Swarms of jellyfish have descended on Egypt's northern coast, keeping vacationers out of the water and stirring debate over a recent expansion of the Suez Canal. The nomad jellyfish, Rhopilema nomadica, is native to the Indian Ocean and the Red Sea but has been turning up in the Mediterranean in growing numbers in recent years. The jellyfish have come through the Suez Canal, which was first built in 1869. Egyptian officials deny the recent expansion is to blame, noting that the jellyfish turned up in the Mediterranean as early as the 1970s. "The primary cause of the invasion of jellyfish is the Suez Canal," said Jason Hall-Spencer, a marine biologist at Britain's Plymouth University.
