June Sucker
Chasmistes liorus
The June sucker (Chasmistes liorus) is an endangered species of fish endemic to Utah Lake and the Provo River in the U.S. state of Utah. It is named after the month in which it spawns. It is a gray or brownish fish with a paler belly, growing up to about 24 in (61 cm). It lives alongside the Utah sucker, which has a much wider range. Due to the populations of both fish becoming greatly reduced in the lake as a result of fishing, other species such as the common carp have been introduced into the lake. As a result, the June sucker has become "critically endangered" as the pure species is lost as a result of hybridization with the Utah sucker, and predatory fish feed on its larvae. Conservation measures have been put in place and fish are being raised in a fish hatchery for reintroduction.

Description
It is a member of the sucker family Catostomidae, and occurs in sympatry with the demersal Utah sucker Catostomus ardens. Unlike most other suckers, the June sucker is not a bottom-feeder. Its mouth is more rostrally oriented, allowing it to collect zooplankton from the midwater. The fish is dark gray or brownish dorsally, with a white or slightly greenish belly. It has a lifespan over 40 years. Typical specimens range from 17 to 24 in (43 to 61 cm) and reach a weight of 5 lb (2.3 kg).
Range & habitat
The June sucker is known only from Utah Lake in the United States, its feeder streams, and the adjacent Provo River.
