The used markings called spaguetti since they look like a noodle. Are placed in sharks and other marine animals in order to learn about their movements. Each animal that is marked with a spaguetti has a known specie, size,gender and location. In this way when recaptured it is possible to know how far it has moved and in some occasions it is also possible to find out how much it grew.

You or someone in your staff may find one of the marked specimens that are swimming around our oceans and the oceans worldwide.
