The poison dart frog is the common name given to the most poisonous animals on Earth.

Native to Central and South America, these species of frogs (family: Dendrobatidae) produce several lethal toxins that are capable of killing a human or other large animal with just 2 micrograms (μg). In other words, one drop of their venom could be powerful enough to kill 8000 people.

The most toxic of poison dart frog species is Phyllobates terribilis. Unlike snakes, dart frogs do not synthesize their poisons, but sequester the chemicals they consume from arthropod prey, such as ants, centipedes and mites. This is why in captivity, they produce far less poison than wild frogs due to their change in diet. What makes these frogs immune to their own poison i ...

Meet the Australian turtle frog, in all its pink, stubby, Muppet-faced glory. Their courting sessions last an impressive FOUR MONTHS before any mating takes place.

How did doctors figure out if women were pregnant back in the day? They used frogs, of course! Before the 1960's, the only reliable pregnancy test involved injecting a woman's urine into an African clawed frog and seeing if the frog spawned.

This peculiar method, known as the 'frog pregnancy test,' may sound bizarre today, but it was a common practice in the early to mid-20th century. The African clawed frog, a species native to sub-Saharan Africa, was preferred for this test because of its unique reproductive system.

If a woman was pregnant, her urine would contain hormones that would induce the frog to lay eggs, confirming the pregnancy. While this method may seem unusual by modern standards, it was an early example of using biological indi ...

The Black Rain Frog (Breviceps fuscus) is native to South Africa and permanently looks grumpy.

For me, the word that comes to mind is blurt or blob Not sure why. Anyway, here's a little background on what this odd looking frog is all about.

Purple frogs are found in India in the Western Ghats. Purple frogs burrow and one was found as far as 8 meters below the surface. It spends most of its life underground, but emerges for a two-week-long mating stint during the monsoon season. Females will lay approximately 3000 eggs at this time.

Their lineage reaches back 130 million years, though their elusive behavior caused scientists to not have a scientific description of them until 2003. They are currently labeled as endangered by the IUCN. ...
