Fossil killifish: New findings reveal unforeseen diversity

Killifish, or egg-laying toothcarps, are known for their ecological adaptability and species diversity. Two families of killifish exist in Europe today: the highly species-rich Aphaniidae and the relatively species-poor Valenciidae, which has just three species. How these differences in species diversity originated is one of the questions that the group of Professor Bettina Reichenbacher investigates.
