DOI: 10.1002/jmor.20992
Abstract: Hydrofoil‐shaped limbs (flipper‐hydrofoils) have evolved independently several times in secondarily marine tetrapods and generally fall into two functional categories: (1) those that produce the majority of thrust during locomotion (propulsive flipper‐hydrofoils); (2) those used primarily… read more here.
