Encyclopedia
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

Science
Invertebrate Zoology is the subdiscipline of Zoology that consists of the study of invertebrates, animals without a backbone (a structure which is found only in fish, amphibians, reptiles, birds and mammals). Invertebrates are a vast and very diverse group of animals that includes sponges, echinoderms, tunicates, numerous different phyla of worms, molluscs, arthropods and many additional phyla. Single-celled organisms or protists are usually not included within the same group as invertebrates. — Wikipedia

- Invisible fertility crisis: Chemicals and climate...on April 28, 2026 at 6:00 pm
The rise in infertility is not limited to humans, as environmental stressors are quietly undermining the reproductive potential of different forms of life. A recent review published in npj Emerging Contaminants investigated how today's environmental challenges are shaping the reproductive capacity of both humans and animals.
- From pet to pest: Research warns invasive...on April 28, 2026 at 4:40 pm
A new peer-reviewed study conducted by researchers at The University of Toledo and University of Missouri provides some of the first rigorous experimental evidence that goldfish—one of the world's most popular pets—can dramatically change freshwater ecosystems when released or they escape into the wild.
- Giant octopuses may have ruled the oceans 100...on April 23, 2026 at 10:30 pm
Today's octopuses are intelligent, remarkably flexible animals that lurk in reefs, hide in crevices, or drift through the deep sea. But new research suggests that their earliest relatives may have played a far more predatory role in ocean ecosystems. A study led by researchers at Hokkaido University has found that the earliest known octopuses were giant predators that hunted at the very top of the food web, alongside large marine vertebrates. The study is published in Science.

Florida's Indian River Lagoon has been an ecosystem in decline going back to 2011, when harmful algal blooms led to a severe decline in seagrass, the foundational component of shallow coastal ecosystems.
