travel notes

Tiger sharks are considered the second most dangerous shark to man and it is true that they are indiscriminate predators. Diving with tigers is a mesmerising experience and some reach up to 5m in length.
What can be learnt from diving with these sharks is that they are very tolerant of other predators as we often see them with 30 or more black tip sharks. Presumably this is why the tiger shark is so tolerant of divers. The tiger sharks are attracted using bait so they will stay around the divers, but they are not fed. Personally the most reliable operator in the area using this technique which enables you to dive with tiger sharks on snorkel or scuba.

Blacktip shark is a species of requiem shark, family Carcharhinidae. It is common to coastal tropical and subtropical waters around the world, including brackish habitats. Genetic analyses have revealed substantial variation within this species, with populations from the western Atlantic Ocean isolated and distinct from those in the rest of its range. The blacktip shark has a stout, fusiform body with a pointed snout, long gill slits, and no ridge between the dorsal fins. Most individuals have black tips or edges on the pectoral, dorsal, pelvic, and caudal fins. It attains a maximum length of 2.8 m (9.0 ft).
