Moreover, surprisingly, accompanying the processes of developing upwardly oriented nostrils there are profound changes within the braincase.”

   Are fin whales toothed or baleen whales?

   • Fin whales are from a group called the baleen whales, named for their distinct feeding apparatus. “I’m struck by two interesting discoveries that emerged from this work,” said Roth. “Although they both develop blowholes, there are key differences between a baleen and a toothed whale in how they reorient their nasal passages during development.

   How does a dolphin's nasal passage shift during embryonic development?

   • New research is shedding light on how the nasal passage of dolphins and whales shifts during embryonic development from emerging at the tip of the snout to emerging at the top of the head as a blowhole. The findings are an integrative model for this developmental transition for cetaceans.

   How did a cetacean blowhole evolve?

   • As cetaceans evolved, the blowhole gradually migrated from the tip of the snout to the back of the snout, and then gradually up to the top of the skull. In addition, the two species represent different branches of the cetacean family tree that diverged more than 30 million years ago.

   Why do cetaceans have a blubber nose?

   • They have blubber to insulate and fins to propel and steer. Today’s cetaceans also sport a unique type of nasal passage: It rises at an angle relative to the roof of the mouth — or palate — and exits at the top of the head as a blowhole. This is an apt adaptation for an air-breathing animal at home in the water.

   How did the blowhole evolve?

   • These creatures began to evolve from a four-legged, land-dwelling mammalian ancestor, which had a nasal passage parallel to the palate, more than 50 million years ago. As cetaceans evolved, the blowhole gradually migrated from the tip of the snout to the back of the snout, and then gradually up to the top of the skull.

   Jul 19, 2021 · In this study, we have deconstructed blowhole development into the following components: rostral growth and elongation; head reorientation relative to the body axis; and nasal passage reorientation relative to the palate (or rostrum), the basicranium, and the foramen magnum.

   Unlike other mammals, cetaceans (e.g., whales, dolphins, and porpoises) have evolved a "blowhole": posteriorly repositioned nares that open dorsad. Accompanying the evolution of the blowhole, the nasal passage has rotated dorsally.
