Mink Frog (Lithobates septentrionalis), family Ranidae, Manitoba, Canada

The name comes from the smell of the frog, which is said to be similar to that of a mink. (The smell is also comparable to rotten onions).

Also called the "North Frog", it is found in the far north central and NE United States and eastern Canada.

Carpenter Frog (Lithobates virgatipes), family Ranidae, found along the Atlantic Coastal plain, from NJ to GA, in the U.S.

They prefer acidic aquatic environments, with ample sphagnum moss, such as bogs and fens.

The name comes from the frog's call, which resembles a carpenter hammering.

Crayfish Frog (Lithobates areolatus), family Ranidae, IN, USA

These frogs live underground, often in crayfish burrows.

Wood Frogs (Lithobates sylvatica), mating pair with eggs, family Ranidae, found across the northern and eastern parts of North America

NOVA: Frozen Frogs

In this video adapted from NOVA scienceNOW, learn how the common wood frog survives the cold winter. Wood frogs are found in the northern United States and Canada and must endure freezing cold temperatures for parts of the year. In order to survive the cold, they have a special adaptation—they are able to freeze solid without damaging their cells. Sugar acts like a natural antifreeze in their bodies, allowing them to spend the winter frozen and then resume function in the spring.

Green Frog (Lithobates clamitans), family Ranidae, Upper Peninsula, Michigan, USA

Chiricahua Leopard Frog (Lithobates chiricahuensis), family Ranidae, Arizona, USA

This species has been eliminated from 80% of its native range. It is considered threatened due to habitat loss, introduced species, and the chytrid fungus.

Gopher Frog (Lithobates capito), family Ranidae, South Carolina, USA

Do not garnish these eggs for an after-holiday snack. They’re the future of imperiled gopher frogs in South Carolina’s Francis Marion PARCA (Priority Amphibian and Reptile Conservation Area), and they’re more precious than any luxury snack. In the Francis Marion PARCA, gopher frogs lay their eggs in seasonal wetlands, but today, of the dozen or more historic breeding ponds here, only a handful still support gopher frogs. We’re changing that. We’re combing wetlands for egg masses and treating them like they’re as precious as a rare delicacy. When we find eggs, alongside our partners, we collect them and raise the tadpoles past their most vulnerable stages. Once they’re froglets, we return them to restored forest habitats near ponds. Farm-to-forest, not farm-to-table. We’re also restoring the ponds, clearing overgrown vegetation and, with our partners, reintroducing fire. For our team, those long hours don’t always come with immediate results. But then, sometimes, there’s a moment of payoff that makes it all worth it. “Finding gopher frog egg masses in newly restored ponds was one of those moments for me,” said Field Biologist Maddie Prickett. “While trying to conserve a species, there’s a lot of labor and effort that doesn’t always come with instant gratification. Many hours are put into restoring habitat, collecting eggs and raising tadpoles, analyzing acoustic recording data, and releasing headstarted [captive reared] frogs. But actually seeing the fruit of all of that is one of the most gratifying things.” Not caviar. Still priceless. And still worth all the effort to keep gopher frog recovery from slipping off the menu of conservation wins.
