Relative pleopod length as an indicator of size at sexual maturity in slipper (Scyllarides squammosus) and spiny Hawaiian (Palinurus marginatus) lobsters.
Upon extrusion, eggs were removed from the pleopods by grasping the top of the pleopod with forceps and scraping the eggs from the pleopod.
During the first two stages pleopod (legs) has yet been formed.
Remarks: The secondary male differs substantially from the primary male, not just in respect of the typical characters of size and cheliped development, but also as regards the antennule structure, and pleopod setal number (higher in secondary male).
The central projection diverges from the mesial process and the central projection length to total length of pleopod (mean = 44.
Appendage-to-body size proportions, such as the pleopod length metric, hold great promise, particularly for species of slipper lobsters like S.
Twelve larval stages have been previously reported and there were four main features associated with the classification of the different stages: eyestalks, pleopod formation, telson/uropod development, and number of rostrum teeth.
The length and height of the propodus of the largest cheliped, the length of the merus of the second walking leg, and the length of the primary pleopod of each male crab in Cockburn Sound and Shark Bay were measured to the nearest 0.
The carapace width (CW) and carapace length (CL), the abdominal width (AW; measured at the junction between the fourth and fifth abdominal segment), the length of the propodus of the major cheliped (ChL), the length of the second right pleopod (2PL), and the length of the merus of the second and third left pereopod (first [1L] and second [2L] walking leg, respectively) of each crab were measured using an SPI 2000 series dial caliper (precision, 0.
Eggs were then carefully teased off pleopod setae with jeweler's forceps and stored after being wrapped in cool, damp paper towels to minimize evaporative weight loss.
