how deep can sperm whales dive

Sperm whales are thought to dive regularly to around 1,000 meters (about 3,300 feet) and can reach at least about 2,000–2,250 meters (6,600–7,400 feet) in especially deep dives.

Quick Scoop

• Typical dive depth: around 600–1,000 meters where they hunt deep‑sea squid.

• Deep “recorded” dives: about 2,000–2,250 meters (roughly 2 km below the surface).

• Dive duration: often 45–60 minutes; some measured dives last over 1 hour.

• Why they go so deep: to reach dense layers of squid and other deep‑sea prey that stay in near‑darkness.

How this compares to other deep divers

• Sperm whales are among the deepest‑diving mammals, but a few beaked whales have recorded even longer and deeper dives.

• Still, for a 15–20 meter animal with the largest brain on Earth, their ability to routinely work at 1 km depth is extraordinary.

In simple terms, when you ask “how deep can sperm whales dive,” the best current evidence points to routine dives near 1 km and exceptional dives a bit beyond 2 km down.
