Coelacanth is a rare order of fish. The two extant species include the West Indian Ocean Coelacanth (Latimeria chalumnae) and the Indonesian Coelacanth (Latimeria menadoensis). They follow the oldest known living lineage of Sarcopterygii (lobe-finned fish and tetrapods); this classification means they are more closely related to lungfish, reptiles and mammals than to the common ray-finned fishes. The species are the most endangered order of animals in the world. Both species are threatened with the The West Indian Ocean Coelacanth classified as a critically endangered species. Coelacanths have been found along the coastlines of the Indian Ocean, Indonesia, and Tanzania. (more…)

Also, the location was ideal as many library attendees who otherwise may never take interest in such a subject had an opportunity to attend and engage. (more…)
