ZOEA I 



(Figure 7) 



Antennule unsegmented; five to six terminal 

 processes including four aesthetascs and one or 

 two setae. 



Antenna biramous, with endopodite and pro- 

 topodite fused; endopodite with terminal point, 

 subterminal tubercle and fine seta between; ex- 

 opodite approximately I14 times as long as en- 

 dopodite with one, two, or three prominent distal 

 spines and one long seta proximal to spines. 



Mandibles strongly sclerotized asymmetrical 

 appendages, heavily armed with teeth and tu- 

 bercles on leading edges. 



Maxilla I with unsegmented endopodite bear- 

 ing three to six terminal and subterminal setae 

 and a number of fine hairs along anterior mar- 

 gin; basal endite with 9 or 10 setae; coxalendite 

 with 8 to 10 setae. 



Maxilla II with unsegmented endopodite 

 which bears 7 to 10 setae, grouped 2-3, 2, 3-4 

 progressing distally. Basal endite bilobed: dis- 

 tal lobe with 8 to 10 setae ; proximal lobe with 

 6 to 10 setae. Coxal endite bilobed: distal lobe 

 with four to eight setae; proximal lobe with 7 

 to 11 setae. Scaphognathite with six to eight 

 long plumose marginal setae and one strong 

 apical seta. Numerous fine hairs occur on 

 scaphognathite margin between plumose setae 

 and elsewhere on appendage as figured. 



Maxilliped I biramous. Coxopodite with two 

 or rarely three distal setae. Basipodite with 10 

 setae usually grouped 2, 2, 3, 3 proximal to distal. 

 Endopodite four-segmented: segment 1 with 

 two or three distal setae, inner margin; seg- 

 ment 2 with three distal setae, inner margin; 

 segment 3 with usually two medial and three 

 or rarely four distal setae, inner margin; seg- 

 ment 4 with five to seven terminal setae and one 

 proximal seta, outer margin; segments 2 and 3 

 also bear groups of fine hairs as figured. Ex- 

 opodite two-segmented, the distal segment bear- 

 ing four terminal natatory setae. 



Maxilliped II biramous. Coxopodite lacking 

 setae. Basipodite with usually two but some- 

 times one distal seta and one medial seta, inner 

 margin. Endopodite four-segmented: segment 

 1 with usually two but sometimes with one distal 



seta, inner margin; segment 2 usually with two 

 but rarely one or three distal setae, inner margin; 

 segment 3 with one medial seta or occasionally 

 two setae, and usually two, but sometimes three 

 distal setae, inner margin; segment 4 with three 

 to five terminal setae and one proximal seta, 

 outer margin; segments 2 and 3 also bear groups 

 of fine hairs as figured. Exopodite two-segment- 

 ed, the distal segment bearing four terminal 

 natatory setae. 



Maxilliped III a small bilobed bud which 

 grows throughout stage. 



Pereiopod buds simple, five pairs in number, 

 growing throughout the duration of the stage. 



Abdominal segments five in number; seg- 

 ments 3, 4, and 5 having serrations on dorsal 

 posterior margins; segments 4 and 5 with strong 

 ventrolateral spines on posterior margin. 



Telson with seven symmetrically placed pairs 

 of processes, with seventh pair on central prom- 

 inence. Outer margin to center line: one heavy 

 lateral spine fused with telson, one short fine 

 seta, and five long plumose articulating setae, 

 all armed distally with a series of short, curved 

 fixed spines (Figure ID) ; numerous fine hairs 

 on telson margin (not figured) between all major 

 plumose setae; anal spine present. 



Chromatophore pattern as noted for the pre- 

 zoea; extended rostrum with one terminal and 

 one subterminal band of red color; posterior 

 spines each with one terminal red band. Cara- 

 pace 1.31 to 1.48 mm in length. 



ZOEA II 



(Figure 8) 



Antennule biramous; exopodite with six or 

 seven terminal processes including four aesthet- 

 ascs and two or three setae followed by five tiers 

 of subterminal aesthetascs grouped 3, 4, 3, 3, 2 

 proximal to distal. 



Antenna biramous; endopodite same form as 

 in zoea I; exopodite similar to that in zoea I with 

 one to three spines, one seta distally; spines 

 somewhat less prominent than in zoea I; exopo- 

 dite approximately three-quarters length of en- 

 dopodite. 



Mandibles larger than in zoea I and with 

 prominent palp bud.
