The process continued over time, and a very derived form of hyperphalangy, with six or more phalanges per digit, evolved convergently in rorqual whales and oceanic dolphins, and was likely associated with another wave of signaling within the interdigital tissues. Five digits help support a broad flipper (e.g., right whales), while four digits closely appressed are seen in narrow, elongated flippers (e.g., humpback whales). small ears and long necks Humpback whales use their flippers to create a barrier that traps gathered prey, which they can then usher towards their mouths by swatting the water.
