According to my sources, waves can be destructive/constructive and cause a strong force, which sweeps away substances on the shore. Therefore, limpets require height to counteract these forces. Liverpool Hope University College suggest that: ‘The results show that there is a difference
in size between limpets present on the upper and lower shore, with larger limpets generally
found on the upper shore.’ This support my results since Limpets on the upper shore had a greater height overall in comparison to the middle shore. Other experiments show that ‘the smallest limpets found on the shore were on the middle shore’. They found that,’ on the lower shore, the limpets had the smallest height but the largest width.’ This may be due the fact that the limpets on the lower shore needed to hold on to prevent them from being swept away. By having a greater width
