The name "Marble Trout" comes (obviously) from its scales, which have a marbled pattern to them. Their specific habitat affects the darkness and the exact coloring. Aside from color, the Marble Trout can be identified by their skinny, cylindrical bodies and their 1-2ft size at maturity.
Marble Trout are found only in a handful of rivers and basins in the world. Italy, Slovenia, Croatia, Bosnia and Herzegovina, and Montenegro are the only nations that they are currently found in. They live only in freshwater, and feed on smaller fish and aquatic invertebrates.
Despite their small range, the Marble Trout are considered to be of Least Concern. Though damming and habitat loss have made them rare (and possibly extinct) in some localized areas, there are enough of them, and they breed fast enough, that they aren't in major imminent danger as a species.
