“…(Bentlage et al 2010). Though the genus Carybdea was recently revised by Straehler-Pohl et al (2017), it remains necessary to clarify the life cycle of C. marsupialis from the Mediterranean and other carybdeid species, and compare their morphologies with C. brevipedalia in the future.…”

“…Carybdea brevipedalia was incorrectly identified as Carybdea rastonii by many biologists in the past (Uchida 1929, 1970, Kramp 1961. However, recent taxonomic investigations and molecular phylogenetic analyses suggest that C. rastonii from Japanese waters should be regarded as C. brevipedalia (Bentlage et al 2010, Straehler-Pohl et al 2017.…”

Envenomation by toxic box jellyfish species is known to be a serious problem to public health. In order to elucidate the problem, it becomes necessary to predict the occurrence of box jellyfishes, as well as understanding their ecology and life cycle. Mature medusae of Carybdea brevipedalia (Cubozoa: Carybdeida), which is a common species of box jellyfish in Japan, were collected from northern Japan to observe its early life history, including polyp formation. Fertilization occurred externally, and blastulae developed into planulae. Free swimming planulae settled and metamorphosed into tiny primary polyps with two forms, i.e. settled and creeper. Adult polyps formed cysts at temperatures below 15°C or when water replacement and/or feeding was stopped. Budding occurred in four-tentacled polyps, and the buds were released after commencement of budding. Complete metamorphosis of a whole polyp into a single medusa occurred at stable temperatures between 18 to 25°C (18, 20, 23, 25°C, respectively) or when temperatures were raised from 20 to 25°C. Newly released medusae had four tentacles. Our study demonstrated that polyps of C. brevipedalia survive and propagate over a wide range of water temperatures and that developmental features resemble closely those of some tripedaliid species, namely Tripedalia cystophora and Copula sivickisi, rather than Carybdea marsupialis. The morphological affinities of polyp in C. brevipedalia, T. cystophora and C. sivickisi support recent molecular results. However, further studies are needed to confirm the morphological contradiction between C. brevipedalia and C. marsupialis in the future.

“…Members of the class Staurozoa are interpreted as attached medusoid forms, and are usually found in cold waters [2]. The class Cubozoa [3] has been documented off Southern California by a single species collection in San Diego County [4]. An additional class Endocnidozoa, consisting of small parasitic forms in the subclasses Polypodiozoa-[5] and Myxozoa [6] has recently been proposed.…”

Diversity and life-cycle analysis of Pacific Ocean zooplankton by videomicroscopy and DNA barcoding: Hydrozoa

Most, but not all cnidarian species in the class Hydrozoa have a life cycle in which a colonial, asexually reproducing hydroid phase alternates with a free-swimming, sexually reproducing medusa phase. They are not well known, in part because many of them are microscopic, at least in the medusa phase. Matching the two phases has previously required rearing of the organism from one phase to another, which has not often been possible. Here we show that DNA barcoding makes it possible to easily link life-cycle phases without the need for laboratory rearing. Hydrozoan medusae were collected by zooplankton tows in Newport Bay and the Pacific Ocean near Newport Beach, California, and hydroid colonies were collected from solid substrates in the same areas. Specimens were documented by videomicroscopy, preserved in ethanol, and sent to the Canadian Centre for DNA Barcoding at the University of Guelph, Ontario, Canada for sequencing of the COI DNA barcode. In the order Anthoathecata (athecate hydroids), DNA barcoding allowed for the discrimination between the medusae of eight putative species of Bougainvillia, and the hydroid stages were documented for two of these. The medusae of three putative species of Amphinema were identified, and the hydroid stages were identified for two of them. DNA barcodes were obtained from medusae of one species of Cladonema, one adult of the by-the wind Sailor, Velella velella, five putative species of Corymorpha with the matching hydroid phase for one; and Coryne eximia, Turritopsis dohrnii and Turritopsis nutricula with the corresponding hydroid phases. The actinula larvae and hydroid for the pink-hearted hydroid Ectopleura crocea were identified and linked by DNA barcoding. In the order Leptothecata (thecate hydroids) medusae were identified for Clytia elsaeoswaldae, Clytia gracilis and Clytia sp. 701 AC and matched with the hydroid phases for the latter two species. Medusae were matched with the hydroid phases for two species of Obelia (including O. dichotoma) and Eucheilota bakeri. Obelia geniculata was collected as a single hydroid. DNA barcodes were obtained for hydroids of Orthopyxis everta and three other species of Orthopyxis. One member of the family Solmarisidae, representing the order Narcomedusae, and one member (Liriope tetraphylla) of the order Trachymedusae were recognized as medusae. The results show the utility of DNA barcoding for matching life-cycle stages as well as for documenting the diversity of this class of organisms.

10 11 Most, but not all cnidarian species in the classes Hydrozoa, Scyphozoa and Anthozoa have a life cycle in which a colonial, 12 asexually reproducing hydroid phase alternates with a free-swimming, sexually reproducing medusa phase that, in the 13 hydrozoans, is usually microscopic. Hydrozoan medusae were collected by zooplankton tows in Newport Bay and the 14 Pacific Ocean near Newport Beach, California, and hydroid colonies were collected from solid substrates in the same 15 areas. Specimens were documented by videomicroscopy, preserved in ethanol, and sent to the Canadian Centre for 16 DNA Barcoding at the University of Guelph, Ontario, Canada for DNA barcoding. 17 Among the order Anthomedusae (athecate hydroids), DNA barcoding allowed for the discrimination between the 18 medusae of eight putative species of Bougainvillia, and the hydroid stages were documented for two of these. The 19 medusae of three putative species of Amphinema were identified, and the hydroid stages were identified for two of 20 them. DNA barcodes were obtained from medusae of one species of Cladonema, one adult of the By-the wind Sailor, 21 Velella Velella, five putative species of Corymorpha with the matching hydroid phase for one; and Coryne eximia, 22 Turritopsis dohrnii and Turritopsis nutricula with the corresponding hydroid phases. The actinula larvae and hydroid for 23 the pink-hearted hydroid Ectopleura crocea were identified and linked by DNA barcoding. 24 Among the order Leptomedusae (thecate hydroids) medusae were identified for Clytia elsaeoswaldae, Clytia gracilis and 25 Clytia sp. 701 AC and matched with the hydroid phases for the latter two species. Medusae were matched with the 2 26 hydroid phases for two species of Obelia (including O. dichotoma) and Eucheilota bakeri. Obelia geniculata was collected 27 as a single hydroid. DNA barcodes were obtained for hydroids of Orthopyxis everta and three other species of 28Orthopyxis. 29The medusa of one member of the family Solmarisidae, representing the order Narcomedusae, and one member (Liriope 30 tetraphylla) of the order Trachymedusae were recognized as medusae. 31In the Scyphozoa, DNA barcoding confirmed the planktonic larval stage (ephyra) of the Moon Jelly, Aurelia aurita, the 32 adult medusa of which is occasionally common in and around Newport Bay. In the Anthozoa, antipathula larvae were 33 identified from the Onion Anemone, Paranthus rapiformis and a cerinula larva was identified from the Tube-dwelling 34 Anemone, Isarachnanthus nocturnus.We have yet to find the adults of these species locally. 35
