    This activity will help students to grasp one aspect of pea crab biology – the risky journey of a male pea crab (a parasite of green-lipped mussels) to locate a female crab in another mussel and fertilise her eggs. The card game works as a model of the mate location process. It helps students to explore why scientists think pheromones are likely to be important in the crab’s reproductive strategy. The activity also provides a good introduction to discussions about the future biocontrol of pea crabs, which may involve the use of crab pheromones.
