Common Frog tadpole

My Flora and Fauna Friday post this week is returning to the life cycle of the Common Frog (Rana temporaria).

My last post showed three recently hatched tadpoles on the remains of the frogspawn.

The tadpoles have grown considerably. Their external gills have disappeared and they now resemble a fairly typical tadpole.

Recently Hatched Tadpoles

This week my Flora and Fauna Friday post is continuing my look at the life cycle of the Common Frog (Rana temporaria).

A few weeks ago I posted a photo of some frogspawn in a garden pond.

The frogspawn is now hatching, these tadpoles are on the remains of the frogspawn. They’re recently hatched and are less than a quarter inch (6 mm) long. They will have to grow considerably before they develop into froglets and leave the water.

Young tadpoles have external gills, visible on the side of the head on the tadpole on the left.

Lens-Artists Photo Challenge: Future

This is my contribution to the Lens-Artists Photo Challenge: Future.

The prompt got me thinking about some of the natural history subjects I have photographed over the years. Butterfly eggs that will hatch into caterpillars that in the future will pupate and emerge as a butterfly for example.

After coming up with quite a few different life cycles I remembered my photos of the various stages in the development of a Common Frog (Rana temporaria). Some of them were published in a school textbook to illustrate the life cycle.

Multiple clumps of Common Frog spawn forms a large mass in a garden pond in Cheshire, England.

After a while the eggs in the spawn hatch into tiny tadpoles a few millimetres long. Here, three tadpoles are clustered together on an egg.

Over the following weeks the tadpoles grow enormously, this individual is now around 30 millimetres long. It won’t be long before this tadpole starts to develop legs.

After a while the tadpoles develop legs, their tails shrink and they emerge from the water as tiny froglets.

I skipped a few photos in an attempt to keep the post short.
