Distribution and Habitat
The generic name of the fish reflects its distribution in the Río Lacantún drainage, flowing through the Montes Azules and Selva Lacandona Biosphere Reserves in México into that country’s largest river, the Río Usumacinta. Its known distribution does not extend beyond a small area in the Lacantún and Lacanjún rivers of central Chiapas. Lacantunia has never been collected in the large Usumacinta River into which these smaller rivers flow. With the description of the new family, there are four catfish families found in this region
These fish inhabit deep river channels and pools with rocks and strong eddy currents. Few specimens were taken in stream mouths.

Famous quotes containing the words distribution and/or habitat:
“In this distribution of functions, the scholar is the delegated intellect. In the right state, he is, Man Thinking. In the degenerate state, when the victim of society, he tends to become a mere thinker, or, still worse, the parrot of other men’s thinking.”
—Ralph Waldo Emerson (1803–1882)
“Neither moral relations nor the moral law can swing in vacuo. Their only habitat can be a mind which feels them; and no world composed of merely physical facts can possibly be a world to which ethical propositions apply.”
—William James (1842–1910)
