- The hydrodynamics of dolphin draftingDaniel Weihs
Faculty of Aerospace Engineering, Technion, Israel Institute of Technology, Haifa 32000, Israel
J Biol 3:8. 2004..A study of the hydrodynamics of drafting, initiated in the hope of understanding the mechanisms causing the separation of mothers and calves during fishing-related activities, is reported here...
- How do cormorants counter buoyancy during submerged swimming?Gal Ribak
Faculty of Biology, Technion Israel Institute of Technology, Haifa 32000, Israel
J Exp Biol 207:2101-14. 2004..The added cost of the drag resulting from this tilting behavior may be reduced by the fact that the birds use a burst-and-glide pattern while swimming...
- Submerged swimming of the great cormorant Phalacrocorax carbo sinensis is a variant of the burst-and-glide gaitGal Ribak
Department of Biology, Technion Israel Institute of Technology, Haifa 32000, Israel
J Exp Biol 208:3835-49. 2005..5 m s(-1)), but that as the birds dive deeper (>1 m where buoyancy is reduced), the burst-and-glide gait may become beneficial even at lower speeds...
- Consequences of buoyancy to the maneuvering capabilities of a foot-propelled aquatic predator, the great cormorant (Phalcrocorax carbo sinensis)Gal Ribak
Department of Biology, Technion, Haifa 32000, Israel
J Exp Biol 211:3009-19. 2008..The neck produced only a small portion (10%) of the normal vertical forces but its length may allow prey capture at the end of pursuit, within the minimum turning radius...
- Hydrodynamic stability of swimming in ostraciid fishes: role of the carapace in the smooth trunkfish Lactophrys triqueter (Teleostei: Ostraciidae)Ian K Bartol
Department of Organismic Biology, Ecology, and Evolution, University of California, Los Angeles, CA 91606, USA
J Exp Biol 206:725-44. 2003..All important morphological features of the carapace contribute to producing the hydrodynamic stability of swimming trajectories in this species...
- Body-induced vortical flows: a common mechanism for self-corrective trimming control in boxfishesIan K Bartol
Department of Biological Sciences, Old Dominion University, Norfolk, VA 23529 0266, USA
J Exp Biol 208:327-44. 2005..These data together with previous work on smooth trunkfish indicate that body-induced vortical flows are a common mechanism that is probably significant for trim control in all species of tropical boxfishes...
- Dynamics of the aerial maneuvers of spinner dolphinsFrank E Fish
Department of Biology, West Chester University, West Chester, PA 19383, USA
J Exp Biol 209:590-8. 2006..The model indicates that the high rotation rates and orientation of the dolphin's body during re-entry into the water could produce enough force to hydrodynamically dislodge unwanted remoras...

Department of Marine Biology, Texas A and M University, Galveston, TX 77551, USA
Philos Trans R Soc Lond B Biol Sci 362:2141-50. 2007..This type of data will require animal-borne instruments that can record the behaviour, three-dimensional movements and locomotory performance of free-ranging animals at depth...
