    ResearchGate
    A new subfamily of ulmarid scyphomedusae, the Santjordiinae, with a description of Santjordia pagesi gen. et sp. nov. (Cnidaria: Scyphozoa: Discomedusae: Semaeostomeae: Ulmaridae) from the Sumisu Caldera, Ogasawara Islands, Japan
    An undescribed species of ulmarid medusa was observed in situ and captured at 812 m depth within the Sumisu Caldera, Ogasawara Islands, Japan. Morphological and molecular evidence points to it being distinct from other ulmarid medusae and a new species

    Ontogenetic transitions, biomechanical trade-offs and macroevolution of scyphozoan medusae swimming patterns
    Cnidarians are one of the first metazoans to develop locomotion propelled by muscle contractions and their swimming modes are highly associated to the medusae bell shapes1. Medusae with more prolate bells, or streamlined bodies, quantified as bell fineness

    What is a Scyphomedusae (class Scyphozoa)?
    Scyphomedusae (class Scyphozoa) are exclusively marine organisms divided into two monophyletic lineages: Coronatae Vanhöffen, 1892 (= Coronamedusae, 59 spp.) and Discomedusae (172 spp.) 10. Discomedusae is composed of "Semaeostomeae" L. Agassiz, 1862 (84 spp.) and Rhizostomeae Cuvier, 1800 (88 spp.) 11.

    Does body size affect fmean 1 in Scyphomedusae?
    Scyphomedusae had a typically flattened or oblate bell with fmean < 1 (Fig. 1 A). In medusae of “Semaeostomeae”, no significant effect of body size on fmean was found. This indicates that each species has a particular pattern of bell shape development that cannot be predicted by pooling species of this order together.

    Do Scyphomedusae have more robust swimming patterns than Rhizostomeae?
    By contrast, medusae of the order Rhizostomeae (n = 4 spp. studied) appear to have more robust swimming patterns, pulsing at higher frequencies (~ 2 Hz), and reaching higher velocities and Reynolds numbers than other scyphomedusae of similar size diameter 4, 16, 23.

    What is ontogeny in Scyphomedusae?
    Ontogeny in scyphomedusae involves remarkable alterations in the bell morphology that lead to different swimming kinematic patterns and performances.
