New Jersey Scuba Diving

River & Inlet

These fishes are most likely to be found on or near the bottom in the rivers and inlets, either resting or swimming around. In addition, many of the types more often found out at sea may be found in the rivers and inlets. In addition, many tropical fishes may be found here as well.

Many of the types presented here are representative of entire families of similar related species. While some are closely related, others are not. These particular species are the most common in our area.

Oyster Toadfish

Toadfish

Opsanus tau

Size: to 15"

Habitat:

Generally inshore on hard bottoms and in shellfish beds, in 30-40 foot depths.

Longhorn Sculpin

Myoxocephalus octodecimspinosus

Sculpin

Size: to 18"

Habitat: Generally inshore in harbors and inlets, in 30-40 foot depths, but moves out to deep waters in winter.

Notes:

Sculpins have sharp spines around the head area - best to leave them alone. Sculpins are capable of loud vocalizations. Grubby is similar but smaller with a more rounded tail.

Naked Goby

Naked Goby

Gobiosoma bosci

Size: to 2-1/2 "

Habitat: bays, estuaries, protected coastal waters

Notes:

This is a funny little fish that prefers to hide under oyster shells and the like. Named for its complete lack of scales.

Feather Blenny

Feather Blenny

Hypsoblennius hentzi

Size: to 5"

Habitat: bays, estuaries, protected coastal waters

Notes:

Blennies live on the bottom in oyster beds or mussel beds. If you find an old piece of pipe or a bottle in the river, look inside - you'll probably find a blenny.

Inshore Lizardfish

Lizardfish

Synodus foetens

Size: to 18"

Habitat: almost anywhere, but favors shallow waters

Notes:

You will find these at night in the river, perched on their fins, with alligator-like jaws studded with teeth waiting for some unfortunate killy to come by. Spook it, and the Lizardfish will dart away too fast to see.

Northern Pipefish

Pipefish

Syngnathus fuscus

Size: to 12"

Habitat: Weedy protected shore waters.

Notes:

The Northern Pipefish is the only common inshore species in our area. Pipefishes are closely related to Seahorses and found in the same kind of habitats. They lack the seahorse's prehensile tail but are much better swimmers than their coiled cousins.

Lined Seahorse

Seahorse

Hippocampus erectus

Size: to 6"

Habitat: Weedy protected shore waters.

Notes:

Look for Seahorses in still weedy areas, where they cling to plants and objects with their prehensile tails. Color and body form are highly variable, as these masters of camouflage adapt to their surroundings. Strays may be found at sea, or even washed up on the beach.

Sticklebacks

Sticklebacks

Gasterosteus aculeatus
( Threespine, right )

Apeltes quadracus
( Fourspine, below )

Size:
to 4" (threespine)
to 2" (fourspine)

Sticklebacks

Habitat:
Weedy shore waters, occasionally at sea or even in freshwater.

Notes:
Sticklebacks are related to Pipefish and Seahorses. Three- and four-spined varieties are common in our area. A Ninespine variety is also possible.

The Buddy System Re-examined

Sept. 1996

PARALLELS ARE OFTEN DRAWN BETWEEN DIVING AND FLYING. Both take place in an environment where the ambient pressure is different than the earth's surface - where we spend most of our time breathing - and both require formal training to qualify as a participant. Yet, on one point the two activities diverge completely. In flying, the highlight of a pilot's life is his or her first opportunity to solo - to operate the aircraft alone. In fact, after earning a private pilot's license, aviators commonly fly with no one other than God as their copilot.

Not so in diving; the admonition to "never dive alone" is considered the hallmark of safe diving.

To most divers, entering the water without a buddy is tantamount to a pilot taking off without doing a preflight check of the airplane. But to assume that buddy diving is an absolute universal practice would be a mistake. Lots of divers dive solo. Some do it intentionally, but most end up sans buddy completely by accident.
