classification
Fish, Actinopterygii, Clupeiformes, Clupeidae, Genus Sardinops (Sardinops sagax for Pacific Sardine)
habitat
Sardines are typically found in coastal waters of the Pacific and Atlantic Oceans, often in large schools near the surface. They prefer nutrient-rich waters and are commonly associated with upwelling zones where they feed on plankton.
body length
Sardines generally range from 15 to 30 cm in length, depending on the species. For example, the Pacific sardine (Sardinops sagax) can grow up to about 30 cm, while the European sardine (Sardina pilchardus) typically averages around 20 cm.
body weight
The average weight of sardines varies by species and age, but they typically weigh between 50 to 200 grams. Adult Pacific sardines can weigh up to 250 grams.
lifespan
The lifespan of sardines is generally between 3 to 7 years. Factors such as environmental conditions and predation can affect their longevity.
food habit
Sardines are filter feeders that primarily consume plankton, including phytoplankton and zooplankton. They use their gill rakers to filter these tiny organisms from the water as they swim.
habit
Sardines are known for their schooling behavior, often forming large, tight-knit schools for protection against predators. They tend to remain near the surface of the water and are more active during the day.
natural enemy
Sardines have several natural predators, including larger fish (like tuna and mackerel), seabirds, and marine mammals such as dolphins and seals. Their schooling behavior helps reduce individual predation risk.
bits of knowledge
Sardines are an important part of the marine food web and are also a significant fishery resource for humans. They are often canned or processed for consumption. Sardines are rich in omega-3 fatty acids, making them a healthy dietary choice.
