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
Test your knowledge of fish habitats, including freshwater, saltwater, and brackish water environments, and their diverse diets, ranging from plankton to small fish and invertebrates.
