Research done on the lifespan of guppieshas found some interesting revelations with regards to aging amongst predators. Most biologists studying aging assume that decreasing external deaths from predation will lead to a longer lifespan. However, surprisingly enough, guppies exposed to predation appear t...
Guppy Lifespan and Life Cycle 4 min read Guppies are a small, pretty species of fish that are extremely popular for home aquariums. While they’re fun in captivity, in the wild they can cause major trouble. Native to South America, guppies are an invasive species on nearly every other...

Sexual Activity and Life Span 来自 Springer 喜欢 0 阅读量: 30 作者: L Partridge 摘要: Most theoretical models of the evolution of life histories have incorporated the fundamental assumption that costly activities such as growth, repair and reproduction are to some extent mutually exclusive (e.g....
However, sexual conflict could also result in selection for increased somatic maintenance to repair the damage induced by toxic ejaculates and hence increase lifespan33,34. For example, Reznick, et al.35 found that higher extrinsic mortality mediated by predation in Poecilia reticulata guppies was ...

For example, the majority of wild freshwater fish average anywhere between 1 to 10 years of life. Fantail guppies, rainbow fish, hatchet fish, corydorascatfish, and tiger barbs can live between 1-3 years. Betas and Jack Dempsey fish can average anywhere between 3-5 years. Meanwhile,angelfish...
Life Span Parrot fish live, on average, 7 to 10 years. As parrot fish age, they change colors and patterns multiple times. Adult parrot fish populations are affected by threats such as habitat decline and fishing.
