lemon shark
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.

At first Ben and I thought it was a tiger shark. Now I am not so sure after receiving an email reply from John D. Stevens of Australia’s CSIRO.  Maybe it was a lemon shark after all?

John D. Stevens says: “It’s not a tiger shark, species unidentifiable”.

The confusion was came after we saw numerous tiger sharks on the reef shallows that same morning, attracted by possibly a harpooned dugong or 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.

Unusual for so many in a tiny area without something having brought them in.

Batt Reef is a big sandy and shallow reef running some ten nautical miles in length, located off Port Douglas, Queensland.

(It’s where the TV celebrity Steve Irwin was fatally spiked in the chest by a large stingray a few months after our episode also at Batt Reef).

  1. I’ve dived in the Coral Sea at a place called Hungry Jack’s reef. It’s a turtle breeding ground and the local dive operator took people snorkeling there. That is until a huge Tiger shark attacked a turtle on the surface in full sight of the snorkelers. There’s a staggering number of sharks there. In New Zealand we have Mako’s that are known to attack the prop on speed boats while moving at speed.
