shark identified. Following each Figure is a detailed 

 description of its appearance, breeding and feeding 

 habits, migratory movements, locality and depth fre- 

 quented, size and other characteristics, all of which will 

 help you to locate the shark again if you wish. 



Key I to the Common Eulamias — Figures 22 through 29 



Many of the Eulamias resemble one another so closely 

 that few fishermen distinguish between them except 

 perhaps for one or two species that may be caught the 

 most often in any particular locality. Most of them lack 

 common names. At present only about eight of the fif- 

 teen species which are known to occur within the Carib- 

 bean area are numerous enough or large enough to be of 

 interest to fishermen. 



All Eulamias have the following features: 



An anal fin 



Five gill openings 



An ordinary shaped head 



No spiracles 



No furrow on the lower jaw and only a very short 



one on the upper 

 No ridges lengthwise on the caudal peduncle 

 Mid-point of the base of the first dorsal fin is 



nearer to the center of the pectoral fins than 



to the origin of pelvic fins 

 The cusps of the upper teeth are regularly serrate 



(or saw-edged) 

 The cusps of the lower teeth are serrate or smooth 



Eulamias are distinguished from one another as fol- 

 lows: 



A. Eulamias which have a distinct ridge along the 

 middle of the back between the first and second 

 dorsal fins and which also have (1) or (2) :
