“…In these species, a noticeable morphological change was observed in the digestive system during metamorphosis, which showed as well as a reduction of the mandibles and the setal number in the external feeding apparatus and showed an underdeveloped foregut (Nishida et al 1990, Wolfe and Felgenhauer 1991, Mikami and Takashima 1993, Lemmens and Knott 1994. Abrunhosa and Kittaka (1997a, b) observed similar facts in king crab species of the genus Paralithodes (important fishery resource of the North Pacific) during the megalopal stage.…”

“…Many studies have focused on the morphological and functional aspects of the foregut in adult decapod specimens (Meiss and Norman 1977, Kunze and Anderson 1979, Suthers and Anderson 1981, Suthers 1984, Skilleter and Anderson 1986, Mikami and Takashima 1993, Pinn et al 1999, Jha and Homechaudhuri 2001, Brosing et al 2002, Castro and Bond-Buckup 2003, however, very few efforts to investigate these aspects in the larval stages have been undertaken in the past. Therefore, in this present study, the morphology of the larval foreguts of two decapod crabs from the Northern Brazil, Uca vocator Herbst 1804 (Ocypodidae) and Panopeus occidentalis Saussure 1857 (Xanthidae) were investigated, and the functionality of these organs is discussed in detail.…”

Feeding is an important factor for the successful rearing of larvae of the crab species. Further information on the morphological features of the foregut may to reveal larval feeding behaviour and or/whether there is a lecithotrophy in some or even in all stages of the larval cycle. In the present study, the structural development of the foregut and their digestive functions were examined in larvae of two brachyurans, Uca vocator and Panopeus occidentalis, reared in the laboratory. During larval development, the foreguts of the larvae in the first and last zoeal stages and in the megalopa stage were microscopically examined, described and illustrated. The zoeal foreguts of both species were well developed, showing specialization with a functional cardiopyloric valve and a filter press. The megalopa stage had a complex and specialized gastric mill similar to that found in adult crabs with the appearance of rigidly calcified structures. These results support the hypothesis that the feeding behaviour of each larval stage is directly related to the morphological structure of the foregut. Such facts strongly indicate that all larval stages of both U. vocator and P. occidentalis need an external food source before completing the larval development in a planktonic environment.

Scyllarid lobsters, together with the palinurids, have a long-lived, planktonic phyllosoma larval phase in their early life history followed by a much briefer postlarval phase which at settlement completes the planktonic period of their life cycle. Information on scyllarid larval biology and recruitment mechanisms is fragmentary. Scyllarid species exhibit a wide range of larval recruitment strategies and durations, from entire larval and postlarval phases being completed in just a few weeks within lagoons, through to species that become widely dispersed in ocean basins over many months. In contrast, the phyllosomas of all palinurids so far investigated invariably, over many months, become widely dispersed in the open ocean well beyond the continental shelf. Among scyllarid species a general relationship is apparent between adult size and the extent of larval dispersal. During the planktonic period currents, in combination with larval vertical migratory behaviour, probably play an important role in larval dispersal and return. Although varying greatly in size, the postlarval nisto of most scyllarids appears to be similar in behaviour to the puerulus of palinurids. Nistos are usually (if not always) nonfeeding and appear to alternate between swimming at night and resting on the bottom during the day as they move inshore to regain adult grounds before settling and metamorphosing to the first juvenile lobster instar. Those scyllarids with a somewhat abbreviated larval duration and mainly coastal larval distribution-the "flat" species of Ibacus and Thenus-appear to have succeeded in exploiting local currents and biotic systems to restrict larval dispersal and maintain their place. Based on the characteristics of the larvae and their recruitment mechanisms, there is support for the present division of the Scyllaridae into its four subfamilies, but also backing for revision, particularly of the Ibacinae.

“…A number of studies have examined the feeding behaviour and morphology of the appendages and mouthparts in phyllosoma (Nishida et al 1990;mikami & Takashima 1993;Johnston & Ritar 2001;Nelson et al 2002;Cox & Johnston 2003;Johnston et al 2005). The observations from our study concurred with findings on the methods of phyllosoma food capture and consumption.…”

The ability of Panulirus ornatus phyllosoma to capture, feed and process diets of different texture and particle size were studied during developmental stages I, III and V. Diets were captured using the spines and dactyl on the second and third pereiopods and brought to the oral cavity assisted by the second and third maxillapeds. Optimal capture was obtained when diets were a gelatinous-muscular consistency, and hard particles were caught when embedded in a muscular carrier. A range of food textures, from gelatinous to hard, were able to be masticated in the oral cavity by stage V phyllosoma. Masticated particles were filtered by phyllosoma through spines and hairs in the proventriculum, during stages I-II, and a filter press in stages III-V. Maximum particle size passing into the midgut gland for digestion was 7, 3 and 0.5 //m in stage I, III and V phyllosoma, respectively. B cells were prominent in the proximal ends of the caece of stage V phyllosoma and were visible in live animals under light microscopy.
