On these pages the individual blacktip reefsharks have been identified. This helps to get an estimate of numbers and age, males and females and to keep track on the population of blacktip reefsharks around Phi Phi Islands.

At the moment (2017) 254 different individual sharks have been registered starting from January 1993. Of these 62 have been identified as males. 103 sharks are individuals seen more than 1 year, some of them 6-7 years in a row. Two sharks "Pen" and "Mai" have been seen from 2006 as well as 2017. There is evidens of mating in the month of July, as several of the females have fresh bite marks on their bodies. From the photos it can be seen that even deep bite marks and bruises will heal completely. Look at "Noi"

This year (2017) in July there were at least 46 different sharks. I saw up to 25 sharks at the same time and have identified 46 different individuals to PhotoID. 10 of the registered sharks were males. Very young sharks (40 cm) to adult pregnant females. 30 sharks are sharks known from previous years and 16 sharks are new ones. Again Pen and Mai from 2006 were seen. No sharks were seen with hooks this year. With the help of Shark Guardian and others we hopefully can keep the blacktips of this area from the soup bowls.

If you see sharks around Phi Phi and are lucky to get a photo please mail it  with the following information:

Place (around Phi Phi Islands):

Estimated size of the shark:

The photo should be of the RIGHT SIDE of the animal

Should the shark be observed more than one year it gets a name.

The following specimens have been recorded at Long Beach, Hin Phae and Phi Phi Leh:
