Brittle stars are not starfish; though both typically have five arms, they constitute different classes of echinoderms, the same invertebrate group that includes sea cucumbers (brittle stars and starfish do share a common ancestor, however).

Fossilized invertebrate embryos are rare, but when preserved, they offer key insights into the evolutionary developmental biology of extinct animals.

I always look at the stones at the bed of the river because I like looking for the invertebrate but I started to notice the stones were muggy.

Hannah Bird elaborated: "We used scanning and photography to make a 3-D digital model, allowing us to better visualise and identify the footprints and invertebrate traces.

In the meantime, as curator of invertebrate paleontology at the ROM, he is busy planning for a new gallery entitled Dawn of Life.

REHOVOT, Israel — For years, Israeli scientist Tamar Flash has been fascinated with the octopus, and the unusual way the invertebrate’s eight arms propel it effortlessly through the water.

Meanwhile the invertebrate population in Washington DC is exploding.

Caterpillars and pupae fall prey not only to birds, but also to invertebrate predators and small mammals, as well as fungi and bacteria.

Dinosaurs, extensive invertebrate and vertebrate collections, plant taxonomies, and so on - these were the orders of the day.

Endemism is also generally low and the invertebrate fauna is exceptionally pristine with few, if any, (successful) human-induced introductions of alien species.

Etymology The word "invertebrate" comes from the form of the Latin word vertebra, which means a joint in general, and sometimes specifically a joint from the spinal column of a vertebrate.
