Read MoreDespite its docile nature during the day this nocturnal shark can become aggressive when hunting at night, thrashing through coral reefs looking for potential prey. The whitetip reef shark usually hunts alone, but is non-territorial and will occasionally work in cooperation with others in the pursuit of prey . Feeding primarily on bottom-dwelling octopus, lobsters, crabs and bony fish, it often chases its prey into a crevice before jamming its body in after it, sealing the exit . The extremely posterior location of the first dorsal fin compared to those of other sharks is an adaptation to this feeding habit, which allows them to get their heads and mouths much further into the gaps and holes in the coral . The whitetip reef shark's mating season varies with location . Reproduction is viviparous and after a gestation period of around a year the female will give birth to one to five live pups, which are completely independent at birth . Both sexes reach sexual maturity at approximately 5 years old, and it is estimated that this species can live to an age of 25 years .
Almost flat calm seas. Easy access to dive site from the cul de sac. High tide was at 19:00 approx. Visability was down to about 3-4 m with quite a lot of sediment in the water. Still, it was an excellent dive and the sunset on surfacing was amazing. Few fish about, mostly starfish and crab.
Este mergulho serviu para testar a utilização de fatos secos, uma vez que nunca tinha experimentado.
A experiência não foi muito agradável uma vez que o fato me estava muito apertado no pescoço e senti algumas dificuldades ao respirar e ao mexer-me.
