The Decease Valley pupfish (Cyprinodon salinus), also known every bit Salt Creek pupfish, is a modest species of fish in the family Cyprinodontidae found only in Death Valley National Park, California, U.s.a.. There are two recognized subspecies: C. s. salinus and C. s. milleri. The Expiry Valley pupfish is endemic to 2 pocket-sized, isolated locations and currently classified as endangered.
Description [edit]
The spring-fed pools of upper Salt Creek are the year-circular habitat of pupfish
The Death Valley pupfish is a pocket-sized, silverish colored fish with 6–ix vertical dark bands on its sides. Information technology has an average length of 3.7 cm (1.v in), with a recorded maximum of vii.eight cm (iii.one in).[ii]
The males, often appearing in larger sizes compared to females, turn vivid blue during mating season, April through Oct. The females, along with premature pupfish, tend to have tanned backs with iridescent, silver sides. Both males and females have plump bodies with rounded fins, a squashed head and an upturned mouth.[three] The pupfish tin can withstand harsh atmospheric condition that would impale other fish: water that is 4 times more saline than the ocean, hot h2o up to 116 °F (47 °C), and common cold water downwards to 32 °F (0 °C).[iv]
Distribution and habitat [edit]
This species is known from just two locations in Death Valley: Salt Creek (subspecies salinus) at nearly 49 thou (161 ft) below body of water level, and Cottonball Marsh (subspecies milleri), at about fourscore m (260 ft) below body of water level.[1] They are thought to be the remainders of a big ecosystem of fish species that lived in Lake Manly, which dried up at the cease of the last ice age leaving the present-day Death Valley.[five]
The Common salt Creek subspecies is also found at River Springs and Soda Lake, in Death Valley National Park.[four]
Conservation [edit]
The Death Valley pupfish has been classified as endangered by the IUCN because of its extremely restricted distribution (if the 2 extant locations were treated as a unmarried unit, it would be considered critically endangered). Numbers of individuals at the locations are highly seasonally variable, and fluctuate with water level and flow book. While the entire range of the species is located in a protected area, it may be under threat from accidental introduction of not-native species, local catastrophic events, and excessive pumping of the aquifer that feeds the habitat.[1]
