Preliminary observations on the movement ecology of a crested horn shark (Heterodontus galeatus)

The residency and movements of a single acoustically tagged female crested horn shark (Heterodontus galeatus) were monitored in Jervis Bay, Australia. The individual was intermittently detected by receivers throughout the 8-year study period and showed preference for particular rocky reefs in terms of its residency indices and duration of residency events. This individual exhibited lower residency and dissimilar movement patterns to that of the well-studied and sympatric Port Jackson shark (Heterodontus portusjacksoni), highlighting the need for research into the basic life history and movement ecology of H. galeatus.

Automated summary

The residency and movements of a single acoustically tagged female crested horn shark were monitored in Jervis Bay, Australia. The individual showed a preference for particular rocky reefs and exhibited different movement patterns compared to the well-studied Port Jackson shark. This highlights the need for further research into the basic life history and movement ecology of the crested horn shark.
