dolphins / whales

More than 30 species of the highly evolved marine mammals that we know as dolphins populate the world’s oceans – and also some rivers! In biological taxonomy, all dolphins actually belong to the suborder of toothed whales, which also includes porpoises, belugas, sperm whales, and beaked whales.

The oceanic dolphins comprise several species that are commonly called whales, with the ones most widely known being the killer whale (orca) and the pilot whale. The river dolphins belong to several different biological families; well-known species are the Ganges river dolphin and the Amazon river dolphin. While The Dolphin’s Voice aims to contribute to the protection of all cetaceans (whales, dolphins, and porpoises), our main focus are the oceanic dolphins and river dolphins.

plastic pollution

Really shocking!
This issues can not be longer ignored.

Think about using #singleuseplastics! Over 600 species are negatively impacted by marine debris. Millions of tons of plastic garbage pollute the ocean each year. Marine animals, whether small fish or large dolphins and whales, take in the microscopic particles. Hundreds of thousands of dolphins, whales, seals, sea turtles and even polar bears became victims of plastic waste, not to mention the millions of seabirds.

our latest school project

photo identification of beluga whales

Every summer when the ice has melted, hundreds of beluga whales gather in a bay in the Canadian Arctic, where warmer fresh water flows into the sea. There, they raise their young ones, go through the molting process, and mate. But is it the very same belugas that return to this bay every year? Could climate change and the associated changes in sea currents and temperatures affect their annual routine?

Scientists and photographers try to identify individual belugas by their particular characteristics and recognize them on photographs of different years. To this end, their so-called dorsal ridge can be used, a firm crest that extends along their back and often has a pattern of notches and scars. This pattern serves as a fingerprint of individual belugas. In the school project that we present here, kids can discover how to identify belugas by examining photos of belugas and trying to find matching pictures from different years.
