WA crayfish are about to turn in unison and head for deeper waters on ‘whites run’

Millions of crayfish are set to descend into deep waters off WA’s coast this week, in a “unique” migratory march. The annual “whites run” is a natural phenomenon in which juvenile western rock lobsters from Bunbury to Kalbarri moult their red shells, becoming pale and soft. They then turn to exactly 283 degrees north-west and move from shallow coastal reefs to deep water. “And once they get into that loop and current, they turn and walk into the current and they walk northwards.” Dr de Lestang said lobsters tapped into magnetic forces in much the same way as homing pigeons. >click to read< 15:55
