Origin of secretin receptor precedes the advent of tetrapoda: evidence on the separated origins of secretin and orexin. [PDF]
PLoS ONE, 2011 At present, secretin and its receptor have only been identified in mammals, and the origin of this ligand-receptor pair in early vertebrates is unclear.

Ecology and Evolution, Volume 16, Issue 4, April 2026.By analyzing 277 anuran mitochondrial genomes, this study reconstructs a robust phylogeny for frogs and toads, tracing their origins to the Triassic and major radiations to the Cretaceous‐Neogene. The research identifies 58 distinct gene arrangement patterns, providing a novel evolutionary framework.

The lungfish transcriptome: A glimpse into molecular evolution events at the transition from water to land [PDF]
, 2016 Lungfish and coelacanths are the only living sarcopterygian fish. The phylogenetic relationship of lungfish to the last common ancestor of tetrapods and their close morphological similarity to their fossil ancestors make this species uniquely interesting.

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 3, March 2026.ABSTRACT Artificial nesting structures were trialled to enhance reproductive habitat for endangered Mary River cod (Maccullochella mariensis) in Queensland, Australia. Twenty‐four hollow log structures of two designs were installed across six river sites and monitored alongside natural structures during the 2024 breeding season.

LUNGFISHES' BALANCING ACT [PDF]
Journal of Experimental Biology, 2007 ![Figure][1] Our bodies are constantly working to keep everything in balance; when we exercise, not only do we breathe harder to get more oxygen to our muscles, but also to get rid of the painful lactic acid `burn'. All air breathing land dwellers deal with acid – an excess of protons –

Functional Anatomy of the Hearts of Lungfishes and Amphibians [PDF]
American Zoologist, 1968 Lungfishes and amphibians have bimodal gas exchange, but various species employ airbreathing with lungs to different degrees. An increased use of pulmonary breathing is correlated with progressive structural and functional separation of the pulmonary and systemic vascular circuits.

The Anatomical Record, Volume 309, Issue 3, Page 550-602, March 2026.Abstract Actinopterygii is a major extant vertebrate group, but limited data are available for its earliest members. Here we investigate the morphology of Devonian actinopterygians, focusing on the lower jaw. We use X‐ray computed tomography (XCT) to provide comprehensive descriptions of the mandibles of 19 species, which span the whole of the Devonian

Lungfish dental pattern conserved for 360 Myr
, 2001 Lungfish, the closest living relatives of four-limbed animals, are unique in that adults lack marginal teeth and have to rely on palatal dental plates for crushing food.
