Developmental expression of “germline”- and “sex determination”-related genes in the ctenophore Mnemiopsis leidyi

EvoDevo, 2016
Background An essential developmental pathway in sexually reproducing animals is the specification of germ cells and the differentiation of mature gametes, sperm and oocytes. The “germline” genes vasa, nanos and piwi are commonly identified in primordial

Ctenophore population recruits entirely through larval reproduction in the central Baltic Sea [PDF]

, 2012
The comb jelly Mertensia ovum, widely distributed in Arctic regions, has recently been discovered in the northern Baltic Sea. We show that M. ovum also exists in the central Baltic but that the population consists solely of small-sized larvae (less than ...

From Notochord Formation to Hereditary Chordoma: The Many Roles of Brachyury

BioMed Research International, Volume 2013, Issue 1, 2013., 2013
Chordoma is a rare, but often malignant, bone cancer that preferentially affects the axial skeleton and the skull base. These tumors are both sporadic and hereditary and appear to occur more frequently after the fourth decade of life; however, modern technologies have increased the detection of pediatric chordomas.

Old Taxonomy Masks the Phenotypic Diversity of Pleurobrachia Fleming (Ctenophora: Tentaculata): An Analysis of the Morphological Variation in the Genus from Mexican Coasts

Diversity
Pleurobrachia pileus and P. bachei are among the most frequently recorded ctenophores worldwide. Despite their long-standing descriptions dating back nearly 250 years, their taxonomic boundaries remain ambiguous due to the lack of definitive diagnostic ...

Observations on the Ecology ofPleurobrachia Pileus(Ctenophora) in the Southern Benguela Ecosystem [PDF]

African Journal of Marine Science, 2003
The vertical distribution, abundance and size composition of a population of Pleurobrachia pileus was studied during a six-day drogue study conducted off the west coast of South Africa in February 1995. The population was centred in deep water, possibly because of the presence of a potential predator, Beroe sp., at shallower depths. The population of P.

Colloblasts act as a biomechanical sensor for suitable prey inPleurobrachia [PDF]

, 2020
AbstractCtenophores are a group of largely-planktonic, gelatinous carnivores whose most common method of prey capture is nearly a phylum-defining trait. Tentaculate ctenophores release an unknown proteinaceous adhesive from specialised colloblast cells lining their tentacles following prey contact with the tentacles.

Jellyfish and Ctenophores in Limfjorden (Denmark)—Mini-Review, with Recent New Observations

Journal of Marine Science and Engineering, 2014
Limfjorden is a major Danish water system that connects the North Sea via Thyborøn Kanal in the west and to the Kattegat in the east. Limfjorden is heavily eutrophicated and certain areas suffer from oxygen depletion each summer.
