Does Egeria or Anigozanthos have more species?
Egeria (plant) Egeria is a genus of three species of aquatic plants in the family Hydrocharitaceae described as a genus in 1849. native to warm-temperate South America.
Coptodon nigrans Coptodon nigrans is a species of fish in the cichlid family. It is endemic to Lake Ejagham in western Cameroon. It was only scientifically described in 2010 and has therefore not been rated by the IUCN, but it likely faces the same risks as the critically endangered "C. deckerti", which is threatened by pollution and sedimentation from human activities, a catfish from the genus "Parauchenoglanis" that has been introduced to the lake, and potentially also by large emissions of carbon dioxide (CO) from the lake's bottom (compare Lake Nyos), although Ejagham is too shallow to contain very high amounts of this gas.
