Rotifers are found primarily in aquatic environments, and there are thousands of species of rotifers, each with its own preferred habitats. But how do rotifers live out their lives? Click each row in the table below to learn about the major stages of a rotifer's life.
| Embryo Formation | Sexual and asexual reproduction have been documented in the various species of rotifers. Parthenogenesis, a form of asexual reproduction, is by far the most common method of reproduction among rotifers. During parthenogenesis embryos form without fertilization. Rotifers are dioecious, which means that they have both male and female organisms. But, in most species, males have not been observed or are very rare. |
| Embryo Development | When a female rotifer is carrying a developing egg she will either attach the eggs to an external object or carry the eggs, depending on the species. A female rotifer may carry the eggs externally or internally. The length and stages of development of the egg into an adult varies depending on the species of the rotifer and environmental factors. Eggs usually hatch 12 hours after being developed. |
| Rotifer's Adult Life | Rotifers have a short life span. Different variations have been recorded, but they generally span 5 to 45 days. Rotifers and their eggs are prey to other animals such as insects, birds, nematodes, carnivorous plants, fungi, and even other rotifers. |
