- Seals A-Hunting shows a technique whereby the seal rests on the ocean bottom and looks for prey.
- In about 30 hours of letting a gopro run in that area I have only seen a few fish: C-O Sole, Staghorn Sculpin, Crescent Gunnel and a tiny tidepool sculpin. Also Dungeness Crabs were occasionally seen.
- Of interest is some fish, such as Salmon, are known to be able to detect the odor of a seal in the water.
- Studies have shown they can detect the presence of a seal diluted to one eighty billionth of water volume. This is about two-thirds of a drop in an olympic sized swimming pool (Jonathan Balcombe “What a Fish Knows”).
- Of interest is I noted both fish and crabs were more evident when the seals were not around.
- Harbor seals are known to be able to spend up to 20 minutes underwater. Most of the ones I saw resting on the bottom stayed there for less than 10 minutes.
