WHALES & DOLPHINS
MONITORING OF WHALES AND DOLPHINS
Our marine biologists and guides collect observational data about all whales & dolphins spotted whilst onboard the vessels of our partner company, Dyer Island Cruises. All sightings are mapped and this creates a knowledge foundation that is used for various studies. On each trip, we take readings of water temperature, pressure and oxygen levels.
The collection of this observational & environmental data is critical to the understanding of the cetaceans frequenting our area and the studies of various biologists.
WHALES
IUCN Classification – LEAST CONCERN
EUBALAENA AUSTRALIS
Southern right Whale
They frequent our area between June to November / December and are here to mate and calve. The DICT collect whale faeces for a study on feeding habits – the whales do not generally feed when here but some feeding behaviour is observed. We have supported genetic studies and collect non-invasive samples when required. Where possible we participate in acoustic research. We work co-operatively on projects with the Mammal Research Institute Whale Unit situated at the University of Pretoria and we support their annual whale aerial survey
MEGAPTERA NOVAEANGLIAE
Humpback Whale
This species migrates along our coastline throughout June to August, heading toward warner waters off Mozambique. They head back again usually around December. All sightings are logged.
