Reptiles & Amphibians

An assortment of reptiles and amphibians that might be observed in and around the water. There are many other types as well. Except for a single species of frog, amphibians are absent from the marine environment.



Bullfrog

Rana catesbeiana

Size: to 6"

Habitat: prefers larger bodies of water

Notes: This big frog will eat almost anything that moves. They have been known to catch and eat birds.


Salamander

many species

Salamanders are terrestrial as adults, but eggs and larvae are aquatic. Larvae have both gill slits and external gills. A few species are completely aquatic, retaining these features as adults. Some salamanders are boldly colored and patterned and easy to identify, but many are simply small and brown and very difficult to tell apart, like this one.


Northern Water Snake

Nerodia sipedon

Size: to 42"

Habitat: in and around water

Notes: Not poisonous, but likely to bite if caught, with sharp, needle-like teeth. These snakes retreat into the water at the slightest disturbance, and are excellent swimmers, although they show no particular adaptations to it like oceanic sea snakes. Common small harmless Garter snakes are also often found around water. Most sport some variation of an attractive pattern of yellow/black stripes.


Common Musk Turtle

Sterotherus odoratus

Size: to 4.5"

Habitat: in and around water

Notes: Also known as 'Stinkpots'. Often bad-smelling, sometimes snappy, and a nimble climber. Occasionally, this little turtle is even found in trees.


Snapping Turtle

Chelydra serpentina

Size: to 15" (body)

Habitat: hides on the bottom in any type of water

Notes: Generally docile and easily approached in the water, but should be treated with respect for its powerful bite. This turtle can easily amputate a finger or toe and becomes pugnacious when landed. If you have the patience, try to see how long this turtle can go between breaths. A lot longer than you or me, that's for sure.


Painted Turtle

Chrysemys picta

Size: to 6"

Habitat: shallow water over muddy bottoms

Notes: Also known as 'Sliders'. Likes to sun itself on floating logs. Sliders are not native to New Jersey, but the descendants of released pets are quite common.


Common Atlantic Octopus

Octopus vulgaris

Size: see below

Habitat: rocks and coral reefs, all depths

Notes:

The Common Octopus is the most studied of all octopus species. Its natural range extends from the Mediterranean Sea and the southern coast of England to at least Senegal in Africa, as well as the Azores, Canary Islands, and Cape Verde Islands. In the western Atlantic, it ranges from Texas and Florida to New England, although uncommon in colder northern waters. Typical habitat is rocks and coral reefs. Young are planktonic, and total lifespan is only 12-18 months.

O. vulgaris grows to 25 cm in mantle length with arms up to 1 m long. They can weigh up to 20 pounds, although they are usually much smaller. O. vulgaris is caught by bottom trawls on a huge scale off the northwestern coast of Africa. More than 20,000 tons are harvested annually.
