The stings of box jellyfishes can be fatal, so knowing the fauna of a certain area is important to save lives. Five described and two still-undescribed species of Cubozoa have been reported from Thailand: Chironex indrasaksajiae, Chironex sp., Chiropsella sp., Chiropsoides buitendijki, Copula sivickisi, Morbakka fenneri, and Tripedalia cystophora. We made detailed observations of the morphology of two of the species newly recorded in Thailand: Alatina morandinii and Tripedalia binata. The molecular phylogeny of these species is also discussed. Additional investigations are needed to understand the diversity of Cubozoa in Thailand.

The order Coronatae is a unique group, with the following characters distinguishing them from other scyphozoans: a coronal furrow, a coronate pedalium, and oocytes that develop without accessory pigments. Coronatae polyps are enclosed in chitinous tubes and produce multiple ephyrae via polydisk strobilation. So far, eleven described species of Coronatae have been reported in Japanese waters: Atolla wyvillei, Atolla vanhoeffeni, Atolla russelli, Atorella vanhoeffeni, Atorella japonica, Nausithoe punctata, Palephyra pelagica, Periphylla periphylla, Periphyllopsis braueri, Stephanoscyphistoma corniformis and Nausithoe racemosa. The present study reports detailed observations of the morphology of one species newly recorded in Japan: Linuche draco. Development from ephyra to mature medusa was observed and recorded. Additional investigations are needed to understand the diversity of the order Coronatae in Japan.

In this study, we investigated the trophic interactions between the Japanese giant box jellyfish, Morbakka virulenta, and fish in the central part of the Seto Inland Sea, western Japan, in autumn and winter. Occurring in the surface waters at nighttime, these cubomedusae, regardless of their size (1.5 to 22.5 cm in bell height), were found to be piscivorous, feeding mainly on the Japanese anchovy, as shown by their stomach contents analysis. This finding was supported by a stable isotopic analysis and by an unchanged cnidome, irrespective of the bell height of medusae. Their nocturnal occurrence near the surface often took place around the slack tide, during which the medusae were foraging with tentacles fully extended. Other associations between the medusae and fish were also observed at this time: presumed commensalism with juvenile Japanese horse mackerel, and predation by black scraper.

A new hydromedusa belonging to the order Anthoathecata is reported from Sagami Bay, eastern Japan. Tiaricodon orientalis sp. nov. can be distinguished from other Tiaricodon species by the umbrella size of the medusa, manubrium length, interradial peaks in the subumbrella, and a red band on the upper part of the manubrium. A comparative table of the primary diagnostic characters of the genus is provided. Our morphological and molecular phylogenetic analyses suggest that Tiaricodon from China is not Tiaricodon coeruleus but Tiaricodon orientalis.
