Atlantic Coast leopard frog (2014)
In the early 2010s, biologist Jeremy Feinberg heard a leopard frog call in New York City-area wetlands that did not match known species. Genetic analysis showed it was a distinct species, Lithobates kauffeldi, found along the dense Atlantic coast corridor.
The 2014 description made international news as a new amphibian found near New York City.
It became a case study in how DNA analysis reveals species that physical inspection missed in supposedly well-known urban regions.
Like the sea spiders, this species was found close to major cities through careful genetic work, showing how DNA analysis overturns the assumption that well-surveyed regions are fully catalogued.
