Whitetip reef sharks (Triaenodon obesus) can easily be identified by their white tipped fins, oval eyes with vertical pupils as well as their tubular skin flaps. Since it is a small shark they only grow to 1.6m. Due to the fact that they have the ability to pump water over their gills which allows them to lay still on the bottom, they are quite unique amongst the requiem sharks which need to constantly swim in order to breathe.
They tend to stay in the sam reef area for month or even years and are most commonly found at depth of 8-40m. They are found all across the Indo-Pacific region and are preferably close to coral reefs.
The scenery of having them swimming around you is daily happening everywhere in the Maldives. This babies are completely harmless and will flee if you come to close, since they are more scared of you, than we are of them. I myself had the pleasure of observing how they are looking for their first catch, at close range. I was simply amazed when I got the chance to see them the first time! To be honest, I was kind of scared too in the beginning, however I am now able to say that they just extremely cute and its amusing to watch them. I still remember quite accurately a very funny situation of walking along the beach with my parents when we suddenly noticed a huge riot right next to us. The cause for this was really exciting to watch: about 4-5 blacktip baby reef sharks were trying to catch some fish by splitting up the swarm in order to close in on the now small groups.
This link to a video shows a similar situation: http://www.wimp.com/fishshoal/
Just as shown in the video "A lazy bystander tries to get in on the results".
Although it was really hard to capture this situation in a good way, I'm hoping that I am able to give you an idea of what was happening, through this picture.
