R., Stewart, B. S., Clapham, P. J. and Powell, J. Undertake ongoing research and monitoring to determine more about the species' life history parameters, distribution, movement patterns and population sizes. ENSO periodically fluctuates between three phases: La Niña, Neutral and El Niño. Striped Dolphin … Rapid changes in salinity during the onset of El Niño may have affected the abundance and distribution of fish species. — Maui Dolphin 39. © West Australian Newspapers Limited 2020.

The Bottlenose Dolphin lives in coastal waters and oceans. The Bottlenose Dolphin has a short rounded snout, described as bottle-shaped, a smooth rounded melon.
