Can’t touch this! Drone aerial video shows it’s ‘hammerhead’ time


It’s “hammerhead” time according aerial drone footage of blacktip sharks fleeing to shallow waters when confronted by a huge predator along the coast of southeast Florida. Footage from the drone provides the first evidence of adult blacktip sharks (Carcharhinus limbatus) using shallow waters as a refuge from the great hammerhead shark, (Sphyrna mokarran)– proving you “can’t touch this.”

Several juvenile shark species use shallow water nursery sites where the young can grow with a reduced risk of predation. However, prior to a study by Florida Atlantic University, no documentation was available to show that large adult sharks also swim in shallower waters to avoid predation.

The use of unmanned aerial vehicles (UAVs) enabled FAU scientists to unobtrusively observe and allow natural behaviours to be documented in the wild, providing insight into seldom-seen predator–prey interactions. Results of the study are published in the Journal Fish Biology. MORE
