Northern Leopard Frog

Lithobates pipiens

Description:

Northern leopard frog spotted at a study site in western Iowa. The last photo shows a Visible Implant Alphanumeric Tag which was inserted under the thin skin in the hind foot. These tags are a relatively new way to mark small animals, such as fish and frogs, for mark-recapture studies.

Habitat:

The northern leopard frog is the most cold-adapted of all the leopard frogs. They live in the vicinity of springs, slow streams, marshes, bogs, ponds, canals, flood plains, reservoirs, and lakes; usually they are in or near permanent water with rooted aquatic vegetation.

Mike, the tagged is placed by first making a small incision in the thin top layer of skin under the hind leg and injecting the little tag with the VI alpha tag injector. The tags are fluorescent and glow when using the VI light (essentially a black light flashlight). There is a liquid form of visible implant elastomer tags which is also really cool. I've added a link which explains both of these if you're interested in knowing more :)

Cool Marylou! Interesting! How do you put the tag on the frog's foot?
