Spinifer

Spinifer refers to a genus of marine invertebrates belonging to the phylum Echinodermata. These animals are characterized by their distinctive spiny outer covering. They are commonly known as brittle stars or sometimes basket stars, though the term spinifer is more specific to the genus. Spinifer species are typically found in marine environments, inhabiting various depths from shallow waters to the deep sea. Their bodies are generally flattened and composed of a central disc from which multiple arms radiate. These arms are highly flexible and articulate, allowing for locomotion and prey capture.

The spines on the body of spinifer are a prominent feature, varying in size, shape, and arrangement depending on the species. These spines serve a protective function, deterring predators. The feeding mechanism of spinifer involves using their arms to sweep food particles from the water column or the seabed. They are detritivores or suspension feeders. Reproduction in spinifer, like other echinoderms, typically involves the release of gametes into the water column, leading to external fertilization and larval development. The larval stages are planktonic before settling to the seabed and metamorphosing into the adult form. Their ecological role often involves contributing to the benthic community and acting as a food source for other marine animals.
