Coelacanths are large fish, and their size can vary between the two known species.
1. The West Indian Ocean coelacanth (Latimeria chalumnae) typically reaches lengths of about 1.5 to 2 meters (5 to 6.5 feet).
2. The Indonesian coelacanth (Latimeria menadoensis) is generally smaller, with reported lengths of around 1 to 1.5 meters (3 to 5 feet).
These sizes make coelacanths relatively large in the context of fish, and they have a distinctive appearance due to their size and unique physical characteristics.
