- Card rarity: Uncommon
- Fish

The Modoc sucker is a rare species of freshwater fish native to northern California and southern Oregon. It grows to a length of about 7 in (18 cm) and becomes sexually mature at 4 in (10 cm). It feeds on algae, small invertebrates and detritus, and hides under stones, detritus and overhanging vegetation. It is found in only a few streams and is listed as an endangered species in California and the United States. Conservation measures have been put in place such as fencing the streams in which it lives from livestock. It was previously rated as "endangered" in 1973 by the International Union for Conservation of Nature, but this rating has now been changed to "near threatened", and the U.S. Fish and Wildlife Service removed the Modoc sucker from the federal list of endangered and threatened wildlife in 2016.
