New Jersey Scuba Diving

Triggers, Puffers, & Sunfish

Although it seems unlikely, these fishes are all related in the Order Tetraodontiformes. Common characteristics include:

  • teeth fused into horny beaks
  • tough leathery skin
  • swimming primarily with dorsal and anal fins rather than tail
  • pelvic fins lacking

They are all also possessed of rather higher intelligence than most fishes.

Gray Triggerfish

Gray Triggerfish

Balistes capriscus

A Profile
by Stacey Reap

Range:
The Gray Triggerfish is found on both the eastern and western Atlantic coasts. Along the Atlantic coast of North America, it ranges from Nova Scotia and Bermuda to Argentina, including a presence in the Gulf of Mexico and the Caribbean Sea. Most of the approximately 40 other species in the Balistes family can be found in tropical seas worldwide.

Planehead Filefish

Filefish

Stephanlepis hispidus

Size: to 10"

Habitat: wherever the current takes them

Notes: Baby Filefishes of 2"-3" may be found drifting along with clumps of Sargassum weed. They are also found inshore.

Ocean Sunfish

Ocean Sunfish

Mola mola

Size:
to 10 ft long, 11 ft tall, 4400 lbs,
but usually 4-5 ft long

Habitat:
Open ocean, usually basking near surface. This giant, slow-moving creature flaps along at the surface, propelled by its oar-like dorsal and anal fins and steering with the stump of its tail.

Puffers, Burrfishes & Trunkfishes

Northern Puffer
Northern Puffer - Sphoeroides maculatus to 14", usually much smaller

Puffers are highly intelligent, traveling in schools, and hunting cooperatively. They prey on anything they can dismember with their powerful parrot-like beaks, including other fishes and crabs. The body is short, fat, and stiff, with a disproportionately large head.

Density & Specific Gravity

Specific gravity is the ratio of the density of a material to the density of water. Materials with a specific gravity greater than 1.000 ( 1.035 in the ocean ) sink; materials with a specific gravity less than 1.000 ( 1.035 in the ocean ) float. Lead has the highest specific gravity - 11.35, except for gold. Gases like air also have weight, density, and specific gravity.

These figures are approximate and should be used only as general indicators.
