Feeding time at the Aquarium's Open Sea exhibit is for many people the highlight of their visit to Monterey. The largest tank at the Aquarium provides enough space for the different fish species to co-exist. The school of sardines, prey species for the Pacific blue tuna, spend most of their day at the bottom of the tank and only during feeding they move upwards and show their marvellous capacity to move as one entity. See how they, after being fed, avoid the predator fish and move downwards again when the predators get their meal. It seems that, now and again, the more careless sardines end up in the predators' stomachs.Unfortunately the video is a little dark and contains some camera-flash from other visitors, but it does show how the school of sardines move as a cloud through the exhibit.
