These species may never venture towards the oceans. Scientists speculate this due to either a strong attachment to the niche, or initial habitat, or simply because they know that life within the seas are slightly more perilous than those in the river.

Do bottlenose dolphins live in warmer water?

for example, The bottlenose dolphin prefers to live in warmer waters, while most other dolphins prefer the cooler waters away from the equator. Another example, Dolphins that love to feed on planktons are often attracted to the coastal areas.

A population of Indo-Pacific humpback dolphins live …

What are the animals that live in colder waters?

Several other species may also be encountered in colder waters, such as white-beaked dolphins (arctic) and hourglass dolphins (antarctic), but most dolphins prefer tropical and temperate waters as they are warm-blooded mammals and so it is easier for them to regulate their body temperature in these environments. Spinner dolphins and spotted dolphins are two such species that may be encountered in warm waters.
