The swim bladder is large, allowing for minimal energy expenditure while cruising or remaining idle. [5] Heller's barracuda . In most cases, barracuda are dark gray, dark green, white, or blue on the upper body, with silvery sides and a chalky-white belly. Coloration varies somewhat between species.
The Pacific barracuda is found in the Northeast Pacific Ocean, typically offshore of the U.S. West Coast.While it is usually considered a pelagic species, and can could be found as far north as southern Alaska, they are most frequently found along the coast of California extending down to the southern tip of Baja California Sur, Guadalupe Island and near the mouth of the Gulf of California.
Sphyraena barracuda, commonly known as the great barracuda, is a species of barracuda: large, apex predator ray-finned fish found in subtropical oceans around the world. The Syphyraena family contains 27 species while the great barracuda is one of this genus.
The ocean's primary producers, mainly contained in phytoplanktons, produce food energy and biomass photosynthetically from sunlight and are the raw fuel for the ocean food webs. Forage fish transfer this energy by eating the plankton and becoming food themselves for the top predators. In this way, forage fish occupy the lower-central positions ...
Sphyraena viridensis, the yellowmouth barracuda or yellow barracuda is a predatory ray-finned fish from the family Sphyraenidae, the barracudas. It is found in the warmer waters of the eastern Atlantic Ocean and the Mediterranean. It is often confused with the European barracuda.
The “rarely seen” predators were spotted off the California coast near San Diego. Boaters witness ‘unbelievable spectacle’ when predators attack sea creature. See it
The Australian barracuda is greenish on the back, silvery on flanks which fades to white on the belly with a greenish-yellow tail. It has the typical fusiform shape of a barracuda, but it is slimmer than most other species of Sphyraena with a conical snout and a protruding lower jaw, the jaws are lined with fang like teeth and the upper jaw is non-protracting.
Consequently, the predators and prey will be locked in an evolutionary arms race, each looking to gain the upper hand on the other. The presence of fish predators play a large role in the size, shape and swimming performance of the Lithobates clamitans tadpoles. The presence of these predators in their habitat causes the tadpoles to develop ...
