Feeding on survival-food: gelatinous plankton as a source of food for anchoviesy transfer in the marine trophic web, and often it is assumed that such soft-bodied fauna are trophic ‘dead ends’ in the food webs. In recent years, however, it has been shown that many fish species feed extensively on gelatinous zooplankton, while other species may feed on them occasionally when ot

The impact of El Ni?o events on populations of mesopelagic hydromedusaes of Monterey Bay, CA in order to elucidate patterns in midwater ecology. Two El Ni?o events have occurred during this time period, in 1991–92 and in 1997–98. The oceanographic metric of spiciness combines temperature and salinity data into one sensitive measurement. Although temperature and salinit

Jellyfish swarms, tourists, and the Christ-childlake in Palau, Micronesia. This ‘Jellyfish Lake’ became a popular off-gassing stopover for SCUBA divers and a destination in its own right for non-diving tourists in the mid-1980s. Since then, tourism in Palau has boomed, increasing 500% between 1986 and 1997. However, in December 1998, the golden-m
