Some interesting facts about water fleas:
They reproduce parthenogenetically, that is without mating, and generally, most populations are made up females.
- You can observe a lot with only modest magnificatrion, including: their heartbeat, filter feeding, and giving birth.
- They eat mostly algae, helping to clarify water.
- They are food for a lot of other animals
- Most have a transparent shell, which on the MN DNR website is described as taco shell shaped. Legs are inside of this shell.
- They swim with their two large antenna, using their legs to move water for filter feeding.
- They sport one large compound eye.
- If you've swam in a MN lake, you have probably swam with water fleas (don't worry, remember, they aren't actually fleas).
