Higher Animals

"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. )


Diamondback Terrapin

There are few marine reptiles and even fewer in the cold North Atlantic. While it would be possible for a salt-water crocodile to swim up from the Caribbean, there is no record of one ever having done so. Nor are there any of the sea-snakes that are famous in the South Pacific. The only marine reptiles that are encountered in our waters are sea turtles.

The one exception to this is the little Diamondback Terrapin, Malaclemys terrapin. (right) This small turtle ( about 6 inches ) is found only in salt marsh environments. Adults are very strong swimmers and have even been noted in the ocean surf, although I don't think they venture offshore.




fish trap
A fixed fish trap. The curtain nets stretch from surface to bottom, and the fish are funneled into holding areas.

Fish traps are only practical in shallow water. They have the advantage of keeping both the targeted catch and the bycatch alive ( unless a shark gets in ! ) You can still see a few fish traps in use in Raritan Bay, where they are built around fixed pilings rather than buoys and anchors as shown here. In years past, shore-based trawling or "haul seining" was also practiced in the bay, where a net would be deployed off the beach by a small boat, and drawn in by donkeys or trucks.
