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

Scientists at the NOAA Northeast Fisheries Science Center have developed an unusually rich picture of who is eating whom off the Northeastern United States. The findings, published recently in Fish and Fisheries, provide a close look at fish feeding habits for 17 fish species, predators, and their prey.

It seems like each day scientists report more dire consequences of climate change on animals and plants worldwide. Birds that are migrating later in the year can't find enough food. Plants are flowering before their insect pollinators hatch. Prey species have less stamina to escape predators. In short, climatic shifts that affect one organism are likely to trigger ripple effects that can disturb the structure and functioning of entire ecosystems.

Streams in areas converted to oil palm have different top predators to those flowing through intact forests, affecting stream food webs.
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 […]
