marine invertebrates

Marine invertebrates are animals that live in ocean environments and lack a backbone. They include diverse groups such as jellyfish, octopuses, sea urchins, and corals. These organisms play vital roles in marine ecosystems, contributing to food webs and maintaining habitat structures. They can be found in various shapes and sizes, from tiny plankton to large squid. Despite their lack of a spine, many have complex behaviors and adaptations. Marine invertebrates are crucial for human interests, supporting fisheries, tourism, and biomedical research. Understanding them helps us appreciate marine biodiversity and the health of our oceans.
