Pygmy Sperm Whale Trivia Questions

Female pygmy sperm whales can reach lengths of up to 13.9 feet (4.25 m), so they routinely exceed 10 feet. Males max out around 11 feet, making the claim false.

They have a sac in their intestine that holds up to 12 liters of dark fluid, which they release to confuse attackers.

Their dorsal fin is small, falcate, and set far back on the body—not tall or shark-like at all.

They produce only short, simple clicks for echolocation—no complex songs like humpbacks or blue whales.

They are typically solitary or found in small groups of 3–5; large pods are not their social style.

Pygmy sperm whales have 12–16 tiny teeth only on the lower jaw, and sperm whales also have teeth only on the lower jaw (with sockets but no teeth in the upper jaw). Thus, the similarity is accurate.

Unlike most whales, the pygmy sperm whale's blowhole is asymmetrical and positioned toward the left side of the head.

Logging is a resting behavior in many whales, not a defensive response. When threatened, pygmy sperm whales typically eject a dark, ink-like fluid to confuse predators.
