Invertebrate : lacking a spinal column
also : of, relating to, or concerned with invertebrate animals — Webster
Invertebrate is an animal that neither possess nor develops a vertebral column (commonly known as a backbone or spine), derived from the notochord. This includes all animals apart from the subphylum Vertebrata. Familiar examples of invertebrates include insects; crabs, lobsters and their kin; snails, clams, octopuses and their kin; starfish, sea-urchins and their kin; jellyfish, and worms.
The majority of animal species are invertebrates. Many invertebrate taxa have a greater number and variety of species than the entire subphylum of Vertebrata. — Wikipedia

A worm's view on immunity
on September 25, 2020 at 1:12 pm
All higher organisms have an immune system that constitutes a biological defense mechanism to protect the body from pathogens and foreign substances. It consists of a complex network of different organs, cell types and molecules that recognizes and fights harmful substances and pathogenic microorganisms. Invertebrates rely exclusively on the innate immune system, which protects the integrity of the organism from pathogen attacks through various barriers and other defense mechanisms. The innate […]

To understand how climate change may affect different ecosystems, 27 researchers from Brazil, Argentina, Colombia, Costa Rica, French Guiana and Puerto Rico, among other countries, conducted experiments in seven different locations involving the aquatic environment in the tank (centrally-located water-holding cup) of bromeliads, a habitat for insect larvae and other small organisms.
Warming ocean, old-forest loss put a squeeze on...

Squeezed by changing ocean conditions that limit their food options and the long-term loss of old forest needed for nesting, marbled murrelets would benefit most from conservation efforts that take both ocean and forest into account, new research by Oregon State University shows.
