[20] The extinct Thylophorops, the largest known opossum at 4–7 kg, was a macropredator. Copyright © 2010 by [35] Opossum spermatozoa exhibit sperm-pairing, forming conjugate pairs in the epididymis. This may ensure that flagella movement can be accurately coordinated for maximal motility. Last 300 years. Like that of all marsupials, the fur consists of awn hair only, and the females have a pouch. Conjugate pairs dissociate into separate spermatozoa before fertilization.
