Recent studies show that the survival rate of infant dolphins in the wild is 75%. In zoos and in aquariums, the survival rate is 86%.

Can dolphins self-abort a fetus?

Dolphins have been known to spontaneously abort or reabsorb a fetus in response to environmental stress, health issues, or genetic abnormalities. This process is thought to help ensure the survival of the mother and the group by conserving resources for healthier offspring.


How many does it reproduce?

Generally, an organism reproduces to produce offspring that can inherit its traits and continue its lineage. The number of offspring produced can vary significantly between different species and reproductive strategies. Some organisms produce many offspring with low chances of survival, while others produce fewer offspring with higher chances of survival.


Why do asexually reproducing organism often produce many offspring?

Asexually reproducing organisms often produce many offspring to enhance their chances of survival and colonization in their environment. Since they can rapidly generate large numbers of genetically identical individuals, they can quickly exploit available resources and adapt to favorable conditions. This high reproductive rate also compensates for potential environmental hazards or predation that may affect their survival. By increasing the number of offspring, these organisms maximize their overall reproductive success.


Why would an organism like a fish want to overproduce offspring?

Fish may overproduce offspring to ensure that some survive in hazardous environments or are consumed by predators. By having more offspring, the chance of some surviving to reproduce can increase, leading to a greater likelihood of passing on their genes to the next generation. This strategy can help maintain population levels in fluctuating or unpredictable environments.


Does a bird that has more offspring have greater fitness?

Not necessarily. Fitness is determined by an individual's ability to survive and reproduce successfully in its environment. While producing more offspring can increase the chances of passing on genes, the quality of those offspring and their survival rate also play a significant role in determining fitness.
