Cuvier's beaked whale holds the records for both the deepest and the longest dives ever documented for any mammal; [24] in 2014, scientists reported that Cuvier's beaked whale, off the coast of California, dove to 9,816 ft (2,992 m) below the ocean's surface, becoming the deepest documented dive for any mammal.
A San Diego-based ecotour operator has captured stunning aerial footage, perhaps first of its kind, showing Cuvier’s beaked whales swimming along the surface. Rare footage shows elusive ...
The Cuvier's beaked whale, or Ziphius ... It is the deepest and longest-diving mammal, with a record depth of 2,992 m [45] and an apnea time of 3 h 42. [46]
To understand the hunting and foraging behavior of beaked whales, researchers used sound and orientation recording devices on two species: Cuvier's beaked whale (Ziphius cavirostris) and Blainville's beaked whale (Mesoplodon densirostris). These whales hunt by echolocation in deep water (where the majority of their prey is located) between ...

No data show a beaked whale making an uncontrolled ascent, or failing to do successive shallow dives. [citation needed] This behavior suggests that the Cuvier's are in a vulnerable state after a deep dive – presumably on the verge of decompression sickness – and require time and perhaps the shallower dives to recover.
Johnson et al., (2004) used acoustic recording tags to record echolocation clicks produced by Cuvier's beaked whale (Ziphius cavirostris) and Blainville's beaked whales (Mesoplodon densirostris) during dives of up to 1270 m depth, indicating that they use a series of regular clicks with occasional fast buzzing sequences during deep dives. It ...
Time intervals between surfacing can vary depending on the species, surfacing style or the purpose of the dive; some species have been known to dive for up to 85 minutes at a time when hunting, [46] and dives in excess of three hours have been observed in Cuvier's beaked whale under extreme circumstances.
