Coevolution of the Tlx homeobox gene with medusa development (Cnidaria: Medusozoa)

open access: yesCommunications 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.

In situ predation of Boops boops (Linnaeus, 1758) on the rare hydrozoan, Geryonia proboscidalis (Forsskål, 1775), in the Aegean Sea, Turkey

open access: yesTurkish Journal of Agriculture: Food Science and Technology, 2017
Most data of fish feeding on cnidarians were obtained from the studies on gut contents of the predators rather than in situ observations. The feeding observation of Boops boops on Geryonia proboscidalis was observed in September 2013, in Sığacık Bay, the

Fluctuation and diversity of Hydromedusae (Hydrozoa, Cnidaria) in a highly productive region of the Gulf of Mexico inferred from high frequency plankton sampling [PDF]

open access: yesPeerJ, 2019
Hydrozoa medusae undergo blooms and seasonal fluctuations; however the drivers of such fluctuations are unknown. To understand how medusa populations fluctuate in response to seasonal factors such as temperature, salinity, dissolved oxygen, and ...

The complete mitochondrial genome of the hydrozoan jellyfish Spirocodon saltatrix (Cnidaria; Hydrozoa; Anthoathecata) with phylogeny analysis

open access: yesMitochondrial DNA. Part B. Resources, 2020
In the present study, we sequenced and analyzed the complete mitochondrial genome of the hydrozoan jellyfish Spirocodon saltatrix. The mitochondrial genome was a linear form (15,752 bp long, 70.4% AT), consisting of 13 protein coding genes (cox1, cox2 ...

Additional notes on Clathrozoella drygalskii (Vanhöffen, 1910) (Cnidaria, Hydrozoa)

open access: yesScientia 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

The genome sequence of a hydroid, Candelabrum cocksii (Cocks, 1854). [PDF]

open access: yesWellcome Open Res
We present a genome assembly from an individual Candelabrum cocksii (hydroid; Cnidaria; Hydrozoa; Anthoathecata; Candelabridae). The genome sequence is 232.9 megabases in span. Most of the assembly is scaffolded into 15 chromosomal pseudomolecules.

Approaches to the ethology of hydroids and medusae (Cnidaria, Hydrozoa)

open access: yesScientia 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 ...

Photosynthetic planulae and planktonic hydroids: contrasting strategies of propagule survival

open access: yesScientia Marina, 2000
Settlement delays can be important to prevent propagule waste when proper settling substrates are not immediately available. Under laboratory conditions, the planulae of Clytia viridicans underwent two alternative developmental patterns.
