Evolution of miniaturization and the phylogenetic position of Paedocypris, comprising the world's smallest vertebrate

It is concluded that the miniaturized cyprinids with remarkable morphological novelties, like Paedocypris and Danionella, are at the same time the most developmentally truncated taxa.

Paedocypris, a new genus of Southeast Asian cyprinid fish with a remarkable sexual dimorphism, comprises the world's smallest vertebrate

Paedocypris is a new genus of paedomorphic cyprinid fish from highly acidic blackwater peat swamps in Southeast Asia that includes two new species, one of which appears to be the smallest fish and vertebrate known, with the smallest mature female measuring a mere 7.9 mm.

Molecular phylogenetics and evolutionary diversification of labyrinth fishes (Perciformes: Anabantoidei).

This work reconstructed the first molecular-based phylogenetic hypothesis of anabantoid intrarelationships using both mitochondrial and nuclear nucleotide sequence data and concluded that brood care evolved three times independently from an ancestral free spawning condition without parental care.

Osteology of Paedocypris, a miniature and highly developmentally truncated fish (Teleostei: Ostariophysi: Cyprinidae)

The phylogenetic comparison to determine the systematic position of Paedocypris among cyprinids reveals that it shares not only a number of unique absences, but also highly unusual progressive characters with Sundadanio and Danionella, two other Asian miniature cypr inids, and hypothesize that the three genera form a monophyletic group.

Barcoding snakeheads (Teleostei, Channidae) revisited: Discovering greater species diversity and resolving perpetuated taxonomic confusions

Different species delimitation approaches the authors employed (BIN, GMYC, and PTP) were congruent in suggesting a potentially much higher species diversity within snakeheads than currently recognized, mostly due to either the incorporation of undescribed, narrow range, endemics from the Eastern Himalaya biodiversity hotspot or the incorporate of several widespread species characterized by deep genetic splits between geographically well-defined lineages.

Revision of the Family Badidae (Teleostei: Perciformes), with Description of a New Genus and Ten New Species

EVOLUTION OF MOUTHBROODING AND LIFE‐HISTORY CORRELATES IN THE FIGHTING FISH GENUS BETTA

The results thus challenge the general predictions of the “safe harbor” hypothesis for the evolution of alternative brood care forms in the fighting fish genus Betta and demonstrate that bubble nesters and mouthbrooders do not have a consistent set of life‐history correlates.

The myth of dorsal ribs in gnathostome vertebrates

It is demonstrated that putative dorsal ribs of polypterids have a unique ontogeny and represent an autapomorphy of this taxon, and that ribs of gnathostomes are ventral ribs.
