What is a Blackfin Pupfish?
The Blackfin pupfish is named for its dark fins. It is a type of pupfish, which are small, hardy fish. They are known for living in tough environments like salty or warm waters.
Where Do They Live?
Most types of pupfish live in their own separate areas. But Lake Chichancanab is a very special place. It is home to seven different kinds of pupfish, including the Blackfin pupfish. This is rare to see so many types living together.
Are They Endangered?
Sadly, many of the pupfish species in Lake Chichancanab are in danger. Only the Blackfin pupfish and the C. labiosus are still found in good numbers. The other five types are almost, or completely, extinct in the wild. This means they no longer live freely in nature. Some of these rare fish are still kept safe by scientists.
What Do Blackfin Pupfish Eat?
The Blackfin pupfish mostly eats detritus. Detritus is tiny bits of dead plants and animals. It also includes other small pieces of organic matter. They find their food by sifting through the sand at the bottom of the lake. This is different from other pupfish that might eat from different places.
How Do They Mate?
When it's time to mate, the female Blackfin pupfish might choose to mate with other pupfish species. This is not common for many fish. Male Blackfin pupfish have special markings and behaviors to attract females. These actions are similar to other pupfish in their lake.
Who Was Enrique Beltrán Castillo?
The scientific name of the Blackfin pupfish, Cyprinodon beltrani, honors a famous person. This person was Enrique Beltrán Castillo (1903–1994). He was a Mexican biologist. The fish was named after him to celebrate his 25 years of working as a biologist.
