Beaver

Beaver

Castor canadensis

Size: 3-4 ft ( total length )

Habitat: in and around water

Notes:
Famous for their dam-building habits, beavers were once a major ecological force in North America, reshaping a very large proportion of the land to suit themselves. Unfortunately for them, they also became a major economic force - much of the early exploration of the continent was done by fur trappers. Today, beavers are rare, and virtually non-existent in New Jersey, although there are a few colonies.

Northern Coral
Astrangia danae

Most tropical corals contain photosynthetic algae which provide a substantial amount of the polyp's food. White Encrusting Coral, also known as Northern Stony or Star Coral, contains no such algae and therefore can survive the low light conditions and temperatures of the North Atlantic where other corals would die. Instead, it is a filter-feeder, much like an anemone.

Corals are similar to anemones in many ways. Each coral polyp is like an anemone in a stony cup. Many corals are colonial ( as are some anemones ) sharing a single merged body among many polyps.
