Coelacanths and Lungfishes: Sarcopterygii

Coelocanths, Lungfishes, And People

Coelacanths are valued mainly for research. Lungfishes are common in aquariums.


The December 1938 find of a living coelacanth caused disbelief and created one of the greatest biological sensations of the twentieth century. Finding a living coelacanth, so similar to the fossil (FAH-suhl) specimens left in rocks more than seventy-five million years ago, was as inconceivable as meeting a living dinosaur. The living coelacanths are often celebrated as the most unusual case and important example of animal evolution.
