Norway Rat
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.
An assortment of mammals that might be observed in and around the water.
