It is impossible to say exactly how many dolphins exist worldwide. Dolphins inhabit all the world’s oceans, are constantly on the move, and some species live in deep waters that are difficult to study. Populations also fluctuate based on prey availability, pollution, and fishing practices.
Scientists have estimated that there are around 100 million dolphins worldwide, though this is only an estimate and the real number could be higher or lower.
Even with these numbers, many dolphin species face threats such as habitat loss, entanglement in fishing gear, and pollution.
