Basking shark occurrence off south‐west England in relation to zooplankton abundance

Basking sharks Cetorhinus maximus >3 m total length arrived off Plymouth, U.K. directly after the increase in zooplankton density in May, while young‐of‐the‐year basking sharks (<3 m) occurred when zooplankton density was lower (0·8‐1·1 g m−3). No basking sharks were seen after July when the zooplankton density was least.
