1. There are a few other permanent pelagic denizens which ecologically are less important, including the beautiful nautiloids - ancient cephalopods, which still retain the primitive, gas-filled shell; the turtles and sea-snakes; and the herbivorous sirenians - the dugongs and marine manatees of the tropics, which (probably!) are distantly related to the elephants.
2. The pelagic zone
3. Of the pelagic animals, some fish browse directly upon the plankton, as do the baleen whales, which concentrate upon the euphausiids and copepods.
4. Like the pelagic trilobites, individual graptoloid species are very widespread, which is what one would expect of an animal with the wide ocean as its habitat.
5. But their displacement from a dominant role in the pelagic habitat may have accompanied the rise of squid, sepioids, and octopods.
6. This is the pelagic zone (from the Greek, pelagikos , meaning "of the sea").
7. They travel in large concentrated groups to search for food, particularly when herding shoaling pelagic (open sea) fish.
8. The pelagic zone contains, in brief, the swimmers.
9. They became masters of the pelagic realm, possibly swimming in schools like their distant relatives the squids.
10. By restricting the maximum length of pelagic gill-nets in the Australian EEZ to 2.5 km (1.6 miles), they effectively excluded the huge Taiwanese nets.
11. A new and successful innovation was the evolution of stemless crinoids - some of these acquired pelagic habits, and during the Cretaceous the genera Marsupites and Uintacrinus ( see p.79) were widespread enough to be useful marker fossils.
12. Like living pelagic animals they had preferences for particular water temperatures; different types of ammonoids were found in high or low latitudes.
13. Many field studies suggest that the social structure of both inshore and pelagic dolphin species is generally fluid and loose, with probably a promiscuous mating system for most.
