Sometimes the smallest things can make the biggest difference.
Especially when it comes to poison dart frogs - who for their size, make an astonishing amount of noise at night time in the jungle.
From the Dendrobatidae family, they come in a variety of different threatening colours morphs and are abundant during the day and the night.
When threatened they secrete a lipophilic alkaloid toxin. The golden dart frog (not pictured) is supposedly carrying enough poison to kill 10 to 20 humans, or 10,000 mice.
