Triggers, Puffers, & Sunfish

Well, it's that time of year again, time to renew the web hosting. And for those of you that don't know, that has become a lot more expensive than it used to be. Fifty dollars a year is now several hundred. Not to mention the price of domain names has gone up ten-fold.

And I just found out that the nice folks at PayPal disabled all my Support buttons, and I never got a notice (although that may be my fault.) In any case, it is all working again now, so if you would like to make a small donation to help defray these costs, it would be greatly appreciated.

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

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.


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

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.


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.


"Higher animals" is a catch-all term for vertebrates other than fish. This is rather self-congratulatory, since the so-called "lower animals" - fishes and invertebrates - are actually the dominant species on the planet, both in numbers and diversity! The four classes of higher animals are:

  • Amphibians - class Amphibia
  • Reptiles - class Reptilia
  • Birds - class Aves
  • Mammals - class Mammalia

Of these, amphibians are absent from marine environments ( with one or two exceptions. )
