Answer:
Step-by-step explanation:
Lionfish and Nassau grouper are known to compete for shelter . As the lionfish population increases, it is likely that the Nassau grouper population will be affected. A study found that Nassau grouper avoided lionfish in two distinct ways; (1) groupers positioned closer to and used limited shelter more when paired with similarly sized lionfish and (2) grouper moved much further away from shelter when paired with smaller lionfish 1. This suggests that competition for shelter between these two species may be size dependent .
