Abstract The Stomatopoda of Korea have, in general, been poorly studied, with eight species recorded to date. A recent study of stomatopods collected by SCUBA diving and commercial fishing trawlers from Korean waters, however, resulted in the discovery of first records of six species from the study area. Among them, four belong to the superfamily Squilloidea Latreille, 1802 [Levisquilla inermis (Manning, 1965), Levisquilla jurichi (Makarov, 1979), Anchisquilla fasciata (De Haan, 1844), and Cloridopsis scorpio (Latreille, 1828)], and two belong to the Lysiosquilloidea Giesbrecht, 1910, one each in Tetrasquillidae Manning & Camp, 1993 [Acaenosquilla latifrons (De Haan, 1844)] and Nannosquillidae Manning, 1980 [Acanthosquilla multifasciata (Wood-Mason, 1895)]. Thus, fourteen species of Stomatopoda are now known from Korea. The superfamily Lysiosquilloidea is reported for the first time from Korean waters. A key to the species of Korean mantis shrimps is provided.

Abstract Here, the symbiotic palaemonid shrimp Hamodactylus boschmai is recorded from Korean waters for the first time, based on specimens collected from different invertebrate hosts by trimix diving at depths of between 45 and 60 m in Jejudo Island. This species can readily be distinguished from its congeners by the presence of a distinct supraorbital tooth, the proximal segment of the antennular peduncle having a single tooth on the distolateral margin, the presence of a denticulate lamina along the entire cutting edge of the fingers of the first pereiopod chela, and the chela of the second pereiopods having a strongly hooked tip on the movable finger. An illustrated description, colour photographs, and a comparison of partial mitochondrial cytochrome c oxidase subunit I gene sequences are provided.

Rotational Freedom

Almost all animals, regardless of the anatomy of the eyes, require some level of gaze stabilization in order to see the world clearly and without blur. For the mantis shrimp, achieving gaze stabilization is unusually challenging as their eyes have an unprecedented scope for movement in all three rotational degrees of freedom: yaw, pitch and torsion. We demonstrate that the species Odontodactylus scyllarus performs stereotypical gaze stabilization in the yaw degree of rotational freedom, which is accompanied by simultaneous changes in the pitch and torsion rotation of the eye. Surprisingly, yaw gaze stabilization performance is unaffected by both the torsional pose and the rate of torsional rotation of the eye. Further to this, we show, for the first time, a lack of a torsional gaze stabilization response in the stomatopod visual system. In the light of these findings, we suggest that the neural wide-field motion detection network in the stomatopod visual system may follow a radially symmetric organization to compensate for the potentially disorientating effects of torsional eye movements, a system likely to be unique to stomatopods.

Three amphipods of the family Photidae collected from Korean waters are reported here with detailed descriptions and illustrations. The Korean materials of Gammaropsis examined in this study are readily assigned to G. longipropodi by the characteristic shape of gnathopod 2 in males: not slenderly produced posterior margin of the carpus, uniform width of very elongate propodus, and the transverse palm. Among the species of genus Photis, P. fischmanni is only one species bearing stridulation ridges of the basis on gnathopod 2 and coxa 3 simultaneously in females, until now. However, Photis stridulus sp. nov. also show this characteristic but is clearly distinguishable from P. fischmanni by the weak setation of the appendages, smaller eye on the anterior cephalic lobe, and the slender carpus and propodus on gnathopod 1. The genus Podoceropsis is recorded from Korean waters for the first time with the discovery of P. clavapes sp. nov. This new species is characterized by its elongate propodus and dactylus on gnathopod 2 and the shape of the posterior lobe of the basis on pereopod 5 in mature males.

In this paper, seven new species of the family Photidae from Korean waters are described and illustrated in detail. Among them, Exiliphotis petilasp. nov. is a monotype of the newly reported Exiliphotisgen. nov., which is characterized by slenderer and more elongate pereopods 5–7 than those of other genera of the family Photidae. The genus Latigammaropsis is reported for the first time from Korean waters based on the description of Latigammaropsis careocavatasp. nov., which is differentiated from other Gammaropsis group by having weakly sexual dimorphic gnathopods 2, those have simple palmar margins in both sexes. Three new species of Photis are also described: Photis broncasp. nov., Photis posterolobussp. nov., and Photis longicarpussp. nov. The formerly misidentified Photis longicaudata from Japan and China as well as the Korean material could be classified as a new species, P. broncasp. nov. For that, the syntypes of P. longicaudata were re-examined, and lectotype and paralectotypes were newly designated in this study. Photis broncasp. nov. is characterized by quadrate tooth on the palmar margin medially on gnathopod 2 in both sexes. Photis posterolobussp. nov. shows a pointed posterior lobe on the ischium and a well-developed process of the propodus on male gnathopod 2. Photis longicarpussp. nov. can be distinguished from other species of the genus by very elongate carpus of male gnathopod 1. Two new species belonging to the genus Podoceropsis are also reported: Podoceropsis insinuomanussp. nov. has a strongly bisinuous palmar margin on male gnathopod 2, and Podoceropsis pseudoclavapessp. nov. differs from the closely related species of Podoceropsis clavapes by different shape of the palmar margin and shorter dactylus of male gnathopod 2. Additionally, a key to the Korean species of Photidae is provided.

