  author={Lynne R. Parenti},
Atherinomorphs have been recognized since 1964 as a group of teleost fishes comprising silvcrsidcs, phallostethids. killifishes, ricefishes, halfbeaks, needlefishes, flying fishes, and sauries. Atherinomorphs are diagnosed as monophyletic by derived characters of the testis, egg, reproductive behavior, circulatory system, ethmoid region of the skull, gill arches, pelvic girdle, jaw musculature, olfactory organ, and inferred reductions in the infraorbital series and some other bones. Monophyly… 

Eurypterygii caudal skeleton

The osteology of the caudal skeleton in representatives of 41 genera in 39 families of eurypterygian fishes was studied and it was found that in higher groups, there is a tendency for the elements to fuse together and to the centra and caUDal cartilage are lost due to lack of function.

The caudal skeleton of Batrachoidiformes (Teleostei: Percomorphacea): a study of morphological diversity, intraspecific variation, and phylogenetic inferences

The caudal-fin skeleton of 55 of the 82 species and 22 of the 23 genera of Batrachoidiformes is examined, emphasizing the detection of intraspecific variation to recognize morphological characters with phylogenetic significance.

Phylogeny of the Cyprinodontiformes (Teleostei, Atherinomorpha): the contribution of cranial soft tissue characters

Evidence for the usability of cranial soft tissue characters as a reliable additional source of information for cladistic studies of fish phylogeny is presented and a new hypothesis that agrees with the palaeogeographical framework of the break‐up of Gondwana is supported.

The evolution of pharyngognathy: a phylogenetic and functional appraisal of the pharyngeal jaw key innovation in labroid fishes and beyond.

This study provides a surprising, but well-supported, hypothesis for a convict-blenny sister group to the charismatic cichlids and new insights into the evolution of pharyngognathy.

The caudal skeleton of extant and fossil cyprinodontiform fishes (Teleostei: Atherinomorpha): comparative morphology and delimitation of phylogenetic characters

Some characters of the caudal skeleton in combination to other osteological features indicate the cyprinodontiform fossil genus †Prolebias to be a paraphyletic assemblage; †P.

A phylogenetic analysis and taxonomic revision of ricefishes, Oryzias and relatives (Beloniformes, Adrianichthyidae)

Ricefishes, known best by the model organism, the medaka, Oryzias latipes Temminck & Schlegel, 1846, comprise the family Adrianichthyidae, which ranges broadly throughout fresh and brackish waters of

The Infrabranchial Musculature and Its Bearing on the Phylogeny of Percomorph Fishes (Osteichthyes: Teleostei)

The present analysis further confirms the validity of infrabranchial musculature characters previously proposed to support the grouping of the Mugiliformes with the Atherinomorphae and the monophyly of the Labriforme with the possible inclusion of the Pholidichthyiformes.

Morphology of the jaw, suspensorial, and opercle musculature of Beloniformes and related species (Teleostei: Acanthopterygii), with a special reference to the m. adductor mandibulae complex

New anatomical descriptions of the jaw musculature in six selected beloniforms and four closely related species are presented and a reduction of the external jaw adductor and a changed morphology of the intramandibularMusculature were found in many Beloniformes.

†Kenyaichthyidae fam. nov. and †Kenyaichthys gen. nov. – First Record of a Fossil Aplocheiloid Killifish (Teleostei, Cyprinodontiformes)

Fossils from the upper Miocene Lukeino Formation in the Tugen Hills of the Central Rift Valley of Kenya represent the first fossil record of an aplocheiloid killifish and provide strong evidence for the assignment of the fossils to the Aplocheiloidei, and justify the definition of the new family †Kenyaichthyidae.

Gonad morphology, gametogenesis, and reproductive modes in fishes of the tribe Starksiini (Teleostei, Blenniiformes)

Although many of these features are seen in the internally fertilizing clinid blennies, starksiins differ in retaining the testicular gland typical of labrisomids and in lacking sperm packaging typical of other internal fertilizing teleosts.



Mechanisms of the jaws of some atheriniform fish

The anatomy and mechanisms of the jaws of these and of various other Atheriniformes have been studied and the terminology of the kinematics of machines is used in a general discussion of the mechanisms of teleost jaws.

The Cave, Spring, and Swamp Fishes of the Family Amblyopsidae of Central and Eastern United States

The study and remarks to the North American cave, spring, and swamp fishes belonging to the family Amblyopsidae are limited to the species and characteristics of the family.

Comparative morphology, seasonality, and a key to planktonic fish eggs from the Nova Scotian shelf

Seasonal variation was observed in egg sizes and adult sizes, with species attaining a large body size producing large eggs in colder months, while smaller species producing smaller eggs (usually with an oil globule) spawned in warmer months.

Enzyme clearing of alcian blue stained whole small vertebrates for demonstration of cartilage.

Alcohol treatment in addition to formalin fixation does not affect results with this method, it should be useful to researchers who want to study the cartilage or cartilaginous skeletons in museum specimens, which are routinely fixed in formalin and stored in alcohol.

Viviparity: The Maternal-Fetal Relationship in Fishes

The maternal-fetal trophic relationships in each of the major groups of fishes are systematically reviewed and Pertinent anatomical, histological, ultrastructural, developmental, physiological, and biochemical studies are considered.
