1. Sharks love the color red. 2. Sharks are said to be attracted to dogs 3. It’s a mistake to bump into a shark with a boat – especially when following one like the above, at any speed.
BEN CROPP and I assumed it was a tiger shark by the actions it displayed.
Could it have been a cranky Lemon shark – not an uncommon species at Batt Reef, and far out-numbered by the Tigers?
John D. Stevens (CSIRO) when asked for a shark ID, replied (in part): “It’s not a tiger shark, species unidentifiable”.
The confusion came after we saw numerous tiger sharks on the reef shallows earlier the same morning, attracted by – possibly – a harpooned dugong, sea turtle, or stingray – something large enough when injured to provided a stimulus attraction.
These were big sharks, 2.5 meters and upwards, with a single four meter monster seen the next day.
This seemed unusual for so many in a small area.
Batt Reef is a large and mostly sandy and shallow running some ten nautical miles in length, located off Port Douglas, Queensland. It is not a destination for tourist visitors. Quite a private place.

(Above illustration of shark teeth).From the 1950s when Grey Nurse sharks were still considered “Man Eaters”. That belief changed when the first underwater cinematographers began filming them in 1961. It took a few years for the new information to circulate in the pre-digital era.
When did white sharks begin jumping into the air after prey? It’s a recent occurrence – according to experts.
