What kind of frog is Carvalho's Surinam toad?

Carvalho's Surinam toad is a fully aquatic frog that inhabits the slow-moving waters of the Amazon River basin. They spend their entire lives in water and do not come onto land. Their flattened body is well-suited for hiding on the bottom, and their small eyes are located on the top of their head. They also lack tongues.

How do Carvalho's Surinam toads breathe?

Like other Surinam toads, Carvalho's Surinam toads primarily breathe through their skin (cutaneous respiration). Their skin is extremely thin, allowing blood vessels to be visible. To enhance oxygen uptake from the water, they have folds of skin along the sides of their bodies to increase their surface area.

What do Carvalho's Surinam toads eat?

Carvalho's Surinam toads are carnivorous, feeding on aquatic insects, crustaceans, and small fish. Since they lack tongues, they capture prey by suction, engulfing it with their wide-open mouths. They have star-shaped sensory organs on their front toes that help them detect vibrations in the water and locate prey.

How do Carvalho's Surinam toads raise their young?

Carvalho's Surinam toads have a unique reproductive method, similar to other Surinam toads, where the female lays her eggs on the male's back, and he protects them until they hatch. The eggs are embedded in the female's back skin, where they develop. When they are ready to hatch, fully formed froglets emerge from the female's back.

Are Carvalho's Surinam toads endangered?

Carvalho's Surinam toads are facing population decline due to habitat loss and pollution, and are listed as Near Threatened (NT) on the IUCN Red List. Their habitat in the Amazon River basin is being destroyed by development and deforestation. Water pollution is also a growing threat. Protecting their habitat is crucial for the conservation of Carvalho's Surinam toads.
