In addition, other species of Scyllaridae have commercial value, including 4 species of the genus Ibacus, the velvet fan lobster (7.
The reproductive biology of members of the Scyllaridae (Lavalli and Spanier, 2007) has been studied for the genera Thenus (Kagwade and Kabli, 1996; Courtney et al.
Species of Scyllaridae also are targeted by other fisheries (e.
Brazil currently has no fishery management legislation that regulates the extraction of slipper lobsters in its waters, and data on the reproductive biology of these species of Scyllaridae would provide important life-cycle information that could be used for decision-making.
This reproductive strategy is evident in Scyllaridae, as seen in the relationship between the mean sizes of lobster species and their gonadal maturation, fecundity, and egg diameter.
This hypothesis would be supported by the lack of giant neurons in spiny lobsters, because Palinuridae is the sister group to Scyllaridae.
Given that the giant escape circuit is absent in representative species in both Palinuridae (this study) and Scyllaridae (Faulkes, 2004), it is more parsimonious to assume that the giant escape circuit was lost once in the palinuran infraorders rather than repeatedly throughout the group.
