Coevolution of the Tlx homeobox gene with medusa development (Cnidaria: Medusozoa)
Communications Biology, 2023 Cnidarians display a wide diversity of life cycles. Among the main cnidarian clades, only Medusozoa possesses a swimming life cycle stage called the medusa, alternating with a benthic polyp stage.

Full‐year in situ imaging reveals fine‐scale habitat differences among salp and doliolid life stages
Limnology and Oceanography, Volume 71, Issue 7, July 2026.Abstract Doliolids and salps are pelagic tunicates that reproduce both asexually and sexually during their life history, occasionally forming massive blooms (> 1000 ind. m−3) that can clear large volumes of water daily. Although blooms of doliolids and salps are often associated with pulses of primary productivity, little is understood about their life

Phylogenetic analysis of Leptothecata (Hydrozoa; Hydroidolina) and evolution of metagenesis [PDF]
, 2014 Na pesquisa evolutiva do grupo Hydrozoa, um dos maiores desafios continua sendo a proposta de relações históricas entre grandes grupos. A partir de um ciclo de vida \"tradicional\" nos Medusozoa, determinado pela metagênese (a geração da fase adulta ...

Freshwater Biology, Volume 71, Issue 7, July 2026.ABSTRACT Biological invasions pose major threats to ecosystems, with aquatic habitats particularly vulnerable due to high connectivity and biodiversity. The Ponto‐Caspian region is widely recognised as a major source of highly invasive non‐native aquatic species, yet a global synthesis of their spatial, taxonomic and temporal invasion patterns has been

Additional notes on Clathrozoella drygalskii (Vanhöffen, 1910) (Cnidaria, Hydrozoa)
Scientia Marina, 2000 Study of the material of Clathrozoella drygalskii (Vanhöffen, 1910), a hydroid initially referred to the thecate hydroids but probably better classified in athecate hydroids along with such families as Hydractiniidae and Solanderiidae, has been continued

Approaches to the ethology of hydroids and medusae (Cnidaria, Hydrozoa)
Scientia Marina, 2000 The behavioural patterns of 26 species of Antho- and Leptomedusae (with or without medusa stage) were investigated by video recordings. The analysed activities were: answers to mechanical stimuli, prey capture and ingestion, digestion, egestion, and ...

Pest Management Science, Volume 82, Issue 6, Page 5184-5194, June 2026.Gene‐specific double‐stranded RNAs effectively silence essential genes in the invasive citrus pest Delottococcus aberiae, leading to significant mortality through both microinjection and oral delivery. These results provide proof of concept for RNA interference‐based biopesticides as selective and sustainable tools for citrus integrated pest management.
