Seasonal succession of gelatinous zooplankton (medusae and ctenophores) from Mar del Plata Harbor, Argentina (SW Atlantic Ocean)

Ecología Austral, 2019
Temporal variation of the population dynamics of the medusae and ctenophores (gelatinous zooplankton) is described over an annual cycle in the Mar del Plata Harbor, Argentina.

A case of fatal cutaneous caput medusae hemorrhage

Clinical Case Reports, 2019
Key Clinical Message Alcoholic liver cirrhosis leads to portal venous hypertension, which can result in a caput medusae formation. Life‐threatening hemorrhage from a ruptured caput medusae vein is a rare complication.

Indoles induce metamorphosis in a broad diversity of jellyfish, but not in a crown jelly (Coronatae). [PDF]

PLoS ONE, 2017
Many animals go through one or more metamorphoses during their lives, however, the molecular underpinnings of metamorphosis across diverse species are not well understood.

Diagnostic dilemma of cystic biliary atresia: A series of two cases and brief review of the diagnostic modalities

JPGN Reports, EarlyView.
Abstract Cystic biliary atresia (CBA) is a rare variant of biliary atresia that closely resembles choledochal cyst (CC), complicating diagnosis and potentially delaying critical surgical intervention. We report two cases of CBA that were difficult to diagnose.

Cabomba caroliniana and Schoenoplectus californicus as Antifouling Candidates: Anti‐Attachment and Toxicological Effects in Aurelia coerulea (Cnidaria, Scyphozoa)

Environmental Toxicology, EarlyView.
ABSTRACT Biofouling on artificial surfaces in aquatic ecosystems leads to significant economic losses. Current antifouling paints, while effective, often harm the aquatic environment. This study explores ecologically safe antifouling alternatives derived from plants, focusing on the aquatic macrophytes Cabomba caroliniana (CC) and Schoenoplectus ...

The hydroid and medusa of Sarsia bella sp. nov. (Hydrozoa, Anthoathecatae, Corynidae), with a correction of the life cycle of Polyorchis penicillatus (Eschscholtz)

Scientia Marina, 2000
A new hydrozoan, Sarsia bella sp. nov. is described in both its hydroid and medusa stage from north of Puget Sound, Washington in the San Juan Islands, USA and off the southernmost tip of Vancouver Island, Canada.

Ontogenetic transitions, biomechanical trade-offs and macroevolution of scyphozoan medusae swimming patterns

Scientific Reports, 2023
Ephyrae, the early stages of scyphozoan jellyfish, possess a conserved morphology among species. However, ontogenetic transitions lead to morphologically different shapes among scyphozoan lineages, with important consequences for swimming biomechanics ...

Dietary resilience of coral reef fishes to habitat degradation

Journal of Animal Ecology, EarlyView.
Metabarcoding of gut contents shows that two common benthic‐feeding reef fishes with different feeding stratgies—a butterflyfish (Chaetodon capistratus) and a hamlet (Hypoplectrus puella)—shift diets on degraded reefs. These shifts mirror contrasting patterns in body condition: butterflyfish showed strong individual variation, whereas condition was ...

Life in tidepools: distribution and abundance of two crawling hydromedusae, Staurocladia oahuensis and S. bilateralis, on a rocky intertidal shore in Kominato, central Japan

Scientia Marina, 2000
Two crawling medusae, Staurocladia oahuensis (Edmondson, 1930) and S. bilateralis (Edmondson, 1930) were found to be abundant in intertidal rock pools in Kominato from late summer until early winter.
