An esoteric question....

Does anyone know the scientific name of the structures on the tongues of
Puffins (and I assume other alcids?) that enable them to hold several fish in
their mouths, dive for more fish, and then fly off with the fish to their
burrows to feed their young without losing any of the fish? An answer would
be most appreciated. I have exhausted all of my "book" sources. Thanks in
advance.
