I was walking on the Boardwalk looking at the marshy area below as it is a frequent place to see birds. I was surprised to see a large number of these tadpoles. Given their size, I assume they are from an American Bullfrog (Lithobates catesbeianus). Perhaps I will find out if any survive through metamorphosis. On a subsequent visit a week or two later, many of the tadpoles were still there. Sitting among the tadpoles was an adult frog, shown below.

American Bullfrog mostly submerged in the shallow water. Abundant water plant life is around the frog.
