World Data Ocean keeps habitat use in one place: 3 stories so far. The section currently leads with “Tracking Shark Movements Reveals Insights for Marine Sanctuary Protection”, “Stable Isotopes Illuminate Feeding Patterns Before Scottish Whale Stranding”, and “Hawaiian Blacktip Sharks Reveal Coastal Nursery Habitat Use”. Silky sharks favor natural banks in winter and spring, then shift to artificial reefs in summer. When 55 long-finned pilot whales stranded in Scotland in July 2023, the event became more than a tragedy; it became a scientific dataset. A Global Hub for Ocean Intelligence 4 World Data Ocean is a centralized digital platform where researchers, scientists, and ocean enthusiasts converge to… The list below is every habitat use story on World Data Ocean, newest first.
Tracking Shark Movements Reveals Insights for Marine Sanctuary Protection
Silky sharks favor natural banks in winter and spring, then shift to artificial reefs in summer. Sandbar sharks, by contrast, remain year-round across both habitats, with nearly half detected beyond sanctuary boundaries. These empirical, real-time data reveal that Flower Garden Banks cannot function as an isolated refuge. Protection must account for the integrated ecosystem these sharks actually use.

Stable Isotopes Illuminate Feeding Patterns Before Scottish Whale Stranding
When 55 long-finned pilot whales stranded in Scotland in July 2023, the event became more than a tragedy; it became a scientific dataset. By analysing carbon and nitrogen stable isotopes across liver, skin, and muscle from 39 individuals, researchers found no consistent evidence of recent dietary or habitat shifts. This matters. The absence of a detectable trophic-level change, despite varied tissue integration timescales, sharpens our understanding of what stranding events can and cannot tell us.
Hawaiian Blacktip Sharks Reveal Coastal Nursery Habitat Use
Hilo Bay has quietly claimed a significant distinction: it is the first documented blacktip shark nursery habitat in Hawai'i. Over 18 months, acoustic tracking of 29 juveniles revealed year-round residency, with peaks from March through August. What stands out is the role of dissolved oxygen, which appears to shape when and where these sharks move. This is empirical, measurable evidence that coastal habitats deserve closer scrutiny. Understanding these patterns strengthens our ability to protect the spaces where young sharks begin their lives.
