✓Accepted Answer

The Sri Lankan subspecies of the Asian Elephant (Elephas maximus maximus) is unique because tusks are genetically rare: fewer than 7% of adult males grow visible ivory tusks (compared to nearly 100% in African elephants), with the majority being "makhnas" (tuskless males). In Udawalawe National Park, prominent individual tuskers (such as the famous "Samanala" or "Gemunu") command high status during breeding seasons. Tuskers use their ivory weapons to assert dominance during intense sparring matches with rival bulls, securing breeding access to nursery herds congregating along the reservoir grasslands.

Historical ivory hunting during the British colonial era heavily targeted tuskers, exerting strong evolutionary pressure favoring tuskless genetics in surviving populations.

Spotting a wild tusker in Udawalawe is a prized highlight for afternoon safari jeeps operating around the central reservoir flats.

Safari drivers communicate tusker locations via radio channels; maintain a respectful 25-meter buffer distance when encountering dominant bulls.
