What is Geophagus?

Topics in this blog by and large represent the main interests of the author: zoology, evolutionary biology, fiction & non-fiction. See the most popular posts to the left.

I opted for Geophagus as a title because I’m a keen aquarist, and behind this scientific name lies the fish group of my affection – South American eartheaters. So named on account of their method of feeding: they sift through the substrate in search of victuals. The species below is yet to be scientifically described, even though it’s the most popular eartheater. It was discovered in 1991. This is how it’s called: Geophagus sp. Tapajos Orange Head.

Below is another stunning eartheater sifting the sand, Satanoperca daemon:
