Fig. 42: Three orcas and a fishing boat. The orcas come to the Strait of Giraltar every year from July to August, because that is when the fishermen of Spain and Morocco catch the tuna swimming out of the Mediterranean Sea with long fishing lines. The animals have noticed that someone else is doing the tedious work of catching them for them. In addition, tuna are usually too quick for the orcas. They wait for the tuna to bite, tire and be pulled up by the fishermen before nibbling them off the line in a flash. They knowingly leave the heads with the fishing hooks behind. — Strait of Gibraltar Nikon D200; Δt=1/1000 s; f=200 mm; f/5.0; ISO 200; 28 July 2006 11:56:40
