Relationship between water temperature and snail growth. a) Small snails. b) Medium snails. c) Large snails. Small, medium and large snails were defined as snails with a shell diameter at the start of the fortnight of < =8 mm, >8 mm & < =10 mm, and >10 mm respectively. Lines show the best fit linear and quadratic relationships, fitted to data from both sets of experiments combined.
