  1. Why #vertebrate #eyes so different from those of other animals?
    A new hypothesis proposes that our ancestors lost their eyes, then rebuilt them.
    “Vertebrate eyes are so fundamentally different from the lateral eyes of other animal groups,” Dan-Eric Nilsson, expert in eye #evolution. “Hey difference is the identity of the main photoreceptor, which is of ciliary nature in the vertebrate eye but rhabdomeric in other animal groups, such as arthropods and cephalopods,” he adds

  6. " For fish and birds, this is described as gradual mouth gaping, staying open for at least three seconds and subsequently a rapid closure of the mouth. Almost all #vertebrate animals, including mammals, birds, reptiles, amphibians, and even fish, experience yawning. "

    Eyes, as light-sensing organs of the #lens #eye type, have #evolved independently multiple times in the animal kingdom. But what did a representative of the early #vertebrate lineage look like? According to G. Kafetzis et al. (2026), a worm-like #ancestor possessed #medianeyes bring #homologous to the modern #pinealgland of the #brain. Published in #CurrentBiology. #evolution

  12. #Eyes of the world's longest-living #vertebrate, the #GreenlandShark, show little #ageing
    Greenland #shark (Somniosus microcephalus) can live for up to 400 years in the chilly North Atlantic and Arctic waters, making it one of the longest-living #vertebrates on Earth. And according to new research its seemingly undead eyes are fully functioning and barely deteriorate even after a century. Unravelling the shark's anti-ageing secrets could benefit human eye health.

  17. 🐭🧠 The common #shrew is a tiny #vertebrate with a bizarre survival strategy called Dehnel’s phenomenon. To save #energy during lean #winter months, these #animals physically shrink their skulls and #brains, only to regrow them when #spring arrives.

  22. Not sure I should admit this, but in my family, loading dead animals into the car was totally normal. My dad always had a hatchet, saw, knives, and plastic bags in the trunk, and wouldn't hesitate to come to a full stop on a busy highway if he suspected the skull was undamaged. There was one on almost every shelf in the house. The car often smelled bad. #bones #vertebrate #skull
