ZANZIBAR, Tanzania (AP) -- Scientists tried to discover Saturday why hundreds of dolphins washed up dead on a beach popular with tourists on the northern coast of Zanzibar.

A preliminary examination of their dolphins stomach contents failed to show the presence of squid beaks or other remains of animals hunted by dolphins.
That was an indication that the dolphins either had not eaten for a long time or had vomited, Jiddawi said.
Their general condition, however, appeared to show that they had eaten recently, since their ribs were not clearly visible under the skin, she said.
Although Jiddawi said Friday that poisoning had been ruled out, experts were preparing to further examine the dolphins' stomachs for traces of poisonous substances such as toxic "red tides" of algae.
