They have a unique brown color that helps them blend in. - **Category:** [Amphibians](https://www.snappit.app/explore/categories/amphibian) - **Rarity:** Common - **Danger:** 2/5 · Low - **Snaps:** 111 - **Habitat:** Forests and wetlands - **Also known as:** Northern Wood Frog ![Wood Frog](https://res.cloudinary.com/drieglelr/image/upload/v1771424482/objects/5651.jpg) ## Appearance The Wood Frog has smooth skin, typically reddish-brown, tan, or gray, with a distinctive dark mask from its snout extending back over its eardrum. Its underside is whitish, and it often has light lines along its jaw. ## Taxonomy - **Kingdom:** Animalia - **Phylum:** Chordata - **Class:** Amphibia - **Order:** Anura - **Family:** Ranidae - **Genus:** Lithobates ## Interesting facts - Male wood frogs sound like a flock of ducks quacking when they call for mates! - Their amazing spring breeding choruses are often one of the very first sounds of spring. - They are 'indicator species'; their health tells us if the forest environment is healthy. - Wood frog tadpoles are mostly vegetarians, munching on tiny algae and decaying plants. ## Special abilities - **Ice Blocker:** Wood Frogs can freeze solid and thaw out later because their bodies produce a natural antifreeze, helping them survive winter. - **Forest Camouflage:** Wood Frogs have mottled brown and tan skin that helps them blend perfectly with leaf litter and tree bark, hiding from predators. - **Quick Leaper:** Wood Frogs have powerful hind legs that help them make quick, long jumps to escape danger or catch fast-moving prey. ## Measurements & details - **Length:** 3.5-7 cm - **Weight:** 0.005-0.02 kg - **Lifespan:** 3-5 years - **Speed:** 8 km/h - **Clutch Size:** 1000-3000 - **Metamorphosis:** 45-70 days ## Diet & Feeding Wood Frogs are tiny hunters, using their sticky tongues to catch small insects and spiders. - **Age differences:** Tadpoles eat algae and detritus; adults are carnivores, eating small invertebrates. - **Primary Foods:** Ants, Beetles, Spiders, Slugs, Worms, Flies - **Foraging Method:** Ambush ## Ecological connections - **Eaten by:** Common Garter Snake (*Thamnophis sirtalis*) — Predates adult and juvenile frogs. - **Eaten by:** [Red-tailed Hawk](https://www.snappit.app/explore/red-tailed-hawk) (*Buteo jamaicensis*) — Hunts frogs from above. - **Eaten by:** [Raccoon](https://www.snappit.app/explore/raccoon) (*Procyon lotor*) — Forages for frogs near water. - **Hunts:** Silky Ant (*Formica subsericea*) — A primary food source for adults. ## Traits - [Camouflaged](https://www.snappit.app/explore/traits/camouflaged): Camouflaged describes organisms that possess coloring or patterns that allow them to blend into their environment. - [Insectivorous](https://www.snappit.app/explore/traits/insectivorous): This trait identifies organisms whose diet primarily consists of insects and other small invertebrates. - [Ancient Lineage](https://www.snappit.app/explore/traits/ancient-lineage): This trait signifies organisms belonging to a very old evolutionary group with ancestors dating back millions of years. - [Forest](https://www.snappit.app/explore/traits/forest): Forest habitats are terrestrial environments dominated by dense tree cover, supporting a high diversity of plant and animal life. - [Hibernating](https://www.snappit.app/explore/traits/hibernating): Hibernating animals enter a state of metabolic depression during cold periods or when food is scarce, characterized by reduced body temperature and activity. - [Wetland](https://www.snappit.app/explore/traits/wetland): This habitat trait identifies species found in wetlands, which are areas of land saturated with water, either permanently or seasonally, including marshes, swamps, and bogs. - [Freshwater](https://www.snappit.app/explore/traits/freshwater): Freshwater habitats include non-saline aquatic environments such as rivers, lakes, ponds, and wetlands, vital for numerous species. - [Regenerative](https://www.snappit.app/explore/traits/regenerative): Regenerative organisms possess the ability to regrow lost or damaged body parts, tissues, or organs. - [Nocturnal](https://www.snappit.app/explore/traits/nocturnal): Nocturnal animals are primarily active during the nighttime hours, typically resting or sleeping during the day. ## Collections - [Amphibians](https://www.snappit.app/explore/collections/amphibians) - [Reptiles & Amphibians](https://www.snappit.app/explore/collections/reptiles-and-amphibians) ## Safety **Danger:** 2/5 · Low Look but don’t touch.
