We evaluate the hypothesis that the vertical migration of Periphylla periphylla is governed by its sensitivity to light intensity. By applying an individual-based model where random walk is combined ...
Vertical migration of the mesopelagic jellyfish Periphylla periphylla (Scyphozoa: Coronatae) was studied by use of hull-mounted and submerged echosounders in a ~440 m deep Norwegian fjord. The researc...
