poison dart frog

The poison dart frog is a small frog that lives in Central and South America.

To protect them from predators, one of their main adaptations is their brightly colored skin, which can vary in color from yellow to bright blue or red. This skin warns predators looking to add them to their diet that these tiny frogs are highly poisonous if ingested.

5 Unbelievable Poison Dart Frog Facts!

• A group of poison dart frogs is known as an "army".
• One of this frog's adaptability is its brightly colored body, which ranges from blue to red, black to golden yellow.
• Poison dart frogs are sometimes called "poison dart frogs."
• The golden poison dart frog is the most poisonous of all frogs, with enough toxin in its body to kill more than 20,000 mice.
• Certain varieties of these frog poisons are showing promise in the medical field, including one that has been synthetically engineered for use as a painkiller in humans.

scientific name

These frogs belong to a wide range of genera and species and have many different scientific names. There are over 175 known species. However, they all belong to the Dendrobium family. The scientific name is derived from the Greek word for tree dendro , which is also used for the word dendrology, the study of trees. Batēs is a Greek word meaning "one who steps on". Thus, the surname Dendrobatidae means "one who reads in a tree", or simply "tree climber".

appearance

One of the famous adaptations of these frogs is their brightly colored skin. This skin warns predators of their highly toxic secretions. The term for organisms that have bright colors to warn predators that they are poisonous is called "warning coloration."

Different species come in a rainbow of colors including blue, yellow, red, green, gold and black. One of the most venomous members of the species, the strawberry poison dart frog has a bright red body and blue legs. The golden poison dart frog is also particularly dangerous, with enough venom to kill more than 20,000 rats. It is also the largest poison dart frog species.

However, the truth is that not all members of the poison dart frog family are poisonous, or brightly colored. Some obscure species come in tans and browns, and these species are generally nontoxic to most animals.

These frogs tend to be small, with an average length of about 1 inch. Like most frogs, they have smooth, moist skin and webbed toes.

evolution

It is believed that poison dart frogs first began expressing their signature mutation and evolved from their non-toxic relatives sometime between 20-40 million years ago. In addition to producing powerful venom and striking warning colors, these amphibians must develop resistance to their own toxins in order to survive, an evolutionary hurdle that all venomous creatures must overcome. The poison dart frog does this by genetically manipulating a single amino acid in its DNA.

The wide variety of species and genera all display their own unique color variants, suggesting a high level of genetic diversity in these amphibians, with scientists thinking some new species first appeared as early as 6,000 years ago.

Behavior

Some facts about the behavior of these frogs include their preference to live in the trees closest to the ground, or in leaf litter on the jungle floor. They prefer to rest on leaves and branches.

These frogs rattle and squeak like other frog species, using these calls to build habitat and attract mates. They are mostly diurnal, which means they are active during the day.

These frogs rarely try to hide from predators because their skin is already warning enough. If their toxins don't kill predators, they at least make them highly unappetizing. Predators will remember the frog's unpleasant taste and may not try to eat another frog.

Habitat

These frogs are native to the humid rainforests of Central and South America. They are sometimes confused with another small, brightly colored frog called Mantella, but Mantellas are only native to Madagascar.

These frogs were also introduced to Hawaii. They used to be imported in large numbers into the United States for the pet trade, but this has since slowed down. In Europe, certain species of frogs are smuggled into the country.

Due to their environmental sensitivity, these frogs do not do well in heavily polluted areas.

diet

These frogs use their long, sticky tongues to catch insects. This diet makes the frog a carnivore. Their diet includes termites, flies, ants, and many other types of insects that are plentiful in the habitats in which poison dart frogs live.

Tadpoles can be omnivorous and will sometimes eat algae. They also sometimes get unfertilized eggs from their parents. Some species of frogs are even cannibals, eating other species of tadpoles.

The poison dart frog's diet is thought to be responsible for its toxicity. Scientists aren't sure which insects the frogs eat that make them poisonous. However, captive frogs and fed crickets and fruit flies did not release the toxin from their skin.

Predators and Threats

Because the toxins in their skin make most animals inedible or even poisonous, poison dart frogs do not have a wide range of natural enemies. One species of snake, Leimadophis epinephelus, is immune to poison dart frog venom.

Frogs, including poison dart frogs, sometimes fall prey to chytrid fungi. The disease is an infectious fungus that causes lethargy, weight loss and eventually death. It is highly contagious and threatens more than 100 different frog species.

Many poison dart frog species are listed as endangered or critically endangered due to habitat loss and pollution. Vast tracts of rainforest are routinely burned to make room for farmland and also felled for timber. Some species are also captured and exported for the pet trade.

Reproduction, Babies and Longevity

Poison dart frogs reproduce several times throughout the year, usually in conjunction with periods of rainfall. Both males and females are aggressive during this time – males compete for ideal habitat to call a mate, and females compete for nesting areas. Females have sometimes been known to devour the eggs of other frogs.

Once the male has signaled for courtship and finds a female with whom to breed, the mating process occurs. The male lures the female to a place where he wants to mate through an elaborate courtship ritual. This courtship involves wrestling, petting, and leading the female around. The ceremony goes on for several hours, and the female can lay her eggs, before the pair decide to settle.

Females lay their eggs in moist leaf litter. The number of eggs varies from 1 egg to 40 eggs, with an average clutch of about 10 eggs. Once the female lays eggs, the male fertilizes the eggs. Both parents will guard the eggs, taking care to make sure they don't dry out.

Once the tadpoles hatch, the parents carry the tadpoles about 10 to 18 days after the eggs are fertilized. When the frog parents sit in the tadpole colony, they can climb on the parent's back. Parents take their children one at a time to the small pool where they can grow and mature. The tadpoles develop into adult frogs after a few months. In this young form, they are especially vulnerable to predators.

The lifespan of poison dart frogs has not been well studied. In the wild, some scientists say they live as little as three years. Some species in captivity have been reported to live up to 25 years.

population

The poison dart frog, like many other species in the South American rainforests, is in decline. Some species are endangered or critically endangered due to habitat loss, climate change and fungal diseases. Due to the large number of species and their remote location, accurate population data cannot be measured.

poison dart frog in zoo

These frogs are common sights in zoos and aquariums everywhere. The San Diego Zoo and the Smithsonian have captive poison dart frogs, as well as the Reed Park Zoo and the Seneca Park Zoo.

In zoos, these frogs were fed insects that did not cause the toxins in their skin. They are fed such insects because they often need to be handled by zookeepers and veterinarians while in captivity.
