Figure 4:

Impact of ocean warming and acidification on the behavioural patterns of adult seahorses, H. guttulatus. (A) Rest, which includes ‘inactive’ and ‘swinging’ behaviours. (B) Activity, which includes ‘feeding’ and ‘swimming’ behaviours. Values are shown as means + SD (n = 6). Different letters and asterisks represent significant differences (P < 0.05) between temperature and pH conditions, respectively. Lower case letters are used for differences between temperatures at pH 8.0 and upper case letters for differences between temperatures at pH 7.5.
