- Both Sanganeb and Sha’ab Rumi are home to large numbers of cetaceans, and especially resident populations of dolphins.
- At least three species of dolphin (bottlenose dolphin, the common dolphin and the spinner dolphin) can be found in SMNP as well as Sha’ab Rumi. Very little data exists on the identity and distribution of cetaceans in the Sudanese Red Sea in general.
- A resident pod of 8-10 bottlenose dolphins (Tursiops truncatus) are frequently observed around Sanganeb jetty, and use the SMNP lagoon as a birthing site. Individuals from this pod will approach small boats and bow-ride, which adds greatly to the potential for dolphin watching tours.
- Observations suggest that humpback whales (Megaptera novaeangliae) and pilot whales or false killer whales occur around SMNP during winter months.
