Ctenophore Relationships and Their Placement As the Sister Group to All Other Animals
ARTICLES DOI: 10.1038/s41559-017-0331-3 Ctenophore relationships and their placement as the sister group to all other animals Nathan V. Whelan 1,2*, Kevin M. Kocot3, Tatiana P. Moroz4, Krishanu Mukherjee4, Peter Williams4, Gustav Paulay5, Leonid L. Moroz 4,6* and Kenneth M. Halanych 1* Ctenophora, comprising approximately 200 described species, is an important lineage for understanding metazoan evolution and is of great ecological and economic importance. Ctenophore diversity includes species with unique colloblasts used for prey capture, smooth and striated muscles, benthic and pelagic lifestyles, and locomotion with ciliated paddles or muscular propul- sion. However, the ancestral states of traits are debated and relationships among many lineages are unresolved. Here, using 27 newly sequenced ctenophore transcriptomes, publicly available data and methods to control systematic error, we establish the placement of Ctenophora as the sister group to all other animals and refine the phylogenetic relationships within ctenophores. Molecular clock analyses suggest modern ctenophore diversity originated approximately 350 million years ago ± 88 million years, conflicting with previous hypotheses, which suggest it originated approximately 65 million years ago. We recover Euplokamis dunlapae—a species with striated muscles—as the sister lineage to other sampled ctenophores. Ancestral state reconstruction shows that the most recent common ancestor of extant ctenophores was pelagic, possessed tentacles, was bio- luminescent and did not have separate sexes. Our results imply at least two transitions from a pelagic to benthic lifestyle within Ctenophora, suggesting that such transitions were more common in animal diversification than previously thought. tenophores, or comb jellies, have successfully colonized from species across most of the known phylogenetic diversity of nearly every marine environment and can be key species in Ctenophora. -
NEW RECORD of PLEUROBRACHIA PILEUS (O. F. MÜLLER, 1776) (CTENOPHORA, CYDIPPIDA) from CORAL REEF, IRAQI MARINE WATERS Hanaa

F. Müller, 1776) in the coral reef as was recently found in Iraqi marine waters. The specimens were collected from two sites, the first was in Khor Abdullah during May 2015, and the second site was located in the pelagic water of the coral reef area, near the Al-Basrah deep sea crude oil marine loading terminal. Three samples were collected at this site during May 2015, February and March 2018 which showed that P. pileus were present at a densities of 3.0, 2.2 and 0.55 ind./ m3 respectively. The species can affect on the abundance of other zooplankton community through predation. The results of examining the stomach contents revealed that they are important zooplanktivorous species; their diets comprised large number of zooplankton as well as egg and fish larvae. The calanoid copepods formed the highest percentage of the diet, reaching 47%, followed by cyclopoid copepods 30%, and then the fish larvae formed 20% of the diet. -
Phylum Ctenophora ( Comb Jellies Or Sea Walnuts) Characteristics, Classification, Examples
Phylum Ctenophora ( Comb Jellies or Sea Walnuts) Characteristics, classification, examples Ctenophores, or comb jellies, are the common names for animals in the Phylum Ctenophora. In American English, the name is pronounced with a silent "c", as "teen-o- four" or "ten-o-four". The preliminary "c" is pronounced in most European languages (as a syllable "ka"). Ctenophores are characterized by eight rows of cilia, which are used for locomotion. The cilia in each row are arranged to form a stack of combs, also called comb plates, or ctenes; thus the name ctenophore comes from the Greek, meaning "comb bearer". The more complete derivation, provided by H. Foundalis and T. Christopoulos, is that "ctena" means comb in ancient Greek (in Modern Greek, too: "ktena"), and "phora" is a morphological ending that comes from the Greek verb "pherein", to bear (Modern Greek: "phero"). Ctenophores are fairly simple animals that live only in marine waters; they can be found in most marine habitats, from polar to tropical, inshore to offshore, and from near the surface to the very deep ocean. There are probably about 100-150 species of ctenophores throughout the world's ocean, although most of these are poorly known. The best-known ctenophores are those that occur near-shore. Such species are typically planktonic, transparent and unpigmented, and most swim by synchronous beating of the eight rows of comb plates. Ctenophores are probably common members of the plankton in most coastal areas worldwide, although they have not been studied in many regions; ctenophores may be seasonally much more abundant in the spring and early summer. -

E-mail [email protected] 2University of Miami, Cox Center, 1301 Memorial Drive, Miami, Florida 33146, United States of America. E-mail [email protected] Abstract A new species of Glossocephalus, G. rebecae sp. nov., is described from deep-water in the Monterey Bay region of Cal- ifornia, Eastern Pacific Ocean. It seems to be associated exclusively with the mesopelagic ctenophore Bathocyroe fosteri. This association has been observed from 541–830 m depth. It is readily distinguished from G. milneedwardsi Bovallius, 1887 by the shape of the eye fields. The retina is organised into a crescent-shaped organ, occupying about one-quarter of the back half of the head, with the crystalline cones projecting both anteriorly and laterally. An updated review of the genus is provided, taking into account the new species, together with an overview of G. milneedwardsi, and three new records of associations with ctenophores for G. milneedwardsi. New observations on the interaction of G. milneedwardsi with one of its ctenophore hosts, Mnemiopsis sp., are also documented.

