The 3 Types of FROGS Found in Finland! (w/Pics)
Do you want to learn about the different frogs in Finland?
If so, you’ve come to the right place! In the article below, I have listed the frogs you can expect to see. For each species, you’ll find out how to identify that frog correctly, along with pictures, interesting facts, and RANGE MAPS!
Here are the 3 types of frogs that live in Finland:
#1. Common Frog
- Rana temporaria
- Adults grow up to 11 cm long.
- They have a short, blunt snout and partially webbed feet.
- Their coloring varies, from nearly black to pale brown, sometimes red or yellowish. The most typical markings are a white upper lip and a dark patch behind the eye.
The Common Frog is the most widespread frog in Finland.
It lives in nearly every habitat with stagnant water, including ponds, ditches, flooded meadows, and swamps. So if you have a pond in your garden, this species is most likely using it.
Common Frogs breed explosively, meaning that hundreds of these frogs gather together and breed simultaneously. As a result, it’s not uncommon to see the bottom of entire ponds covered in frog eggs during the breeding season.
Their unusual breeding strategy means young frogs emerge in unbelievable numbers during late summer. However, some late-hatching tadpoles hibernate over winter and emerge the following spring instead.
#2. Moor Frog
- Rana arvalis
- Adults typically grow up to 6 cm long, occasionally up to 8 cm.
- Their normal coloring is pale brown with dark brown streaks. They have three ridges that run down their backs.
- During breeding, males turn completely blue. This coloring only lasts a few days.
If you happen to see a male Moor Frog during its breeding season, you won’t mistake it for any other species. These fascinating creatures turn bright blue to advertise when they’re ready to mate! It’s incredible to see a usually plain frog take on such vivid colors.
Although they’re less colorful outside the breeding season, Moor Frogs in Finland are relatively easy to find. They spend most of their time on land and are active during the day. Plus, they’re not as skittish as other species, so it’s easy to get a good look.
Moor Frogs inhabit moors, as their name suggests, but can also be found in flooded meadows, lakes, and temporary water sources.
#3. Edible Frog
- Pelophylax kl. esculentus
- Adults grow up to 10 cm long.
- This large species has protruding eyes, long toes, and a long, pointed snout.
- Its coloring is green on the body and legs, with dark splotches roughly arranged in stripes. Its belly is pale.
The Edible Frog has the most fascinating origin of any frog in Finland.
Although the process is much more complex, in short, this species is the result of a hybrid between two frog species that then uses cloning to reproduce!
I know this seems like science fiction! The fertile female offspring of a Pool Frog and a Marsh Frog can reproduce without using any of the breeding male’s genetic material. So, in essence, she produces clones of herself with the same DNA. Click here to read more about this interesting process called Gynogenesis.
As you may have guessed by its name, this frog is the one used to make the French delicacy of frog legs. Personally, I prefer to observe them in the wild rather than in a kitchen. 🙂
