Fish with Teeth:
* Predators: Most fish that are carnivores or omnivores have teeth. This includes:
* Sharks: Known for their rows of sharp, replaceable teeth.
* Barracuda: Have long, sharp teeth in their jaws.
* Pike: Have sharp, needle-like teeth for catching prey.
* Eels: Have rows of small, pointed teeth.
* Grouper: Have powerful jaws with strong teeth for crushing prey.
* Snapper: Have sharp teeth for tearing flesh.
* Herbivores: Some herbivorous fish have teeth, but they're often flat and used for grinding algae and plants.
* Parrotfish: Have beak-like teeth for scraping algae off coral.
* Pufferfish: Have strong, beak-like teeth for crushing hard-shelled prey.
Fish without Teeth:
* Some species: A few fish, like catfish, lack teeth in their mouths but may have teeth in their throats.
* Filter feeders: Fish that primarily eat plankton or tiny organisms usually don't have teeth, such as:
* Whale sharks: Filter feed with their gills.
* Sardines: Filter feed with their gill rakers.
Fun Fact: Fish teeth are often quite different from human teeth and can be replaced multiple times throughout their lives.
