    Study Notes

    Habitat

    • Fish can be found in various aquatic environments, including:
      • Freshwater habitats: rivers, lakes, ponds, and wetlands
      • Saltwater habitats: oceans, coral reefs, and estuaries
      • Brackish water habitats: mangroves, swamps, and deltas
    • Fish habitats can be characterized by:
      • Water temperature: ranging from near-freezing to warm tropical waters
      • Water chemistry: varying levels of oxygen, salinity, and pH
      • Substrate: including rocks, sand, mud, and vegetation

    Diet

    • Fish are omnivores, carnivores, or herbivores, depending on the species
    • Fish diets can consist of:
      • Phytoplankton and algae
      • Zooplankton, such as crustaceans and insects
      • Small fish, eggs, and larvae
      • Invertebrates, like mollusks and crustaceans
      • Detritus and organic matter
    • Some fish have specialized feeding behaviors, such as:
      • Filter feeding: using gills to capture food particles
      • Benthic feeding: feeding on the seafloor or lakebed
      • Pelagic feeding: feeding in the open water column
