Norway Rat

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.

Horned Salp

Thalia democratica

Although they may superficially resemble swimming siphonophores, salps are actually free-living tunicates. There are 6 genera of salps and all are transparent.

Tunicates are much more advanced in the evolutionary scheme of things than jellyfishes, having, for example, a circulatory system. The larvae actually even have several features in common with vertebrates, including the precursor of a spinal cord, but these are lost in the sac-like adults. Salps do not sting.
