New Jersey Scuba Diving

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.

Rattus norvegicus

Size: 6-8" (body)

Habitat: everywhere

Notes:
Sorry to say, but rats are especially common around watery habitats and are excellent swimmers. They are particularly fond of beaches, marshes, ships, docks, and jetties. The next time you go diving at Shark River, take a careful look in the rocks and you will likely see one or two scampering around, dining on old fishing bait and washed-up detritus, even in broad daylight. The Norway Rat is introduced from the Old World, and in most areas today it is more common than the native Black Rat.
