Sexual parasitism, a remarkable mode of reproduction unique to some members of the deep-sea anglerfish suborder Ceratioidei, in which males are dwarfed and become permanently attached to much larger females, is described in a number of previously unreported specimens and taxa. Although generally attributed to all ceratioids, and despite more than a sevenfold increase in the number of known parasitized females in collections throughout the world in the past 50 years, the phenomenon is… Expand
Acquisition of Dwarf Male “Harems” by Recently Settled Females of Osedax roseus n. sp. (Siboglinidae; Annelida)
TLDR
A time-series analysis revealed the presence of a new species of Osedax, a genus of bone-eating siboglinid annelids, which is the fifth species described since the erection of this genus and, like its congeners, uses a ramifying network of “roots” to house symbiotic bacteria. Expand
Phylogenetic Relationships of Deep-sea Anglerfishes of the Suborder Ceratioidei (Teleostei: Lophiiformes) Based on Morphology
TLDR
Mapping modes of reproduction on the resulting trees reaffirmed the hypothesis that sexual parasitism has evolved independently more than once within the Ceratioidei suborder and perhaps as many as seven times. Expand
Sexual Parasitism in the Deep-sea Ceratioid Anglerfish Centrophryne spinulosa Regan and Trewavas (Lophiiformes: Centrophrynidae)
A sexually parasitized female of the deep-sea ceratioid anglerfish Centrophryne spinulosa is described for the first time, bringing the number of ceratioid species known to exhibit sexual parasitismExpand
Evolutionary history of anglerfishes (Teleostei: Lophiiformes): a mitogenomic perspective
TLDR
The acquisition of novel features, such as male dwarfism, bioluminescent lures, and unique reproductive modes allowed the deep-sea ceratioids to diversify rapidly in a largely unexploited, food-poor bathypelagic zone relative to the other lophiiforms occurring in shallow coastal areas. Expand
Miniature deep-sea hatchetfish (Teleostei: Stomiiformes) from the Miocene of Italy
TLDR
Anatomical and morphofunctional considerations suggest that Discosternon possibly was a midwater plankton feeder characterized by a reduced locomotory ability. Expand
Molecular Phylogeny of Echiuran Worms (Phylum: Annelida) Reveals Evolutionary Pattern of Feeding Mode and Sexual Dimorphism
TLDR
The results suggest that Echiura is monophyletic and comprises two unexpected groups: [Echiuridae+Urechidae+Thalassematidae] and [Bonelliidae+Ikedidae]; this grouping agrees with the presence/absence of marked sexual dimorphism involving dwarf males and the paired/non-paired configuration of the gonoducts (genital sacs). Expand
Genetic Diversity and Population Structure in Bryophyte With Facultative Nannandry
TLDR
The results show that DMs and NMs play different roles in reproduction, inbreeding may occur at cushion level, but gene flow is high enough to prevent substantial genetic drift. Expand
New records of Leptacanthichthys gracilispinis and Microlophichthys microlophus (Actinopterygii: Lophiiformes: Oneirodidae) from the subarctic Atlantic Ocean, including new lophiiform barcoding data and a rare observation of a copepod parasite in ceratioid anglerfishes
TLDR
Two new distributional records of ceratioid anglerfishes are presented and taxonomic issues based on molecular OTUs** are reported for the genera Caulophryne, Cryptopsaras, and Dolopichthys based on Cox1 data. Expand
Different on the inside: extreme swimbladder sexual dimorphism in the South Asian torrent minnows
TLDR
The male swimbladder is not only much larger than that of the female, but is also structurally more complex, with multiple internal septa dividing it into smaller chambers. Expand
New species and new records of deepsea anglerfish of the family Oneirodidae
TLDR
The described specimen differs from the previously known fishes in that thelength of its illicium is distinctly smaller than the length of its axonost (as opposed to the inverse relaa tionship in other specimens), although parameter ill falls within the limits of variability characteristic of this species.

Dimorphism, Parasitism and Sex: Reproductive Strategies among Deepsea Ceratioid Anglerfishes
TLDR
Data is presented to support at least three reproductive strategies utilized by ceratioid anglerfishes and it is suggested that a facultative sexual parasitism exists for some ceratioids, particularly some oneirodid genera, it would form a convenient evolutionary intermediate between those Ceratioids with obligatorySexual parasitism and those whose males never become parasitic.

Precocious sexual parasitism in the deep sea ceratioid anglerfish, Cryptopsaras couesi Gill
TLDR
This report describes sexual parasitism in surprisingly young females of C. couesi, and it is now evident that parasitic attachment can take place at an extremely early age immediately following metamorphosis. Expand
Dwarfed Males Parasitic on the Females in Oceanic Angler-Fishes (Pediculati Ceratioidea)
TLDR
I have found dwarfed males, parasitic on the females, in two genera of Ceratioid Fishes, and reasons are given for thinking that males of this type are characteristic of the group. Expand
On the Probable Identity, Life-History and Anatomy of the Free-Living and Attached Males of the Ceratioid Fishes
TLDR
The writer was led to suspect that the family in question might in reality represent merely the free-living stages of the males which have heretofore only been known to science through Mr. C. Tate Regan's amazing discoveries of various more or less degenerate specimens attached in a presumably parasitic fashion to the skin of the much larger females. Expand
