The Man Who Swims With Coelacanths | Wired Science | Wired.com

May 26, 2011

Wired Science has a fascinating interview with Hans Fricke, The Man Who Swims With Coelacanths.

This fish is just amazing. Fricke explains:

They have the slowest metabolic rate known among vertebrates. We made a calculation that a coelacanth needs, for its resting metabolism, 3.8 milliliters of oxygen per kilogram per hour. A tuna needs 400 milliliters. Because coelacanths are always burning at a low metabolic flame, they are able to live in low-energy areas, where there isn’t much food. The lava fields are a low-product habitat. They need about 12 grams of food a day. This is probably the secret of their evolutionary success. They live where hyperactive fish cannot survive.
