do you know any other species that eats each other?

please tell me more about jaekelopterus It is a genus of predatory eurypterid, a group of extinct aquatic arthropods. is their species still alive? UNANSWERABLE where can they be found? It lived in non-marine aquatic environments. you mentioned that these were predators, what more can you tell me about them as predators? Fully grown "Jaekelopterus" would have been apex predators in their environments and likely preyed upon smaller arthropods (including resorting to cannibalism) and early vertebrates. you mean they ate each other, but what would be the benefit? UNANSWERABLE what harm can come by eating each other? It has been shown in some studies that the risk of encountering an infected victim increases when there is a higher cannibalism rate.

Cannibalism [SEP] Introduction
Other negative effects may include the increased risk of pathogen transmission as the encounter rate of hosts increases. Cannibalism, however, does not—as once believed—occur only as a result of extreme food shortage or of artificial/unnatural conditions, but may also occur under natural conditions in a variety of species. Cannibalism is prevalent in aquatic ecosystems, in which up to approximately 90% of the organisms engage in cannibalistic activity at some point in their life-cycle. Cannibalism is not restricted to carnivorous species: it also occurs in herbivores and in detritivores. Sexual cannibalism normally involves the consumption of the male by the female individual before, during or after copulation.