The Polyclad fauna of the northwest Tunisian coasts is still unexplored. This is the first investigation of Polyclad flatworms collected by scuba diving in Tunisian waters. Three species belonging to three different families and three different genera are reported and re-described. Echinoplana celerrima (Haswell, 1907) was found to feed on the ascidian Ciona intestinalis (Linnaeus, 1767) at 20 m of depth and Thysanozoon brocchii (Risso, 1818) was observed to eat on sponges Dysidea tupha (Martens, 1824) at 16 m of depth. Prosthiostomum siphunculus (Delle Chiaje) was found creeping on stones at 29 m of depth. Some anatomical data of living specimen of P. siphunculus and fixed specimens of T. brocchii were provided for the first time.

Background: The experience of Recreational SCUBA Diving (RSD) is unique and exciting because participants can feel innermost and special sensations. Aim: By exploring the role of the senses in RSD This paper seeks to illustrate the complex, kaleidoscopic and inter-relational connections beginner SCUBA divers make with aquatic environment within the sensorium experience for the first time. Methods: The present research draws upon the qualitative inquiry away from the positivist approaches to capture insider views, meanings, and interpretations. Audio-recorded semi-structured interviews with a convenience sample of 12 undergraduate students who had experienced a first-time SCUBA diving through Discover SCUBA Diving (DSD) Program were transcribed and thematically analyzed. A thematic analysis was performed with the Nvivo 11 Plus software package program. Results: Analysis illustrated that both positive and negative emotions are experienced due to (a) Diver Dimension of Marine Wildlife Touching, (b) Diver Dimension of Marine Wildlife Viewing, and (c) Diver Dimension of Marine Wildlife Hearing. Conclusion: The opportunity to experience aquatic environment for the first time during active leisure reflects participants’ ability, which offers encouragement, enthusiasm, well-being, and satisfaction. In unravelling the negative diving experience, as experienced by divers, we argue some physical and psychological distress and difficulty arise due to chemical and physical properties of aquatic environment, however. Keywords: Active Leisure, Aquatic, Sensorium, SCUBA Diving, Well-being.

The present study describes five newly recorded modern benthic foraminiferal species from the subtidal zone near Jeju Island and East China Sea (Korea). The newly recorded species (Karrerulina conversa, Rotaliammina trumbulli, Vertebralina striata, Pegidia dubia and Amphistegina radiata) belong to five families (Prolixoplectidae, Trochamminidae, Fischerinidae, Pegidiidae and Amphisteginidae), three orders (Lituolida, Miliolida and Rotaliida) and two classes (Globothalamea and Tubothalamea). All these five genera (Karrerulina, Rotaliammina, Vertebralina, Pegidia and Amphistegina) were also reported for the first time from Korean waters. Most of the examined specimens were highly consistent morphologically with previous records from southern China and Japan. Additionally, Amphistegina is one of the symbiont-bearing larger benthic foraminifera, known to be mainly distributed in tropical to warm subtropical waters. This study contributes to the expansion of data on the recent foraminiferal species diversity in Korean waters.

Commercial fishing of estuarine tapertail anchovy (Coilia nasus), an important anadromous fish species in the Yangtze River of China, has been prohibited due to the serious damage overfishing has caused to the wild population. Research regarding the energy metabolism is important for migratory fish to ensure the continuation of their existence. In this study, we performed, for the first time, a comparative transcriptome analysis of the liver of C. nasus subjected to long-term starvation stress. The results indicated that the damaging effects involved downregulation of the antioxidant capacity and immune response. The positive response to starvation involved upregulation of the anti-allergy and anticancer capacity, which supports the function of starvation in cancer inhibition, as has also been determined for human beings. This study revealed regulatory pathways, differentially expressed genes (DEGs), and mechanisms leading to damage of the liver in C. nasus affected by starvation. This research contributes information for the further study of the energy metabolism mechanism of C. nasus and provides a theoretical reference for starvation metabolism research of other fish species and even human beings.
