In many beaked whale species, erupted teeth are used primarily for male competition rather than feeding.
Unlike many toothed whales, adult male Cuvier’s beaked whales possess only a pair of erupted teeth, and females often show none externally. Feeding relies primarily on rapid suction rather than biting. The elongated rostrum and reduced dentition support this strategy. By retracting the tongue and expanding the throat region, the whale creates negative pressure that draws squid and fish inward. Anatomical studies describe reinforced hyoid bones adapted for powerful suction. This feeding mechanism is particularly effective in deep-sea environments where prey may be soft-bodied. Suction feeding reduces the need for grasping in darkness. Morphology aligns with ecological niche. Design reflects depth specialization.

Feeding adaptations influence vulnerability to prey shifts caused by climate variability. If squid distribution changes, suction specialists may face foraging challenges. Comparative anatomy studies across cetaceans inform understanding of evolutionary trade-offs. Reduced dentition also limits defensive capability against predators. Morphological specialization narrows ecological flexibility. Research into feeding mechanics supports broader ecosystem modeling. Form shapes opportunity.
For marine anatomists, the near absence of functional teeth contrasts with the whale’s extreme diving ability. The irony is structural: one of the deepest-diving mammals depends on a feeding method that avoids biting. Cuvier’s beaked whales succeed through vacuum rather than force. Precision replaces aggression. Efficiency governs capture. Depth favors adaptation.
