Ocean sunfishes are fascinating animals and they break several records. The largest bony fish in the world belongs to the species Mola alexandrini and can weigh almost 3 tonnes. Females can spawn up to 300 million eggs at once, which is more than any other fish species! The difference in size between the newly hatched larvae and the mother is probably the largest in the vertebrate kingdom, with the mother being around 60 million times larger than the individual larvae. By the way: the visual acuity of moonfish is better than that of dolphins, so that they can better recognise their preferred prey: jellyfish.
