Kyra set up her “HerbivoreCams”. They consist of 10 small video cameras set on the reef at 40m (and 10m) which record the activity of herbivorous fish in a series of “quadrats” or study sites. Herbivorous fish have been found to be very important in shallow coral reefs – without them the reef can quickly become overgrown with marine algae. The team hopes to find out whether the same applies at lower depths.
