30 Days Wild 2018 – Day Eleven

twt-30-days-wild_countdown_11Day 11: For today’s Close Up Monday, the species in question is the tiny but mighty tadpole.

In our minuscule wildlife pond we have at least two tadpoles. It has been thrilling to see them develop. At present they have grown their limbs and will soon emerge from the pond. Let’s look more closely into their life-cycle.

A female frog or toad can lay up to 50,000 eggs known as frogspawn. Tadpoles are the larval stage of the cycle and hatch from around 1-3 weeks. They eat vegetation and have adapted jaws to do this.

The tadpoles in our yarden have been undergoing a fascinating metamorphosis. Unlike the butterfly, who goes into a crystals to morph, the tadpole changes before our very eyes.

Lungs develop, gills vanish, and limbs grow. I thought one of our tadpoles looked pretty mean! You can see its limbs clearly in the picture. Over time the tail is absorbed and the frog/toad becomes terrestrial.

Lifecyle of Frog/Toad

Frogs and toads areĀ Anuran which means tail-less. Their skin is permeable to water meaning that if a frog is thirsty they just have to jump into water, while toads just need to find a muddy spot in which to absorb moisture through their stomachs. Frogs and toads are carnivorous and eat mosquitoes, files, snails and other invertebrates. Frogs reach maturity at three years old whereas toads at four. Frogs can live up to eight years and toads 12 years. I found most of my information from the Woodland Trust website, here. and Arkansas Frogs and Toads.

Do you have any frogs/toads living in your pond?

Thanks for reading, and keep wild.
