Mink Frog (Lithobates septentrionalis)

Family: Ranidae (Typical Frog Family)

IUCN Conservation Status: Least Concern

The Mink Frog can be distinguished from the Green Frog and American Bullfrog (two closely related species with which it shares part of its range) thanks to its smaller size (around 5-7cm in length, with females being larger than males), the black markings on its side and back and, most reliably, the disgusting odour that it emits when it feels threatened (which is said to smell very similar to the chemicals used by American Minks to mark their territories, but is more often likened to rotting onions.) Preferring cooler climates than many other species in its genus, the Mink Frog can be found in eastern Canada and the northeastern USA, where it mostly inhabits permanent wetlands (although in periods of dry weather it may also be found in damp forests.) During the mating season, which lasts from late May to August, large numbers of male Mink Frogs gather in lakes, ponds and slow-moving streams where they float on surface or rest on aquatic vegetation and produce harsh, cluck-like calls to attract females - females prefer males with louder calls and more vivid colours. Females lay clusters of 400-5000 eggs in deep bodies of water and allow the eggs to sink to the bottom where they will be concealed by dense plant coverage until they hatch a few days later. Mink Frog tadpoles feed largely on algae and take around a year to develop into froglets, at which point they transition to a diet of invertebrates such as spiders, snails, dragonflies and aquatic beetles (male Mink Frogs are fully developed after just slightly over a year, while females take 2 years to reach maturity due to the larger sizes they reach.) Like most frogs that inhabit areas with temperate climates, Mink Frogs survive the winter by hibernating at the bottom of deep bodies of water.

Bad photo but some pool filter rescues from the farm! A mink frog and an American toad or quite possibly a Fowler’s toad! I’m thinking American because the bumps are more raised but if anyone can let me know I’d love that! Enchanted w Ontario’s frogs and toads
