PPT Slide
- Some oceanic lifestyles
- pelagic-lives in water column
- plankton-cannot swim against current
- nekton-can swim against current
- motile-actively mobile
- sessile-attached to substrate
- benthic-lives on bottom
- epifaunal-lives on bottom
- infaunal-burrows beneath the bottom
- interstitial meiofauna-lives between grains of sand
- filter feeder-filters suspended material out of water column
- suspension feeder-filters organic food out of bottom “muck”
- Carnivores, endoparasites, ectoparasites, etc.
- Many oceanic forms have separate larval and adult phases which live different lifestyles;
- for instance, barnacles have motile, planktonic larvae, but attach to rocks and become sessile filter-suspension feeders as adults
