| 41. | This group also contains some species of fungi, algae, and certain microscopic animals, such as rotifers.
|
| 42. | It can be bred in captivity, and the fry can be fed on baby brine shrimp and rotifers.
|
| 43. | Recent genome analysis has shown that they are descended from, and should be considered as, highly modified rotifers.
|
| 44. | However, it can be seen that the black water held greater numbers of rotifers but fewer crustaceans and mites.
|
| 45. | The system also occurs sporadically in some spider mites, Hemiptera, Coleoptera ( bark beetles ), and rotifers.
|
| 46. | Finally, some unusual species " are " confined to one sex, such as the bdelloid rotifers.
|
| 47. | The researchers analyzed chromosome pairs in several bdelloid species, and compared them to pairs from other rotifers that reproduce sexually.
|
| 48. | Bdelloid rotifer genomes contain two or more divergent copies of each gene, suggesting a long-term asexual evolutionary history.
|
| 49. | Juveniles feed on rotifers, in addition to the microcrustaceans and aquatic insect larvae they find when digging into the substrate.
|
| 50. | Bdelloid rotifers are extraordinarily resistant to damage from ionizing radiation due to the same DNA-preserving adaptations used to survive dormancy.
