Velryb\u00ed biolog Shane Gero byl prvn\u00ed, kdo si v\u0161iml neobvykle klidn\u00e9ho chov\u00e1n\u00ed u zn\u00e1m\u00e9 skupiny vorva\u0148\u016f (“jednotka A”) pobl\u00ed\u017e hladiny Karibsk\u00e9ho mo\u0159e. Velryby nekomunikovaly a neodpo\u010d\u00edvaly obvykl\u00fdm zp\u016fsobem, a pak se najednou za\u010daly pot\u00e1p\u011bt a koupat se ve vod\u011b.
