Can small fish also eat big fish?

The growth rates and individual sizes of marine fishes at each stage are very different, as far as we know: the smallest individual is the micro goby (Pandaka pygmaea), with a length of only 7.5 at 1000m. 11.5mm; The largest can reach 20 meters, like the whale shark (Rhincodon typus). The period of most rapid growth in fish length is generally before sexual maturity; after that, most of the food consumed by the fish is used for the maturation of sexual products and reserves fat for the winter, and only a small part is used for growth in length, so growth slows down; at the senescence stage, growth in length stops almost completely. The growth rates of different species are also different. Some fish can reach the same size as their parents a year after hatching, while others can preturn several years. The lifespan of marine fish varies depending on the species. Some species in the families Gobiidae and Myctophidae live less than a year, while some sturgeons can live up to 100 years. The maximum age of large yellow croakers found along the coasts of Jiangsu and Zhejiang in China is 29 years, and the maximum lifespan of Atlantic herring is 23 years. Some species of fish, such as salmon (Oncorhynchus keta) and European eel (Anguilla anguilla), all die after spawning for the first time at sexual maturity.
