Solo dolphins are a rare phenomenon and give us incredible insights into this species. Sadly, the more friendly the dolphin the less wary they become of us, boats and other potential hazards.
Most solo dolphins have a fascination with propellers and over the years many have been injured or killed by boats. In 2006 a female solitary dolphin was hit by a boat and later died of septicaemia. In a similar incident here in New Zealand, a solo dolphin named Scar was reversed over by a boat and subsequently euthanized as a result of his injuries.
Not everyone appreciates the presence of solo dolphins. In 1983 an angry Costa Rican fisherman killed a solo dolphin that got caught in his net. In New Zealand controversy still surrounds the death of Opo the dolphin. Many suspect foul play.
Just as people pose a risk to solo dolphins, so too is the opposite true. In the past people have been bumped, rammed, head butted, bitten, held underwater, landed on and pushed out to sea. They've walked away from their close encounter with cracked ribs, internal injuries and painful bruises. One person has even died.
If you're lucky enough to spend time with a solo dolphin please follow some simple rules:
- Don't over-crowd them, surround them or block their escape route
- Give them space. Feeding and resting times are crucial. If you disturb them during these times their health will deteriorate and they be more prone to disease
- Don't attempt to ride or be towed by them, or pull on their flippers or fin. These can be easily dislocated
- Don't encourage them to play with toys. These could damage, their skin, eyes and teeth and later by confused with objects like fishing net buoys
- Don't feed them. You could make them unwell and reduce their natural ability to hunt
- If you're in a boat and they're close by, turn off the engine and remove any nets or fishing gear from the water. Alternatively, move your boat at slow to no-wake speed and keep a straight path to avoid running over him. Keep a distance of 50 metres if you can and only approach them from the side of behind. Don't circle the, surround them or obstruct their path
