In most cases, humpback whales are not considered to be a threat to humans. They are typically curious and playful, and they may approach boats or swimmers out of curiosity. However, it is important to remember that humpback whales are large animals and they can be unpredictable. If a humpback whale feels threatened, it may slap its tail or flukes on the water, which can cause serious injuries to anyone in the area.
In some cases, humpback whales have been known to come too close to humans and cause damage to property. For example, in 2015, a humpback whale breached the water near a boat in Hawaii and landed on the deck, causing extensive damage to the vessel.
It is important to be aware of the potential risks associated with humpback whales and to take steps to avoid getting too close to them. If you are in an area where humpback whales are known to frequent, it is important to stay at a safe distance and to avoid making any sudden movements that could startle the whales.
