"Viewed in this context, organisms like the saber-toothed anchovies can be called 'failed evolutionary experiments'—short-lived groups that did not survive to the modern day with remarkable ecologies that cannot be predicted on the basis of living species. They have been dubbed "failed evolutionary experiments" that appeared in the aftermath of the disappearance of large predatory fish around 66 million years ago. They have been observed to feed on fish one-third their size, necessitating the mechanism of reversed direction ventilation when feeding.
