“…This pattern agrees with transport in the estuary because megalopae actively swim in the water column during flood tides at night, but are rarely collected at any time during the day (e.g. DeVries et al 1994). This pattern results from light inhibition of swimming during the day (Forward & Rittschof 1994) and an ascent in the water column in response to the salinity increase dunng rising tide at night (Tankersley et al 1995).…”

“…Thus, we did not allow larvae to behaviorally evade predators. Additionally, some species of larvae may gain a spatio-temporal refuge from predators by avoiding portions of the water column where visual predators are active, or by being released at a time of year when predators are absent (Shanks 1986, DeVries et al 1994. Our temporal abundance data, however, suggest that larvae at this temperate location are most abundant from spring to fall, the time period when potential larval predators are most abundant (Hay & Sutherland 1988).…”

Predation is bel~eved to be a major source of mortal~ty for larvae of benthlc Invertebrates, but the palatab~hty of larvae commonly found In the water column has rarely been assessed Larval palatability assays were conducted by collecting live invertebrate larvae from a temperate f~e l d slte and offerlng them to a suite of common predators (the flshes Lagodon rhomboides, Leiostomus xanthurus, and Monacanthus h~s p~d u s and the hard coral Ocul~na arbuscula) By crushing larvae that were rejected intact and re-offering them to pledators it was poss~ble to distinguish between defenses based on morpholog~cal and chemical character~stlcs of the larvae Add~tlonally, abundance data were collected for taxonomic groups of larvae at our samphng location The majonty of Invertebrate larvae were palatable to consumers Most predators readily consumed polychaete larvae barnacle naupln, blvalve veligers shnmp zoeae, crab megalopae, phoronld actlnotrochs, and hemlchordate tornana (which together accounted for 65 "L of meroplankton abundance) s u g g e s t~n g that these larvae lacked effective morpholog~cal or chem~cal defenses Agalnst at least 1 fish predator, a significant number of gastropod vel~gers, barnacle cypnds, crab Loeae, and stomatopod larvae (which accounted for 34 % of meroplankton abundance) appeared to be morphologically defended Larvae from these groups tended to b e rejected whole, but \yere consumed by flshes once they were crushed A significant number of nemertean pilidia asterold biplnnana and c n~d a n a n planulae (which accounted for only 0 2 % of meroplankton abundance) were rejected both whole and crushed suggest~ng that some species or indlvlduals withln these taxa may be chemcally defended Thus, the majonty of larvae from t h s assemblage of temperate meroplankton lacked physlcal or chemlcal defenses a g a~n s t potential predators (3 flshes and 1 cnidallan) Among the remalrung larvae, physical resistance to predators was much more common t h~i n chemical resistance

“…While dispersal and recruitment of many coastal brachyuran crab larvae are triggered by diurnal and tidal patterns as well as hydrological variables (DeVries et al, 1994;Macintosh et al, 1999;Pineda et al, 2007), no such patterns could be detected to date for S. serrata, due to insufficient sampling effort.…”

The mud crab Scylla serrata is a highly exploited species, associated to mangrove ecosystems in the Indo-West-Pacific. It has a complex life cycle with a dispersing larvae phase, and benthic juveniles and adults. The former are stenohaline depending on high-salinity conditions to survive, whereas the latter are physiologically well adapted to changing temperatures and salinities, conditions that typically occur in mangrove habitats. Movement and habitat use of large juveniles and adults are well studied, and these life stages are known to utilize and move between various habitats within the mangrove ecosystem: intertidal flats as well as subtidal channels and flats. Females undertake long movements from brackish inshore waters to waters with oceanic conditions for spawning. Sensory abilities-of early stages and adult stageshave hardly been studied, and little is known about larval and early benthic stages in the wild. Summarizing, the literature revealed substantial gaps in the understanding of the spatiotemporal dynamics of the different life stages and of the clues that trigger recruitment, movement, and other behavior. This is the first comprehensive review on the life history, movement patterns, habitat use, and systemic role of S. serrata with emphasis on the respective life stages and geographic differences. We emphasize the need for further research into these processes as a basis for the sustainable management and conservation of this species.
