THE eleven families and nearly one hundred species of ceratioid anglerfish are distributed throughout the world's oceans below a depth of 500 m. The Ceratiidae, with two monotypic genera, Ceratias Kröyer and Cryptopsaras Gill, is one of four ceratioid families whose members exhibit a peculiar and unique mode of reproduction in which dwarfed males become permanently and parasitically attached to the body of a relatively gigantic female. Males of this family have large, forwardly directed eyes… 

Dimorphism, parasitism, and sex revisited: modes of reproduction among deep-sea ceratioid anglerfishes (Teleostei: Lophiiformes)

Additional evidence is provided to reaffirm the hypothesis that sexual parasitism has evolved separately at least three and perhaps five or more times within the deep-sea anglerfish suborder Ceratioidei.

Dimorphism, Parasitism and Sex: Reproductive Strategies among Deepsea Ceratioid Anglerfishes

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.

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 parasitism

Molecular systematics and life history evolution of anglerfishes ( Teleostei : Lophiiformes ) : Evidence from mitochondrial DNA

An mtDNA hypothesis for six deep-sea families provides preliminary evidence that sexual parasitism is not monophyletic and may have emerged rapidly in basal members of the suborder during ceratioid radiation, and a density-dependent model for the evolution of parasitism in ceratioids is presented.

Growth and reproduction in mesopelagic fishes: a literature synthesis

The current state of knowledge of research on age, growth, and reproduction of mesopelagic fishes, the basic biological information fundamental to understanding the population dynamics of species in this ecosystem are synthesized.

Challenges of Fish Diversity in Polluted Water

Fish species diversity is roughly divided equally between marine (oceanic) and freshwater ecosystems, whereas continental freshwater fishes are most diverse in large river basins of tropical rainforests, especially the Amazon, Congo and Mekong basins.

Linking local adaptation with the evolution of sex differences

This special issue synthesizes and extends emerging research at the interface between the research traditions of local adaptation and sex differences to generate new empirical predictions about the evolutionary consequences of selection that varies across space, time, and between the sexes.

An appreciation of the extent of the deep sea environment can be gained by considering one or two facts relating to that habitat . Water covers approximately 71% of the earth's surface with an

Taxonomy: Three into one will go

Striking instances of larval metamorphosis, and of adult sexual dimorphism, are not uncommon in the animal world. But especially dramatic examples of these phenomena have emerged from the deep sea.

A TEST OF THE CONJECTURE THAT G‐MATRICES ARE MORE STABLE THAN B‐MATRICES

A theoretical argument is presented that within‐sex G is more stable than between‐sex B, because they are more powerfully exposed to multivariate stabilizing selection and this conjecture was tested by comparing estimates of B‐ and within‐ sex G‐matrices among three populations of the garter snake Thamnophis elegans.
