Coelacanth

Ang mga **Coelacanth** (, pag-aangkop ng Modernong Latin na *Cœlacanthus* "lubog na espina", mula sa Griyegong κοῖλ-ος *koilos* "hollow" + ἄκανθ-α *akantha* "espina", ay tumutukoy sa lubog na likurang mga sinag palikpik ng unang specimen na fossil na inilarawan at pinangalanan ni Louis Agassiz noong 1839)  Ang mga coelacanth ay inakalang naging ekstinto noong Huling Kretaseyoso ngunit muling natuklasan noong 1938 sa baybaying ng Timog Aprika. Ang mga espesye na *Latimeria chalumnae* at  *Latimeria menadoensis* ang tanging mga nabubuhay na espesye ng coelacanth na matatagpuan sa kahabaan ng mga baybayin ng Karagatang Indiyano at Indonesia.  Ang coelacanth ay inakalang nag-ebolb sa tinatayang kasalukuyang anyo nito mga 400 miyong taon ang nakalilipas.
