The red-backed poison frog (Ranitomeya reticulata) is a small, colorful frog that belongs to the Dendrobatidae family. These frogs live in trees and eat insects. They are known as poison dart frogs because some groups of people historically used their powerful toxins on hunting darts. The red-backed poison frog is the second most poisonous frog in its group, after the splash-back poison frog. Its poison can be dangerous to humans and can even kill small animals like chickens. You can find this frog naturally in the Amazon rainforest in countries like Peru and Ecuador.

Why is the Red-Backed Poison Frog Poisonous?
The red-backed poison frog has a moderate amount of poison. This poison is its main way to protect itself from predators. Most animals in its home cannot eat it because of these toxins. To warn others, the frog shows off its bright colors, especially its fiery red-orange back. This is why it's called the red-backed poison frog!
These frogs do not make their own poison. Scientists believe they get the toxins from the tiny insects they eat, like ants, mites, and beetles. The frog's body is immune to these poisons, so it absorbs them and stores them in special glands under its skin. If an animal tries to attack the frog, the poison can seep out through cuts or even through the skin. This defense works very well against mammals and birds. Some snakes in the Amazon, however, have a small resistance to the poison and might sometimes try to eat these frogs.
What Does the Red-Backed Poison Frog Look Like?
The red-backed poison frog is one of the smallest poison dart frogs. Because of their tiny size, they are sometimes called "thumbnail" frogs. Male frogs can grow to about 12 millimeters long, which is less than half an inch! Females are a bit bigger, reaching up to 15 or even 20 millimeters.
Like all poison dart frogs, R. reticulata has very bright colors and patterns. These colors are a clear warning sign that they are poisonous. The red-backed poison frog has black legs with a cool blue mesh pattern, a black belly, and a back that can be bright orange or scarlet red.
Since they live in trees, these frogs have special sticky pads on their toes. These pads help them grip surfaces and climb easily. Because they are so small, they often try to show off their bright colors or climb higher into trees to escape from animals that might want to eat them. If they can't escape, they will use their poison to defend themselves. These frogs are also quite slim, which helps them squeeze into small hiding spots.
Life Cycle and Reproduction
Red-backed poison frogs usually live in small groups of five or six. When the wet season ends, several of these groups come together for a big breeding gathering.
Just like other poison dart frogs, the male frogs try to attract females by calling out to them. They also gently stroke and lick the females. A female frog will show she is interested by stamping her back feet. Then, the two frogs will mate. The timing of their breeding means that the eggs will hatch when the next wet season begins. This ensures the baby tadpoles will have plenty of water to survive.
Once the eggs hatch, the male frog carries the tiny tadpoles on his back up into the tree canopy. The tadpoles have a special sticky slime that helps them hold onto their father. The male R. reticulata will then place the tadpoles into small pools of water that collect inside plants called bromeliads. The female frog will then visit these pools and lay infertile eggs for the tadpoles to eat. When the tadpoles grow into small froglets, their parents lead them to an existing group of red-backed poison frogs. All members of the group accept the young froglets, but only their parents will continue to look after them.
