Tidal Flats

Tidal flats are a substantial resource harboring a variety of species, including clams, quahogs, marine worms, lobster larvae, and crabs. These resources are endangered by polluted water runoff from residential and commercial activities.

The video clip below shows clam survey activity and small crabs scampering under an incoming tide during an educational event in 2012. The green crabs are an invasive species that consume clams, especially the young, and are said to be responsible for the recent decline in that resource. The next ceature shown is a hermit crab, so-called because they “borrow” snail and other shells as their homes. When they outgrow a shell, they seek a larger, better fit.
