Odontoscion
Odontoscion is a genus of fish in the family Sciaenidae, commonly known as drums or croakers. This genus comprises several species found in the coastal waters of the eastern Pacific Ocean, from Baja California, Mexico, to Peru. They are characterized by their elongated bodies, large mouths, and distinct sensory pores on their heads. The name “Odontoscion” translates to “tooth-shadow” and is a reference to their pointed teeth and the shadows they cast on the seabed.
Common Names
Species of Odontoscion are commonly referred to as "corvinas," "roncadores," or "sand bass," depending on the specific species and region. These names reflect their distinctive features and their presence in sandy bottom habitats.
Characteristics
Odontoscion species exhibit several common characteristics:
- Elongated body: They have a streamlined body shape, well-suited for navigating sandy environments.
- Large mouth: Their large mouths are equipped with rows of sharp teeth, used for capturing prey.
- Sensory pores: They possess a unique system of sensory pores on their heads, which help them detect vibrations and pressure changes in the water, aiding in prey location.
- Dorsal fins: They have two distinct dorsal fins, the first spiny and the second soft-rayed.
- Anal fin: Their anal fin is also soft-rayed and located behind the second dorsal fin.
Environment
Odontoscion species typically inhabit coastal waters, primarily residing in sandy and muddy bottoms. They are found in shallow waters and estuaries, but can also inhabit deeper environments, depending on the species. They are often associated with rocky reefs and seaweed beds, where they find shelter and forage for food.
