(CN) — When it comes to survival, timing is everything — even for fish embryos. And according to researchers, these embryos aren’t just waiting around for the perfect moment to hatch. They’re actively ...

New research has revealed that fish embryos actively control their hatching timing through a neurohormone, Thyrotropin-Releasing Hormone (TRH), which triggers the release of enzymes that dissolve the ...

The annual killifish lives in regions with extreme drought. A research group now reports that the early embryogenesis of killifish diverges from that of other species. Unlike other fish, their body ...

Plastic contamination in freshwater ecosystems continues to rise, resulting in micro- and nanoparticle accumulation in the aquatic environment. A new study by an aquatic ecology group at the ...

Curtin University researchers have revealed how the pelvic fins of fish such as sharks and chimeras have evolved from their sudden appearance in the fossil record over 410 million years ago. The team ...

Zebrafish eggs contain a sunscreen called gadusol that protects the growing embryo from harmful rays. The ultraviolet rays in sunlight are damaging. To shield against this, vertebrates produce a ...

Plastic pollution in freshwater is increasing, leading to micro- and nanoplastic buildup. A study found these particles and their surface charge can harm fish reproduction, especially under stress.

How does a tiny cluster of cells become an embryo with a head, trunk, and tail? And how do thousands of genes coordinate this development? A new imaging method makes it possible to visualize the ...
