy-to-grow food source for hydra and small fish. Science Resource Box's living culture usually contains adults with eggs, juveniles, and neonates.

Note: Culture contains approximately 30–40 organisms per container. One culture is sufficient for a class of 30 students.

Species: Probably Daphnia carinata which has recently been synonymised with Daphnia thomsoni.

Great supplies are available at the moment!

NOTE: WE DO NOT DELIVER IF HIGH TEMPERATURES ARE FORECAST AS DAPHNIA ARE SUSCEPTIBLE TO HOT CONDITIONS IN TRANSIT (FROM CANTERBURY). WE WILL NOTIFY YOU WHEN THEY ARE DISPATCHED.

FEEDBACK:

"I thought I would get in touch and let you know that my daughter Nicola won first prize in the science division at the Manawatu Science and technology fair for her project, using the Daphnia you sent. She was able to culture them and look after them thanks to your helpful advice. She performed tests to see if different sunscreens affected them. Nicola was able to get some microscope pictures of the Daphnia (just using a cell phone at 25 x magnification - but they are surprisingly good) and she was also able to measure their heart rates. 
She is still culturing them as a hobby - but I have requested they go outside so I can finally get my bath back!!
