Rivulus elegans Steindachner, 1880 |
The Cynodonichthys elegans is a special type of small fish known as a killifish. It belongs to the family called Rivulidae. This fish lives in Colombia, a country in South America. You can find it in temporary pools of water in the Cauca River basin and the San Juan River area, especially in the Chocó Department.

What is a Killifish?
Killifish are a group of small, colorful fish found all over the world. They often live in places where water might dry up. Many killifish species are known for their ability to survive in these changing environments. They are not related to "killer" fish, despite their name! The name "killifish" comes from an old Dutch word, "killi," which means "small stream" or "puddle."
Where Does Cynodonichthys elegans Live?
This particular killifish lives in Colombia. It prefers small, temporary pools of water. These pools can form during rainy seasons and then dry up when the weather gets hot and dry. The fish has special ways to survive these tough conditions.
Temporary Pools: A Unique Home
Imagine a puddle that appears after a big rain. That's like a temporary pool! These pools are not always there. They fill up with water and then slowly disappear. Animals that live in these places must be able to handle these changes. For Cynodonichthys elegans, these temporary pools are its natural home.
Life in the Water
Cynodonichthys elegans is a freshwater fish. This means it lives in rivers, streams, and pools, not in the ocean. It's a small fish, like many other killifish. Its exact size and colors can vary, but generally, killifish are known for being quite pretty.
Diet of the Killifish
Like most small fish, Cynodonichthys elegans likely eats tiny insects, larvae, and other small living things it finds in the water. These creatures are part of the rich ecosystem of the temporary pools and rivers where the fish lives.
How They Survive Dry Spells
Some killifish species have amazing ways to survive when their homes dry up. For example, some lay eggs that can stay dormant in the mud for a long time. When the rain returns and the pools fill up again, the eggs hatch. Scientists are still learning about the specific survival strategies of Cynodonichthys elegans.
Conservation Status
The Cynodonichthys elegans is listed as "Data Deficient" by the International Union for Conservation of Nature (IUCN). This means that scientists don't have enough information to know if the fish is endangered or not. More research is needed to understand its population size and if it needs special protection.
Why is "Data Deficient" Important?
When a species is "Data Deficient," it's like saying "we don't know enough yet." It doesn't mean the species is safe, but it also doesn't mean it's in danger. It's a call for more studies and observations. Understanding the fish's habitat and how many there are is the first step to protecting it if needed.
Protecting Habitats
The rivers and temporary pools where Cynodonichthys elegans lives are important. Protecting these natural areas helps not only this fish but also many other plants and animals. Keeping water clean and habitats undisturbed is key for all wildlife.
Discovery and Naming
This species was first described by a scientist named Franz Steindachner in 1880. When a scientist "describes" a species, it means they officially give it a name and write down its characteristics. This helps other scientists identify and study the fish.
The Scientific Name
The scientific name Cynodonichthys elegans has two parts. The first part, Cynodonichthys, is the genus name, which groups together similar species. The second part, elegans, is the species name. "Elegans" often means "elegant" or "graceful," suggesting something about the fish's appearance.
