The function of the heterocercal tail in sharks has long been debated in the literature. Previous kinematic data have supported the classical theory which proposes that the beating of the heterocercal caudal fin during steady horizontal locomotion pushes posteroventrally on the water, generating a reactive force directed anterodorsally and causing rotation around the center of mass. An alternat...

To understand the mechanisms of liver regeneration better to promote research examining liver diseases and marine biology, normal and regenerative liver tissues of Chiloscyllium plagiosum were harvested 0 h and 24 h after partial hepatectomy (PH) and used to isolate small RNAs for miRNA sequencing. In total, 91 known miRNAs and 166 putative candidate (PC) miRNAs were identified for the first ti...

Three new records of Tanacetum L., namely, T. punctatum and T. zahlbruckneri from Azerbaidjan and T. vulgare from Mazandaran Provinces are reported for the first time from Iran. Illustrations and distribution map are also presented for each species.

Bryophytes are terrestrial plants and they contain many important medical aspects. In this study, six different bryophytes (Polytrichastrum formosum, Plagiomnium cuspidatum, Hypnum jutlandicum, Sphagnum palustre, Rhizomnium punctatum Pellia epiphylla) were collected from Trabzon, Türkiye. The effect of the extract these on some human pathogenic microorganisms especially causing skin diseases (S...

This study investigated, for the first time, age and growth of spotted lanternfish Myctophum punctatum through an analysis otolith microstructure. A total 377 individuals were collected from Strait Messina (central Mediterranean Sea), ranging between 20.3 73.7 mm standard length. Their length–weight relationship was estimated, these outputs indicated isometric growth, all specimens when males f...

Development of the ability to capture prey is crucial to predator survival. Trends in food-capture performance over early ontogeny were quantified for leopard sharks Triakis semifasciata and whitespotted bamboosharks Chiloscyllium plagiosum by measuring suction pressure and flow in front of the mouth during feeding. At any size, C. plagiosum produce greater subambient pressure and ingest more r...

APSL (active peptide from shark liver) is a hepatic stimulator cytokine from the liver of Chiloscyllium. It can effectively protect islet cells and improve complications in mice with alloxan-induced diabetes. Here, we demonstrate that the APSL sequence is present in the N-terminus of novel TBC (Tre-2, Bub2 and Cdc16) domain family, member 15 (TBC1D15) from Chiloscyllium plagiosum. This shark TB...

Facultative automictic parthenogenesis has only recently been confirmed in the most ancient jawed vertebrates, the chondrichthyan fishes (sharks, batoids, and chimeras). To date, however, in both documented cases, the females have only produced a single parthenogen offspring, and none of these have lived for more than 3 days. We present a genetically verified case of automictic parthenogenesis ...
