Turkish Journal of Bioscience and Collections, 2017 Humans have begun to make collections with many living and lifeless samples that they have collected from the very nature of the past as a result of day-to-day curiosity. Thanks to these collections, many living creatures are playing an important role in

Nitrogen excretion and oxygen consumption under severe hypoxia in siluriform fishes from the Amazon
Journal of Fish Biology, EarlyView.Abstract Siluriform fishes collected from the Rio Negro and Rio Solimões proved to be highly resistant to aquatic hypoxia. In all four species analysed in this study, aquatic oxygen consumption significantly decreased from normoxic levels at water PO2 values near 1 kPa. Air‐breathing activity was observed only in Sturisoma sp. (Rio Negro).

An overview of the postcranial osteology of caecilians (Gymnophiona, Lissamphibia)
The Anatomical Record, Volume 309, Issue 3, Page 674-699, March 2026.Abstract Caecilians comprise a relatively small (~220 species) group (Gymnophiona) of snake‐like or worm‐like, mostly tropical amphibians. Most adult caecilians are fossorial, although some species may live in aquatic or semi‐aquatic environments, either as larvae or adults.

Journal of Pineal Research, Volume 78, Issue 2, March 2026.ABSTRACT Circadian rhythm alignment depends on environmental light detection via opsins. Pinopsin, originally identified in the pineal organ of birds and later in amphibian pineal complex and eyes, may play a role in this process, though its function has not been genetically tested.

Growth Pattern and Condition in the Mudskipper Scartelaos histophorus in the Mekong Delta
Ecology and Evolution, Volume 16, Issue 2, February 2026.Analysis of 1436 mudskippers (Scartelaos histophorus) from the Mekong Delta revealed consistently negative allometric growth. Growth exponents and condition factors were higher in females and during the dry season, emphasizing the roles of life‐history and hydrological drivers in estuarine adaptation. ABSTRACT Studies of the length–weight relationship (
