When we think of dolphins, the image that often comes to mind is that of the charismatic bottlenose dolphin, the star of marine parks and television shows. While bottlenose dolphins are undoubtedly remarkable creatures, the world of dolphins in the ocean is far more diverse than you might imagine. In fact, there are over 40 different species of dolphins, each with its unique characteristics and adaptations. In this blog post, we’ll take a deep dive into the fascinating world of oceanic dolphins, exploring the various species that inhabit our seas.

These intelligent dolphins are known for their striking black and white coloration, making them easily recognizable.
