Key Identification Features
- Larger, older males establish and defend distinct territories on the rookery.
- Territory boundaries are defined by natural features such as rocks, faults, or rock ridges, and territories can remain stable for up to 60 days.
- Unique, diagnostic features mark both the fore and hind flippers.
- No fur grows on the top of the fore flippers, which leaves a distinct abrupt "clean line" across the wrist where fur ends.
