Research on fish locomotion has expanded greatly in recent years as new approaches have
been brought to bear on a classical field of study. Detailed analyses of patterns of body and …

As a result of years of research on the comparative biomechanics and physiology of moving
through water, biologists and engineers have made considerable progress in understanding …

Inspired by the relatively simple morphological blueprint provided by batoid fish such as
stingrays and skates, we created a biohybrid system that enables an artificial animal—a …

Numerical simulations are used to investigate the hydrodynamic benefits of body–fin and fin–
fin interactions in a fish model in carangiform swimming. The geometry and kinematics of the …

Recent studies have shown that by utilizing the interactions among median fins (the dorsal,
anal, and caudal fins), fishes can achieve higher propulsion performance at the caudal fin …

We designed a robotic fish caudal fin with six individually moveable fin rays based on the tail
of the bluegill sunfish, Lepomis macrochirus. Previous fish robotic tail designs have loosely …

Fishes are found in a great variety of body forms with tail shapes that vary from forked tuna-
like tails to the square-shaped tails found in some deep-bodied species. Hydrodynamic …

Numerical studies are presented on the propulsive performance and vortex dynamics of
multiple hydrofoils pitching in an in-line configuration. The study is motivated by the quest to …

The fins of fishes are remarkable propulsive devices that appear at the origin of fishes about
500 million years ago and have been a key feature of fish evolutionary diversification. Most …

We present unifying rules governing the efficient locomotion of swimming fish and marine
mammals. Using scaling and dimensional analysis, supported by new experimental data …
