Swimming ability of the Carybdea marsupialis (Cnidaria: Cubozoa: Carybdeidae): implications for its spatial distribution

Journal of Zoology, Volume 324, Issue 1, Page 1-10, September 2024.
In this paper we analyzed the swimming speed, effective velocity, effective displacement index (EDI) and proficiency of juvenile to adult specimens (ranging from 1.1 to 36 mm of the diagonal bell width) of the box jellyfish Carybdea marsupialis. Abstract Although usually considered part of the plankton, cubozoans are strong swimmers.

Stock discrimination of two European squids (Illex coindetii, Loligo forbesii) by statolith shape analysis

Fisheries Management and Ecology, Volume 31, Issue 3, June 2024.
Abstract We evaluated the feasibility of classifying ommastrephid and loliginid squid species by statolith shape analysis into fisheries management units or stocks. Statoliths of Illex coindetii (Verany, 1839) and Loligo forbesii (Steenstrup, 1856) were studied from multiple areas of the North East Atlantic and Northern Mediterranean Sea during 2021 ...

The habitat preferences of Idiosepius pygmaeus and their use of conspecific cues

Marine Ecology, Volume 45, Issue 3, June 2024.
Abstract The two‐toned pygmy squid (Idiosepius pygmaeus, Steenstrup, 1881) is a small, tropical cephalopod that inhabits seagrass meadows and is known to attach to blades of seagrass using a specialised adhesive organ. A global decline in seagrass habitat due to anthropogenic disturbances may threaten the species that rely on seagrass meadows for ...

Decapod crab zoeae as food for rearing cephalopod paralarvae [PDF]

Aquaculture, 1994
A simple method of providing a regular supply of live food for the experimental culture of paralarval cephalopods is described. The primary food source utilized was hatched zoeae of large laboratory populations of the hermit crab, Pagurus prideaux. Zoeal size, swimming behaviour, and distribution in the water column make these zoeae a suitable live ...

The role of DNA methylation on Octopus vulgaris development and their perspectives

Frontiers in Physiology, 2014
DNA methylation is a common regulator of gene expression and development in mammalian and other vertebrate genomes. DNA methylation has been studied so far in a few bivalve mollusk species, finding a wide spectrum of levels.

A new way to understand migration routes of oceanic squid (Ommastrephidae) from satellite data

Remote Sensing in Ecology and Conservation, Volume 10, Issue 2, Page 248-263, April 2024.
Estimating the migratory patterns of Ommastrephidae based on remote sensing is attractive and challenging; recorded jiggers do not chase a certain group of individuals (like tagging‐based tracking) but catch individuals in different ages and migration stages.

Performance Parameters of Paralarvae and Postparalarvae Rearing of Patagonian Red Octopus, Enteroctopus megalocyathus, under Experimental Conditions

Aquaculture Research, Volume 2024, Issue 1, 2024.
Patagonian red octopus, Enteroctopus megalocyathus, an interesting species for Chilean aquaculture diversification, requires the improving of their experimental technology to obtain early juveniles. The first objective of the study was to enhance aspects of feeding and temperature management in broodstock, egg incubation, paralarvae rearing, and early ...

Seasonal changes in paralarval cephalopod communities on the southwest coast of Baja California Sur (spring and autumn 2003)

Ciencias Marinas, 2018
We recorded seasonal changes in the paralarval cephalopod communities collected off the southwestern coast of Baja California Sur, Mexico, during 2003. Simultaneous surface and oblique trawls were carried out with CalCOFI-type nets and CTD casts during ...

Morphological and Molecular Characterization of Eggs and Paralarvae of Green Octopus, Octopus hubbsorum Berry 1953, from the Gulf of California

Diversity
The green octopus, Octopus hubbsorum, is a merobenthic species that inhabits warm-temperate waters in the eastern Pacific. However, its similarity to some morphological characteristics of and its slight genetic divergence from Octopus mimus has led to ...
