vertebrate : any of a subphylum (Vertebrata) of chordates that comprises animals (such as mammals, birds, reptiles, amphibians, and fishes) typically having a bony or cartilaginous spinal colum which replaces the notochord, a distinct head containing a brain which arises as an enlarged part of the nerve cord, and an internal usually bony skeleton and that includes some primitive forms (such as lampreys) in which the spinal column is absent and the notochord persists throughout life — Webster
Vertebrates comprise all species of animals within the subphylum Vertebrata (chordates with backbones). Vertebrates represent the overwhelming majority of the phylum Chordata. Vertebrates include the jawless fish and the jawed vertebrates, which include the cartilaginous fishes (sharks, rays, and ratfish) and the bony fishes.
Extant vertebrates range in size from the frog species Paedophryne amauensis, at as little as 7.7 mm (0.30 in), to the blue whale, at up to 33 m (108 ft). Vertebrates make up less than five percent of all described animal species; the rest are invertebrates, which lack vertebral columns. — Wikipedia

- Fossils of two Early Cretaceous species...on October 22, 2021 at 11:32 am
Two new species dating back to the Early Cretaceous Period were recently discovered in Sevier County in southwest Arkansas. One is a small skink researchers named Sciroseps pawhuskai and the other is a new fish named Anomoeodus caddoi.

While most people in the U.S. may think of bumble bees as the standard yellow and black variety, there are an estimated 260 bee species that sport about 400 different color patterns. One reason many people associate bumble bees with distinct colors is because evolution can influence multiple bee species to share similar color patterns in specific geographic regions, which scientists call mimicry.

Just as a professional athlete or concert pianist practices daily to hone and refine their physical movements for the best possible performance when it really counts, male zebra finches noodle around and sing slight variations of their courtship calls for most of their waking hours.
- Using laser-stimulated fluorescence to learn more...on October 19, 2021 at 2:00 pm
A small international team of researchers has used laser-stimulated fluorescence to learn more about how pterosaurs flew. In their paper published in Proceedings of the National Academy of Sciences, the group describes their study of the ancient flying reptiles aimed at learning more about their flight mechanics.

Nestled deep in the middle of the vertebrate brain is a multi-sensory integration and movement control center called the superior colliculus. In rodents, this brain region integrates multi-sensory inputs—visual cues, sounds, touch information, and smells—and delivers output signals to a variety of motor control centers in the brain, coordinating the animal's movements in response to its environment.
