Deep-sea fish reveal an alternative developmental trajectory for vertebrate vision Hybrid photoreceptors in larval deep-sea fish reveal evolution of an alternative developmental trajectory for vertebrate vision.

A new #ScienceAdvances study finds three deep-sea fishes see light unlike any other vertebrates, thanks to hybrid retinal cells. https://scim.ag/3Oo1dmx

Table coral

Three-way hybridization of table corals in the Acropora hyacinthus group from the southern Great Barrier Reef results in parallel adaptive introgression. Check out our new preprint: doi.org/10.64898/202...

Deep-sea fish larvae rewrite the rules of how eyes can be built Deep-sea fish larvae combine features of both rods and cones into a single, highly specialised cell that is optimised for life in between light and darkness.

CrossFilt: A Cross-species Filtering Tool that Eliminates Alignment Bias in Comparative Genomics Studies Comparative functional genomic studies are often affected by biased read mapping across species due to inter-species differences in genome structure, sequence composition, and annotation quality. We d...

We developed CrossFilt, a read-level, cross-species filtering approach that avoids these errors without sacrificing usable data. It outperforms all existing strategies and exposes just how much signal in comparative genomics has been misread.

3/3 Once the larvae have hatched they enter a 10-14 day pelagic phase where they need to feed like crazy on various types of zooplankton (copepods, rotifers and brine shrimps in the lab) before they return to the reef, or in our case the pot, to settle and metamorphose into a mini #nemo

2/n Once the eggs have been successfully fertilised, they will turn black after 2-3 days as the embryos begin to develop their black pigment in the skin.

After ~8-10 d the eyes start silvering up and the embryos will hatch shortly thereafter, this usually occurs at night. See next post for larvae

1/n Amphiprion percula aka #nemo ready to spawn. This is one of our most proficient breeding pairs in the University of Queensland breeding colony. The female will adhere her eggs to the pot for the male to fertilise —> see next post

A standardized nomenclature for the rods and cones of the vertebrate retina Vertebrate photoreceptors have been studied for well over a century, but a fixed nomenclature for referring to orthologous cell types across species has been lacking. In this Consensus View, the autho...
