"Amphibians, oh wait it´s a frog."
Amphibians are a unique and diverse group of animals that have captivated scientists and nature enthusiasts alike. Their ability to live both in water and on land, along with their intriguing life cycles, makes them a fascinating subject of study. In this blog post, we'll delve into the life cycle of amphibians, how they lose their gills, how they change so much! And more!
The Life Cycle of Amphibians
Amphibians undergo a remarkable transformation throughout their lives, the fancy word being metamorphosis. This process can be broken down into several stages:
Egg: Usually laid in water. These eggs are often surrounded by a jelly-like substance that provides protection and keeps them moist.
Tadpole eggs, or frogspawns are about 1-3 millimeters in diameter. However, they are often laid in large clusters, which can be quite noticeable in ponds or other bodies of water. These clusters can range from a few centimeters to over a meter in diameter! Quantity over quality.
Larva (Tadpole): Once the eggs hatch, the larvae, commonly known as tadpoles, emerge. Tadpoles are fully aquatic and have gills for breathing underwater. They typically have a tail and lack limbs at this stage. Have you ever held a tadpole in your hands? They are really soft!
Metamorphosis: As tadpoles grow, they undergo significant changes. They develop legs, their tails shorten, and their gills are replaced by lungs, allowing them to breathe air. Frogs can breathe through their skin. The fancy word being: cutaneous respiration. They develop this ability early on. When they were simply a Larva.
Adult: The final stage is the adult form, where amphibians are capable of living both in water and on land. Adults have fully developed limbs and lungs, and they often return to water to reproduce, continuing the cycle.
What Do Amphibians Eat?
Amphibians have varied diets that change as they progress through their life stages:
Tadpoles: Most tadpoles are herbivores, feeding on algae and plant matter in the water.
Adults: Adult amphibians are primarily carnivorous. They eat a wide range of prey, including insects, spiders, small invertebrates, and sometimes even small vertebrates like other amphibians3.
Common Frog (Rana temporaria): Found throughout Sweden, this species is known for its adaptability to various environments.
European Tree Frog (Hyla arborea): Recognizable by its bright green color, this frog prefers warmer regions in southern Sweden.
Great Crested Newt (Triturus cristatus): This newt is notable for its impressive size and the distinctive crest found in males during the breeding season.
Other species include the Common Toad (Bufo bufo), the Natterjack Toad (Epidalea calamita), and the Smooth Newt (Lissotriton vulgaris), among others. All these species are protected in Sweden, highlighting the country's commitment to preserving its natural biodiversity.
Conclusion
Amphibians are truly remarkable creatures, with complex life cycles and diverse dietary habits. The 13 species found in Sweden add to the rich tapestry of the country's wildlife. By understanding and protecting these fascinating animals, we can ensure they continue to thrive for generations to come.

P.S. Begreppa LIED to you. There are now 7000-9000 different species of amphibians. DEFINITELY NOT 4000. What were they thinking!?
