Landons Bay | Bullhead Fish ___ 03_SZN9895-Enhanced-NR-1-1 copy

            Landons Bay | Bull Heads and Frogs 
 
On a recent windless day and low water flow conditions, silk and organic matters settled in a rather small pond framed by two beaver dams, revealing captive, now cohabiting Bullhead Fish and American Bullfrogs that may not have been so friendly to each other in the earlier times of their lives. Brown Bullhead Fish, aka Mud Pouts or Mud Cats, about 15 cm in length, and described as bottom feeders known to survive in low oxygen environments, are shown here in somewhat latent stages sharing the same aqua-spaces with American Bullfrog Tadpoles. The Tadpoles were all about the same size (perhaps ~10 cm in length) and in similar stages of development with hindlegs developing whereas the forelegs may not have begun to grow, suggesting they may have hatched in the spring of last year and are not yet adapted to life on land. In our area, Bullfrogs may spend one or two years in the tadpole stage. This life stage will be followed by the tadpole’s long-drawn-out metamorphosis that will see the tadpole transform into a froglet by growing hindlegs, then forelegs and develop lungs to replace its gills to take in oxygen. Over time the froglet will loose its tail. However, contrary to popular beliefs, frog tails do not drop off. Instead, the tail is slowly absorbed by the growing froglet through the process of apoptosis. Indeed, the tail serves as a food reserve for times when available nutrients from the environment are scarce such as in late fall and the winter months. In Southern Ontario, it may take 3 years for Bullfrogs to fully develop into their adult stage.
