Figure 1.— Drawings (not to scale) showing the longitudinal body form of the six species of sharks for which 

 swimming kinematic data were obtained. The symbols are used through most of the following figures. 



Sphyrna tiburo (L = 0.93+0.09 m; N = 5); and 

 leopard shark, Triakis semifasciata (L = 0.98+ 

 0.11 m; N = 5). The three smaller species were 

 part of a second public display in an outside pool 

 at Sea World. This pool was approximately oval 

 in shape, 9 m long, 5.5 m wide, and 0.3 m deep. 

 Small individual sharks were also observed in a 

 small rectangular tank, 2.5 m long, 1.2 m wide, 

 and 0.3 m deep. This tank had a transparent bot- 

 tom. The water temperature in all three facilities 



was the same and constant at 24.5°C. Thomson 

 and Simanek ( 1977) have shown that most sharks 

 fall into one of four functional-morphology 

 groups. Group 1 includes sharks with stream- 

 lined, fusiform, deep bodies; a narrow caudal 

 peduncle with lateral flukes (streamlining); and 

 a high aspect ratio tail. This group is represented 

 by large pelagic species, such as Lamna which 

 were unavailable for study. Group 2 is similar to 

 group 1, but lacking the deep body and stream-
