Sharks - Inshore

Here is an assortment of large sharks that can be found in New Jersey waters, by no means all of them. These are more likely to be found inshore in coastal waters. Sharks are seldom a danger to divers, they seem to be put off by the noise and bubbles. Nonetheless, all should be treated with caution.

In all my many inlet dives, I have seen a shark once, and that was in inoffensive Smooth Dogfish. I have been told that they are sometimes seen from up on the bridge in Belmar, but even then they would probably be out in mid-channel, and far away from strange noisy bubbling scuba divers. However, one of the most famous shark attacks of all time took place in New Jersey - the 1916 Matawan Creek attacks. See Bull Shark for details.

The only one of these that you are ever likely to encounter in local ocean diving is the relatively inoffensive Sand Tiger, not the similarly named and extremely dangerous Tiger.

This page has many spectacular photographs of sharks. That is because people are fascinated by these sleek and deadly predators, and there are many many great pictures on the internet to choose from. But don't be alarmed - your likelihood of encountering a dangerous shark in New Jersey waters while diving is near nil. If you note the water clarity in most of these pictures, you will realize that they were not taken anywhere near here!


Sand Tiger Shark

Carcharias taurus

Size:
to 11 ft

Habitat:
coastal waters

Notes:
dangerous
if provoked, usually unaggressive

Sand Tiger sharks have a broad inshore distribution. In the Western Atlantic, this shark occurs from the Gulf of Maine to Florida, in the northern Gulf of Mexico, in the Bahamas, and in Bermuda. The sand tiger shark is one of at least four species belonging to the family Odontaspididae. Synonyms include Carcharias taurus, Eugomphodus taurus, and Carcharias arenarius.


Tiger Shark

Galeocerdo cuvier

Size:
to 24 ft

Habitat:
open ocean, also enters rivers and bays at night

Notes:
extremely dangerous

tiger shark teeth

The serrated teeth are designed for sawing chunks from large prey items

If you are going to worry about a shark, let it be this one. Tiger Sharks are big, bold and inquisitive, and frequently come close inshore. They are also remarkably undiscriminating in their eating habits, which makes them even more likely to attack a swimmer, or anything for that matter.


Bull Shark

Carcharhinus leucas

Size:
to 12 ft, perhaps larger

Habitat:
coastal waters, bays, rivers, into freshwater

Notes:
dangerous

Bull Shark

The Bull Shark can be recognized by a combination of characters including a stout body, short blunt snout, triangular serrated teeth in the upper jaw, and no fin markings as an adult. This species has a second dorsal fin about one-third the height of the first, a small eye, and no skin ridge between the two dorsal fins. It is gray above and pale below, sometimes with a pale stripe on the flank.


Hammerhead Shark

Sphyrna lewini

Size:
to 13 ft

Habitat:
coastal waters

Notes:
dangerous

Hammerhead Shark

Sharks such as the Hammerhead, that have their eyes positioned on lateral extensions of their heads belong to the family Sphyrnidae. ( Sphyrna is Greek for hammer. ) Four species occur in the region:

  • Scalloped Hammerhead Sphyrna lewini - most common
  • Smooth Hammerhead, Sphyrna zygaena - most northerly
  • Great Hammerhead, Sphyrna mokarran - largest, mainly tropical
  • Bonnethead, Sphyrna tiburo - smallest

Atlantic Silverside

Menidia menidia

Size: to 7 1/2 "

Habitat: Generally inshore in harbors, inlets, and other quiet waters.

Notes: Forms large schools. Look for them swirling around the dive boat at the dock. More closely related to killifishes than herrings, Silversides are also found in freshwater.
