“…Scyllarides squammosus of the family Scyllaridae belongs to a taxon of slipper lobsters with four subfamilies, 88 species, and two subspecies (Wardiatno et al 2016) , previously thought to be 89 species (Yang et al 2012) . Although knowledge of S. squammosus has increased in recent years, scientific information is still limited and focused on only a few species (Lavalli and Spanier 2007;Lavalli et al 2020) , compared to the highly commercialized spiny lobsters of the Nephropidae and Palinuridae families (Spanier and Lavalli 2013) . This species can be distinguished by its last antennal segment, which is completely reduced to a flat plate and is used as a steering device to escape from predators (Wardiatno et al 2016) .…”

Socio-ecological systems (SESs) have emerged to incorporate the perspectives of multiple stakeholders when attempting to solve wicked problems related to fishery management (Vasslides and Jensen 2016) . This is difficult because of the complexity of fisheries' SES, a term used to refer to the different components and relationships between the fisheries' resource system, the natural environment, and various stakeholders (Kittinger et al. 2013;Murphy et al. 2021) . For example, in this case study, the biological and ecological attributes obtained through literature reviews were then associated with fisherpersons and fisheries cooperative association(FCA)officials, resulting in outcomes that affected both ecological and economic systems.

“…These legs do not extend widely beyond the body, suggesting that they were probably not suited to be used as a raptorial appendage, capturing prey from afar. The distal claw-shaped podomere and adjacent podomere with elongated spines of Tuzoia could have been used similar to the pereopods in benthic slipper lobsters [94], which are used to capture sessile, slow-moving prey or handle carcasses in the proximity. These legs are also reminiscent of the maxillipeds in several crustacean taxa [95,96], which have a primarily locomotory function but can also handle prey or tissues and bring them to the mouthparts [97].…”

The origin of mandibulates, the hyperdiverse arthropod group that includes pancrustaceans and myriapods, dates back to the Cambrian. Bivalved arthropod groups such as hymenocarines have been argued to be early mandibulates, but many species are still poorly known, and their affinities remain uncertain. One of the most common and globally distributed Cambrian bivalved arthropods is Tuzoia . Originally described in 1912 from the Burgess Shale based on isolated carapaces, its full anatomy has remained largely unknown. Here, we describe new specimens of Tuzoia from the Canadian Burgess Shale (Wuliuan, Cambrian) showcasing exceptionally preserved soft tissues, allowing for the first comprehensive reconstruction of its anatomy, ecology and evolutionary affinities. The head bears antennae and differentiated cephalic appendages. The body is divided into a cephalothorax, a homonomous trunk bearing ca 10 pairs of legs with heptopodomerous endopods and enlarged basipods, and a tail fan with two pairs of caudal rami. These traits suggest that Tuzoia swam along the seafloor and used its spinose legs for predation or scavenging. Tuzoia is retrieved by a Bayesian phylogenetic analysis as an early mandibulate hymenocarine lineage, exemplifying the rapid diversification of this group in open marine environments during the Cambrian Explosion.

This study was conducted to verify the essentiality of dietary cholesterol for early juvenile slipper lobster, Thenus australiensis (initial weight 4.50 ± 0.72 g, mean ± SD, CV = 0.16), and to explore the potential for interactions between dietary cholesterol and phospholipid. An 8-week experiment was conducted using six experimental feeds containing three supplemental cholesterol concentrations (0, 0.2 and 0.4% dry matter) at two supplemental phospholipid concentrations (0% and 1.0% dry matter). Dietary cholesterol concentrations of ≥ 0.2% resulted in up to threefold greater weight gain compared to 0% dietary cholesterol, but without any significant main or interactive dietary phospholipid effect. An interaction was observed for lobster survival with lowest survival (46%) recorded for combined 0% cholesterol and 0% phospholipid compared to every other treatment (71–100%). However, all surviving lobsters at 0% dietary cholesterol, regardless of dietary phospholipid level, were in poor nutritional condition. Apparent feed intake (AFI) was significantly higher at dietary cholesterol ≥ 0.2% but was lower for each corresponding dietary cholesterol level at 1% dietary phospholipid. This implied that the feed conversion ratio was improved with supplemental phospholipid. In conclusion, this study confirms the essential nature of dietary cholesterol and that dietary phospholipid can provide additional benefits.
