• Shark cage diving in Gansbaai, South Africa with Marine Dynamics. Experience the exceptional and come face to face with a great white shark! 

  • The exact world record white shark is a contested issue, but chances are it is between 6-7m. In Gansbaai, the largest white shark ever caught was at Danger Point and measured up to 5.9m.

  • If you see a white shark in the water don’t panic. Chances are high that the shark has already detected you and isn’t interested. White shark attacks are normally associated with poor visibility, so avoid murky conditions.

  • White sharks have a unique system called a “counter current heat exchange”, which keeps their body  tempreture +/- 7C above the surrounding water temperature. 

  • All sharks have an incredibly unique system on the tip of their nose called the “ampillae of Lorenzini”. These are small pores filled with a gel that transmits the electrical currents in the water to the shark’s brain so that it can assess its environment.

  • White sharks give birth to live young (not eggs), and they give birth to 6-8 pups at one time. Pups are usually between 1.0-1.5m in length and are born with teeth.

  • Body language has been a well documented form of shark communication and has identified body arching, jaw gaping, and other postures as specific social tactics.

Fishing Line Bin Project

In 2010, recognising the ever-increasing hazards to animals and humans of discarded fishing line the Dyer Island Conservation Trust (DICT) began a Fishing Line Bin Project, a special recovery and recycling project with the local Overstrand Municipality. By means of this project the Trust increases public awareness of the negative impacts of fishing line debris and encourages correct disposal by a network of unique fishing line bins strategically placed along the coastline. The Trust, International Marine Volunteers and a dedicated group of young learners from the Trust’s Environmental Education Programme known as DEEP, helps ensure these bins are emptied, the fishing line cleaned and options for recycling are being looked at.

Today the program is nationwide and more than 350 collection bins have been installed along the coast.

In Gansbaai alone >50kg of discarded fishing line have been collected.

Marine Disentanglement and rescue

Working close with the local community, such as Cape Nature, Department of Environmental Affairs and fisherman, the Trust provides the emergency response to disentangle whales and other animals trapped in fishing lines. We attend and record all strandings of animals in the area and take samples for analysis where necessary.

Beach Clean- Ups

The DICT together with the Overstrand Municipality, local organisations and schools, the Trust organises teams to collect, and where possible recycle waste that washes up on the local beaches.

The DICT is committed to working in partnership with our community to involve them in their work to protect our unique marine eco-systems for future generations of South Africa!
