Abstract
Studying the behaviour of the White Shark is a recent and big challenge. Optimising the photoidentification of White Shark dorsal fins is a basic goal, in order to compare behavioural information in both immature and mature specimens and between females and males. During a 6 years research, from 2009 to 2014, in South Africa, we observed 296 sharks and 8 specimens were resighted several times. Data about sex, sizes, environmental conditions and behaviours were collected. This is the first step to develop a more complex database in which all the observed behaviors for each shark in different environmental conditions will be included.
