THE METAMORPHOSIS OF THE ANTHOMEDUSA, POLYORCHIS KARAFUTOENSIS KISHINOUYE [PDF]
, 1970 One of the highest Anthomedusa, Polyorchis karafutoensis was first described by KISHINOUYE (1910) from Sakhalin. Since then the medusa was sometimes reported from the southern coast and the eastern lagoon of Sakhalin and the eastern part of Hokkaido ...

Limnology and Oceanography: Methods, Volume 23, Issue 1, Page 67-86, January 2025.Abstract Various iterations of shadowgraph imaging have been used to quantify zooplankton in situ with high spatial resolution. Because these systems can image relatively large volumes of water, they are especially useful for resolving less common meso‐ or macrozooplankton taxa (< 50 ind. m−3), such as larval fishes and gelatinous animals.

Frontiers in Marine Science, 2020 Interactions between predators and their prey are important in shaping planktonic ecosystems. However, these interactions are difficult to assess in situ at the spatial scales relevant to the organisms.

The Numerical Comparison of Flow Patterns and Propulsive Performances for the Hydromedusae Sarsia Tubulosa and Aequorea Victoria [PDF]
, 2009 The thrust-generating mechanism of a prolate hydromedusa Sarsia tubulosa and an oblate hydromedusa Aequorea victoria was investigated by solving the incompressible Navier–Stokes equations in the swirl-free cylindrical coordinates.

The Anatomical Record, Volume 307, Issue 11, Page 3437-3505, November 2024.Abstract The humerus is central for locomotion in turtles as quadrupedal animals. Osteological variation across testudine clades remains poorly documented. Here, we systematically describe the humerus anatomy for all major extant turtle clades based on 38 species representing the phylogenetic and ecological diversity of crown turtles.

Fluorescence patterns and diversity of hydrozoans from Bocas del Toro, Panama
Ciencias MarinasMany metazoans contain molecules capable of fluorescence, the absorption and re-emission of light. Since the anatomical distribution, or patterning, of these molecules is variable across taxa, patterns of fluorescence may serve as a powerful diagnostic ...

Biodiversity and spatial distribution of medusae in the Magellan Region (Southern Patagonian Zone)
Latin American Journal of Aquatic Research, 2014 Epipelagic medusae collected in the Magellan Region (Southern Patagonian Zone) during spring 2009 were analyzed. A total of 27 species of medusae were identified (25 hydromedusae and 2 scyphomedusae).

Two Species of Koellikerina Medusae (Cnidaria, Hydrozoa, Anthomedusae) from Japan [PDF]
, 2005 We fully described two Koellikerina species from shallow waters in Japan with illustrations and photographs. Koellikerina constricta (Menon, 1932), bearing characteristic bell constriction, expands its distribution to Kuchinoerabu Island, Kagoshima ...

Science, 1900 THE announcement of Bateson ('94), that "in the whole range of natural history there is no more striking case of the discontinuity and perfection of meristic variation than in the genus Sarsia, and the further proposition whether it is a mere coincidence that the specimens presenting this variation, so rare among the free-swimming Hydromedusae, should ...

Functional and Character Disparity Are Decoupled in Turtle Mandibles
Ecology and Evolution, Volume 14, Issue 11, November 2024.Here, we compare functional disparity measured by biomechanical proxies and character disparity measured by discrete morphological characters in turtle jaws. Exploration of mandibular patterns reveals that several biomechanical configurations or character state combinations can lead to the same feeding type (i.e., convergence) or that high functional ...
