    Synodontis multipunctatus. Photo by Mario Rubio García (CC BY 2.0) Synodontis multipunctatus, aka cuckoo catfish, is a parasitic brooder that uses other fish to raise and protect their offspring. S. multipunctatus exploits Lake Tanganyika mouthbrooders by swooping in and laying its own eggs...

    Pundamilia nyererei. Photo by Robert De Leon The vast diversity of cichlid species, especially within the confines for a lake or river, has intrigued scientists. Various hypothesis have been put to the test and while they help explain some of the diversity, there are still many questions that...

    Larval cartilage and bone. Photo by UMass Amherst A new study from the University of Massachusetts at Amherst may answer why evolution alone doesn't account for all variability in cichlids. A study recently published describes how fish exercise, for instance jaw muscles, during the larval stage...

    Teleogramma brichardi. Photo by Dave Hansen A new study looks at the impact the rapid moving waters of the Congo River have on cichlid species. Cichlid species living in fast moving waters tend to have elongated bodies and smaller swim bladders in order to cope with currents. However, a new...

    Diagram from article New research published in Nature Communications claims to explain how so many different species evolved in Lake Victoria in a short period of time. The study titled "Ancient hybridization fuels rapid cichlid fish adaptive radiations" determined that an explosion of species...
  6. Lake Malawi Species
    Lake Malawi. Photo by Paul Venter A new study has been published on the formation of the East African Rift Valley. The findings, sponsored by the National Science Foundation, confirm that the East African Rift Lakes were formed when tectonic plates moved apart. Lake Malawi, pictured above, was...

    Lake Malawi cichlids at Georgia Aquarium. Photo by Fredlyfish4 CC by 3.0 A new study published in the Proceedings of the National Academy of Sciences suggests that environmental change, specifically periods of deep water, created the right conditions for diversification in Lake Malawi...

    Midas cichlid (Amphilophus citrinellus). Photo by George Chernilevsky CC BY-SA 4.0 Sympatric speciation happens when different species evolve from a common ancestor without any geographic barriers to separate them. Each new species still inhabits the same areas and can come in contact with...
  9. Lake Malawi Species
    Pseudotropheus demasoni from Lake Malawi. Photo by Dave Hansen A new study may may shed some light on the incredible diversity of cichlids in Lake Malawi. The question of how over 1000 species evolved in a single lake may have been answered by core samples obtained through the Lake Malawi...

    Lipochromis sp. "Matumbi hunter". Photo by Greg Steeves Normally evolutionary traits help species survive in their environments. Drastic changes in a species' habitat can cause certain traits to become useless. In the case of Lake Victoria cichlids, the introduction of a new predator by humans...
  11. Lake Tanganyika Species
    Electric eel. Photo by Steve Johnson CC BY-SA 3.0 Fish that developed the ability to create their own electricity for defense or to hunt prey is truly amazing in and of itself. What surprised scientist was that the fish that can generate their own electricity evolved this characteristic the...

    Congo River. Photo by Bsm15. Smithsonian.com has put out an interesting article about evolution in the worlds deepest river. The Congo River, with its unique characteristics, has created some interesting evolutionary circumstances. With depths of over 700 feet and an average discharge of...
  13. Lake Tanganyika Species
    Telmatochromis temporalis Magara. Photo by Ad Konings A study of Telmatochromis temporalis by the University of Bristol has shown that competition plays a role in the evolution of new species. T. temporalis is an endemic cichlid from Lake Tanganyika. According to the study, the larger T...

    Male cichlid over its bower An interesting study conducted by researchers at the University of Hull and the University of Nottingham have led to some interesting ideas on cichlid evolution. Specifically, the many different species of cichlids in Lake Malawi that build bowers. Researchers found...

    Scientists have long theorized that cichlids evolved on the ancient continent of Gondwana. Once the continent began to drift apart, it carried cichlids with it to the regions of the world they are found today. Today cichlids are found in South America, Africa, Madagascar, and India. All areas...

    The oldest know cichlid fossils date back 45 million years and were found in Mahenge, Tanzania. The fossils are made up of different cichlids that lived in a small crater lake centrally located between modern day Lakes Victoria, Malawi and Tanganyika. The fossils are complete and well preserved...

    Dr. Melanie Stiassny, Curator-in-Charge of the Department of Ichthyology at the American Museum of Natural History, narrates some of the exploration of the Lower Congo River. The video features Museum scientists on a quest to understand why so many species have evolved in the Lower Congo River.

    Xystichromis sp. "Kyoga flameback" by Dave Hansen Predicting which way plants or animals will evolve as their environment changes is very difficult. However, a Eawag study of African lake cichlids has shown that certain internal and external factors can lead to high rates of specialization and...
