Density curves for different fishing areas for (A) males and (B) females and medians, quartiles (Ql=lower 
quartile, cuts off lowest 25% of data and Q3=upper quartile, cuts off highest 75% of data), and ranges for 
(C) males and (D) females of the total lengths of the hooded slipper lobster (Scyllarides deceptor) caught 
by pot-and-trap and double-trawler fleets off southeastern Brazil from May 2006 through April 2007. 
The different shadings for graphics located on the right side: from the darker to lighter (top to bottom) 
indicate areas in numerical order (1, 2 (dashed lines in white], 3, 4, and 5, respectively). Arrows mark 
the capture of juvenile and adult females. 
in agreement with the results of Oliveira et al. (2008), 
who observed females that were 36.0 cm TL and males 
that were 31.0 cm TL. This characteristic is common in 
the Scyllaridae, but the opposite phenomenon occurs in 
the Palinuridae and Nephropidae (Spanier and Lavalli, 
2007). In our study, the maximum sizes obtained were 
larger than the 32 cm TL reported by Holthuis (1991) 
and Spanier and Lavalli (2007). However, the hooded 
slipper lobster measured in our study were captured 
farther southeast in Brazil than were the hooded slip- 
per lobster observed by Holthuis (1991) and Spanier 
and Lavalli (2007), and the lobster in our study were 
caught at maximum sizes that were similar to those of 
lobster found south of Brazil by Oliveira et al. (2008). 
Those authors also identified 2 migration patterns 
for the hooded slipper lobster. One of them occurs daily 
and relates to foraging, and the other is seasonal for 
the hatching of larvae in shallower water. This latter 
migration pattern was confirmed in our study because 
only 4.5% of females were recorded at depths >100 m 
(area 4), and the remaining females were captured in 
shallow areas (mean depth <100 m): 27.3%, 63.6%, and 
4.5% in areas 1, 2, and 3, respectively. According to 
information from fishermen in both fleets, each fish- 
ing area has the following typical substrate proper- 
ties (granulometric predominance): area l=sand, mud, 
and gravel (calcareous algae); area 2=mud and sand; 
area 3=sand and gravel; area 4=mud and sand; and
