Jacksmelt

---

Topsmelt (Atherinopsis californiensis) are native to the west coast of North America, ranging from Baja California, Mexico to Oregon. Like their closely related cousins, the topsmelt, jacksmelt have blue-gray to green coloration on their backs and silver bellies with an eye-catching stripe along their sides and thin, elongated bodies. Compared to topsmelt, though, this species is larger, potentially growing up to 22 inches and has a bright yellow operculum. Jacksmelt prefer nearshore open water habitats and favor an omnivorous lifestyle with a preference for carnivory. Like topsmelt, they are important prey fishes for numerous marine species including larger fishes, large mammals like sea lions and seals, and sea birds.

Fun fact: Contrary to their name, jacksmelt are not true “smelt” but are actually neotropical silversides.
