The throats of all beaked whales have a bilaterally paired set of grooves that are associated with their unique feeding mechanism, suction feeding. [9] Instead of capturing prey with their teeth, beaked whales suck it into their oral cavity. Suction is aided by the throat grooves, which stretch and expand to accommodate food.
Blainville's beaked whales do not capture prey by biting. They use suction feeding to capture prey. They create low pressure in the mouth by retracting tongue, and using throat grooves to expand throat volume. This creates a lower pressure in the mouth than the surrounding waters, allowing the whale to suck in water and whole prey. [12]
All members of the family have a series of longitudinal folds of skin running from below the mouth back to the navel (except the sei whale and common minke whale, which have shorter grooves). These furrows allow the mouth to expand immensely when feeding. [5] These "pleated throat grooves" distinguish balaenopterids from other whales. [5]
As the whales swim up to the surface to feed they can hold up to 15,000 gallons of sea water in their mouths. [citation needed] Humpback whales have 14 to 35 throat grooves that run from the top of the chin all the way down to the navel. [3] These grooves allow the mouth to expand. [3]
Perrin's beaked whale (Mesoplodon perrini) is part of the toothed whale suborder and is one of over 90 known cetaceans in existence today. [3] Beaked whales are part of the family Ziphiidae , which are the second most diverse group out of all marine mammals with over 20 species currently recognized. [ 4 ]
