Crabeater Seal

Capturing the Crabeater Seal requires equipment that can handle the extreme conditions of the Antarctic. If you are setting up a camera on an expedition vessel or near a coastal station, focus your lens on the edges of floating pack ice where the seals haul out to rest. Use a high-speed shutter—at least 1/1000th of a second—to compensate for the intense glare of the sun on white snow and to freeze the action of their surprisingly fast serpentine sliding motion.

For remote setups, lithium batteries are non-negotiable, as standard alkaline batteries will fail within minutes in sub-zero temperatures. Mount your camera on a weighted tripod or a specialized ice-screw mount to ensure it remains stable against the fierce Antarctic winds. Positioning the camera at a low angle (roughly 1-2 feet above the ice) will provide a more intimate, 'seal-eye view' that highlights their dog-like facial features and unique dental structure.

Since these seals are most active in the water during the night, use a camera with high-quality infrared (IR) capabilities if you hope to catch them near the water's edge at twilight. However, during the Antarctic summer's 24-hour daylight, you can rely on standard color sensors. Avoid using any artificial bait, as it is strictly prohibited under the Antarctic Treaty; instead, look for 'leads'—natural cracks in the ice—which serve as the seals' primary highways between the ocean and their resting platforms.
