Figure 4. — Stage II zoea of Eualus suckleyt: A, cara- 

 pace, right side; B, antenna, ventral; C, telson, ventral. 



mm 



Telson with 8 + 8 plumose setae; setae noticeably 

 shorter than in Stage I (Figure 4C). Uropods 

 enclosed. 



Etialus fabricii — Stage I and II Zoeae 



Stage I and II Eualus fabricii are similar 

 morphologically to Stage I and II E. suckleyi; 

 however, they can be distinguished. Stage I and II 

 of £. fabricii are slightly larger than Stage I and II 

 E. suckleyi, and armature of the fourth and fifth 

 abdominal somites and numbers of spines and 

 setae differ between the two species. 



Stage I Zoeae 



Mean total length of Stage I, 3.7 mm (range 

 3.5-3.8 mm, 10 specimens). Carapace and rostrum 

 similar to those of Stage I E. suckleyi, except 

 no spines adjacent to pterygostomian spine on 

 anterior margin of carapace. 



Antennule. — Minute projection at base of conical 

 projection of antennule (observable only under 

 high [400 X] magnification). 



Antenna. — Same as antenna of Stage II E. 

 suckleyi (Figure 4B), except flagellum about 1.5 

 times length of scale. 



Mandibles. — Same as Stage I E. suckleyi. 



Maxillule. — Seven spines on coxopodite; nine 

 spines on basipodite. 



Maxilla.— Three (sometimes 4) setae on distal 

 lobe of coxopodite; 11 setae on proximal lobe. Six 

 setae on each lobe of basipodite. 



Maxi'// jpeds. — Similar to Stage I E. suckleyi 

 except no epipodite on first maxilliped. 



Pereopods. — Same as Stage II E. suckleyi.
