No, this is not a little tadpole with a red flower garland. This is the Eurycea sosorum, popularly known as the Barton Springs salamander. These salamanders are lungless, and unfortunately, their population is currently endangered. These animals are native to the state of Texas in the United States of America. This salamander was first spotted at Barton Springs of the Zilker Park located in Austin, Texas, and hence this species gets its name. Apart from these springs, they are also found in the Hays and Travis counties. They are easily recognized by the salt-pepper pattern of their skin.
They stay underwater throughout their lives and have tiny feather-like organs, their gills, which help them breathe underwater. Though a little is known about them, you can enjoy knowing about what is already researched about this interesting endangered species.

The Barton Springs salamander is a type of salamander.
This creature comes under the class of Amphibians.
There are thousands of these creatures on Earth, but there is no exact count on the Barton Springs salamander's population.
The Barton Spring salamanders are predominantly aquatic, spotted mainly in springs. They adapt well to freshwater habitats.
These amphibians are native to the spring waters of Barton Springs of Zilker Park, Barton Creek in Central Texas. All four springs, the Parthenia Spring, Eliza Spring, Upper Barton Spring as well as the Old Mill Spring form Barton Springs, and this species is found in all four. These shy little creatures are usually spotted hidden under rocks or dug into the gravel almost 15 ft (4.6 m) under the water surface. They are found peeking through the aquatic vegetation and algae. They prefer clear waters and would shift their locations if the water quality and temperature seem to vary.
The lifestyle activity of this species is not known, but in general, salamanders like to live alone, away from others of their species.
The lifespan of Barton Spring salamanders in their natural habitat is unknown, however, they have lived up to 12 years in captivity.
As it is difficult finding these animals in their natural habitat, information related to their reproduction cycles is based on their lifestyle in captivity. These creatures are found not to be sexually dimorphic. However, you can identify the females by seeing the eggs through their translucent skin. These salamanders can produce throughout the year. The clutch size of these salamanders has a range of up to 40 eggs, having an average clutch size of 22 eggs. The laid eggs are extremely small, each having diameters of 0.06-0.08 in (1.5-2 mm). The larvae hatch from their eggs in two to six weeks. Females are said to lay eggs about six times a year. Once they hatch, the juvenile salamanders have a body length of about 0.5 in (1.3 cm). They reach maturity, the end of their development, within a period of six months after they hatch.
The conservation status of this species stated by the IUCN is Vulnerable.
This species is really small in size. It has a small head, shoveled snout, long slender body as well as elongated feet. However, they have short tails. Their bodies are slightly transparent, and hence the interior of the Barton Springs Salamander, such as the stomach and the eggs clutches in females, are sometimes visible through their skins. They also have five toes on each foot, and four fingers on each hand. This species also has 16 presacral vertebrae in its anatomy.
Their bodies sport the ‘salt and pepper effect, which is due to the coloration of their dorsal parts. This coloration varies from multiple hues of gray to brown, mustard, or even beige. Multiple blotches and speckles of darker brown or olive tone are spread across the body. These speckles appear on the body due to the mixed effects of pigmentation by melanophores as well as iridophores. The presence of these elements also gives a lustrous appearance to the little animal. The eyes of these little salamanders have golden irises. The absence of the melanophores gives a paler look to the Barton Springs salamander.
The limbs and toes are spotted unevenly when observed dorsally, however, ventrally, they are not freckled. The ventral side of the salamander’s tail has a small, yellow-orange strip that runs to the tip of its tail.
But what catches your eye first when you see these little animals are their bright external gills. These salamanders have three pairs of vibrant red gills that sway in motion as they swim in shallow waters.
We love how cute these little ones are, swimming in the water with their bright gills!
Sadly, we are not aware of their means of communication.
The average length of the bodies of Barton Springs salamanders is about 1-3 in (2.54-7.62 cm).
Their bodies are slightly longer than an average wooden toothpick.
Unfortunately, there is no exact information pertaining to the speed of the Barton Springs salamander. We do know that they use the slow water flow to aid their movement under the surface of the water.
Sadly, we do not have information on this. However, considering their small size and similar salamander species, we believe they weigh less than 0.075 oz (2 g).
There are no exclusive names for the female and male individuals of this salamander family.
In general, baby salamanders are called efts.
The Barton Springs salamander diet is usually carnivorous, however, it is sometimes omnivorous too.
This species munches down on leeches, snails, black worms, and even small crustaceans. They also eat brine shrimp, white worms, earthworms, and sometimes aquatic plants too.
No, these little animals are not poisonous, nor are they venomous.
We do not think taking them away from their natural environments and keeping them as pets would be a good idea.
The trend of filtering the Barton Springs pool always included the addition of bleach to clean the water from harmful organisms. However, the presence of these salamanders prevented this tradition. Hence, Austin, Texas applied and received a 15-year permit for the incidental taking of this species during the cleaning process of these pools.
In habitats heaving lesser DO (Dissolved Oxygen) concentrations, studies have shown that this salamander species has an increase in their body movements.
Back in the 18th century, Zilker Park, where the Barton Springs salamanders are located, was dominated by horses.
The popular American star, Robert Redford, apparently learnt to swim in the Barton Spring pools.
Climate change has caused a huge decline in the population of almost every species. The Barton Springs salamander has unfortunately become a victim of this effect as well. Some factors which have caused changes include the increase in UV radiations, unwanted pathogen outbreaks as well as variations in the precipitation pattern. Other causes of this species being endangered include pollution, habitat destruction, and changes in the pH of the water, thus affecting the quality of water. Such environmental changes have also affected the Dissolved Oxygen (DO) concentration of these water bodies.
Risks of the sewer lines breaking open and even chemical or oil spills might lead to a decline in the Barton Spring salamanders’ population. Increased wastage of water has also led to a decrease in the availability of groundwater.
Earlier maintenance practices of Barton Spring included the use of harsh chemicals and high-pressure hoses, which were contributing factors in the declining population of Barton Spring salamanders.
The Barton Springs water is a major contributor to the water supply of the Austin municipality. Thus, its cleanliness and safety have become a major concern. The addition of any contaminants can prove harmful to people depending on this water supply.
Salamanders in general are highly sensitive to the presence of any contaminants in the water bodies. Thus, the Barton Spring salamanders are a key indicator of the safety and purity of the water which comes from these springs and is distributed to Austin, Texas.
The importance of these amphibians in evaluating the water quality has ensured many measures to be taken for their safety.
Evolution in these animals has helped researchers and scientists in looking at the possibility of modern medicine being developed.