Running head: B. ABYSSICOLA PATTERNS OF PREDATION 1 Beroe abyssicola Patterns of Predation: A Behavioral Analysis Jacob L.

ABYSSICOLA PATTERNS OF PREDATION 2 Abstract Ctenophores play an important role in many marine ecosystems worldwide and affect multiple trophic levels. They consume large amounts of plankton while, in turn, are also consumed by fish. Beroe abyssicola is a carnivorous ctenophore that preys upon Bolinopsis infundibulum, a planktivorous carnivore. While many studies exist on the feeding behaviors of other ctenophore genera, research on the genus Beroe is lacking. This study aimed to discern the patterns of predatory behavior of B. abyssicola and found that size was a significant factor in feeding behavior. We also tested whether seawater conditioned with the chemical signature of B. infundibulum would cause a change in the behavior of B. abyssicola but found no significant effect. Lastly, we tested whether B. abyssicola would consume a species of Pleurobrachia but found no evidence for this. B. ABYSSICOLA PATTERNS OF PREDATION 3 Introduction Pelagic and nearshore trophic systems are highly variable both temporally and spatially. Within these environments, certain groups of organisms create limits on population size which, left unchecked, could shift the ecological balance (Kozloff 1990). One such animal is Bolinopsis infundibulum, a planktivorous ctenophore. This species goes through annual cycles of population growth followed by rapid decline, consuming large amounts of copepods in the interim (Båmstedt & Martinussen 2015). -
CTENOPHORA Comb Jellies
THREE Phylum CTENOPHORA comb jellies HERMES MIANZAN, ELLIOT W. Dawson, CLAUDIA E. MILLS tenophores have been described as the most beautiful, delicate, seem- ingly innocent yet most voracious, sinister and destructive of plankton Corganisms. They are exclusively marine, are found in all oceans at all depths, have many different shapes, and range in size from a few millimetres diameter to two metres long. They are mostly planktonic, but one order is bottom- dwelling with a creeping mode of existence. The planktonic forms are stunningly beautiful, diaphanous creatures, flashing iridescence as their comb-like cilia plates catch the light. Their bodies are soft, fragile, gelatinous. The phylum is small and well defined, with about 150 species worldwide (Mills 2008). Like the Cnidaria, they are radiate animals and at one time the two phyla were linked together as the Coelenterata. Ctenophoran symmetry is biradial and the general body plan somewhat more complicated than that of Cnidaria (Harbison & Madin 1982; Mills & Miller 1984; Harbison 1985). The two phyla are now thought to be only very distantly related. Recent evidence from ribosomal RNA sequencing shows that the Ctenophora lie close to the Porifera as the second-most-basic group of the Metazoa (Bridge et al. 1995; Collins 1998; Podar et al. 2001). Similarity in body form between pelagic ctenophores and medusae is a phenomenon of convergence. Ctenophores (literally, comb bearers) are named for their eight symmetrical tracks (comb rows) of fused ciliary plates (ctenes) on the body surface (Hernán- dez-Nicaise & Franc 1993). These constitute the locomotory apparatus that Leucothea sp. characterises the group. -
Coeloplana Waltoni, a New Species of Minute Benthic Ctenophore (Ctenophora: Platyctenida) from South Florida

Bayer (deceased). It is an ectosymbiont of octocorals in south Florida. Members of the ctenophoran order Platyctenida were unknown from American waters until 1945, when specimens from Miami, Florida were reported by F. G. Walton Smith and referred to the genus Coeloplana. That species subsequently was found in Jamaica, and Rankin (1956) described it under the new generic name Vallicula. A second species of creeping ctenophore was found in the 1960s and rediscovered in 2011, living as an ectosymbiont on octocorals in the coastal waters near Miami. This species belongs to the original genus Coeloplana and is here described as Coeloplana waltoni, new species. This description is based on specimens examined by F. M. Bayer in the 1960s and additional material from collections obtained in 2012–2013. Critical differences between C.
