Vessel strikes can injure or kill sperm whales. Few vessel strikes of sperm whales have been documented, but vessel traffic worldwide is increasing, which increases the risk of collisions. Additionally, since sperm whales spend long periods (typically up to 10 minutes) “rafting” at the surface between deep dives, they are more vulnerable to vessel ...
Sperm whales can become entangled in many different types of fishing gear, including trap lines, pots, and gillnets. Once entangled, they may swim for long distances dragging attached gear, potentially resulting in fatigue, compromised feeding ability, reduced reproductive success, severe injury, or death. Sperm whales have also been documented to ...
Underwater noise pollution can interrupt the normal behavior of sperm whales, which rely on sound to communicate. As ocean noise increases from human sources, communication space decreases—the whales cannot hear each other, or discern other signals in their environment as they used to in an undisturbed ocean. Different levels of sound can disturb a...
Sperm whales can ingest marine debris, as do many marine animals. Debris in the deep scattering layer where sperm whales feed could be mistaken for prey and incidentally ingested, leading to possible injury or death.
The effects of climate and oceanographic change on sperm whales are uncertain, but both can potentially affect habitat and food availability. Whale migration, feeding, and breeding locations for sperm whales may be influenced by factors such as ocean currents and water temperature. Increases in global temperatures are expected to have profound impa...
The threat of contaminants and pollutants to sperm whales and their habitat is highly uncertain and further study is necessary to assess the effects of this threat. Little is known about the possible long-term and transgenerational effects of exposure to pollutants. Marine mammals are considered to be good indicators for concentrations of metal and...

One individual made two extremely long dives of 173 minutes and 222 minutes, which the researchers thought might be reaching the limits of the species' diving capacity. All whales rely on coming to the surface of the water to breathe oxygen - so they must hold their breath for remarkably long periods of time.
Sperm whales are usually found in deep, off-shore waters, but may be seen closer to shore, in areas where the continental shelf is small and drops quickly to depths of 310 to 920 metres (1,020 to 3,020 ft). [11] Coastal areas with significant sperm whale populations include the Azores and Dominica. [142]

Apr 15, 2013 · Sperm whales can dive over 6,500 feet, remaining under water for more than an hour. Sperm whales dive deep into the ocean for prey like giant squid, a feat people can virtually experience in an interactive in the Whales exhibition.
Sperm whales are known to dive as deep as 3,280 feet in search of squid to eat. These giant mammals must hold their breath for up to 90 minutes on such dives. These toothed whales eat...
