Coastal Migrations: Bull sharks commonly undertake coastal migrations along shorelines and estuaries. They move between coastal waters and river systems, often following seasonal changes in water temperature, salinity, and prey availability.
Estuarine Migrations: Bull sharks are known to migrate within estuarine systems, moving between the lower reaches of rivers and brackish waters to take advantage of changing environmental conditions and food sources.
River Migrations: Bull sharks have been found to migrate up rivers, sometimes traveling hundreds of miles into freshwater habitats. This behavior is more common in some regions than others and is influenced by factors such as water flow, prey availability, and habitat suitability.
Long-Distance Migrations: Bull sharks are capable of long-distance migrations across open oceans. They have been tracked traveling thousands of kilometers between different regions, including between the Atlantic Ocean and the Indian Ocean, or between the Pacific Ocean and the Caribbean Sea.
Individual Variation: Migration patterns can vary among individual bull sharks, and their movements are influenced by a combination of factors including age, sex, size, and environmental conditions.
It's important to note that bull sharks are relatively opportunistic and adaptable in their movements. They may alter their migration patterns or travel routes based on food availability, water quality, temperature changes, and other environmental cues.
