Is ? The Mary fish is neither viviparous nor oviparous, but ovoviviparous. Because Mary fish is fertilized in vivo, the eggs become fertilized eggs in vivo, and the fertilized eggs will be produced after they mature in vivo. This is somewhat similar to viviparous, but ovoviviparous fertilized eggs are always in the reproductive tract of the mother, mainly relying on the lecithin placenta, the mother mainly plays a protective and hatching role for the embryo, and viviparous fertilized eggs will be implanted into the uterus. Ovoviviparous is a reproductive mode formed by the long-term adaptation of Mary fish to adverse environments. Other fish also have ovoviviparous, but most fish are oviparous.
can Mary fish give birth to at a time? Mary fish can give birth to 40-100 small fish at a time. The specific number of small fish depends on the size and constitution of Mary fish. Because the Mary fish is ovoviviparous, the number of offspring has a great relationship with the size. If the size is smaller, the number of offspring will be less. If the size is larger, the number of offspring will be more. There are also Mary fish with better physique that may produce 200 at a time. But the average Mary fish has less than 100 larvae.
