Yes, they are invertebrates.
Yes, Annelids are invertebrate animals .
3 of the water invertebrate groups are the annelids, arthropods and crustacean.
They are invertebrates.
The eight groups are:* Mollusks * Echinoderms * Arthropods * Annelids * Nematodes * Porifera* Platyhelminthes * Coelenterates Or go to:What_are_the_8_groups_of_invertebrates
Protonephridia are primarily associated with the class Turbellaria, which includes free-living flatworms, rather than annelids. However, in the context of annelids, the class Oligochaeta (such as earthworms) and the class Hirudinea (leeches) have a different excretory system involving nephridia, which are more complex than protonephridia. In summary, protonephridia are not characteristic of annelids but rather of certain other invertebrate groups.
Porifera (Sponges)Cnidaria (Coelenterates)Flatworms (Platyhelmenthes)Roundworms (Aschelmenthes - Nematode)Segmented worms (Annelids)Mollusks (Soft-Bodied/ hard shelled Animals)Echinoderms (Spiny-Skinned Animals)Arthropods
An Invertebrate is a creature with no back bone. The most common invertebrates include protozoa, annelids, echinoderms, mollusks and arthropods. Example of invertebrates: worms, snails, starfish, spiders and crabs.
One trend that did not occur during invertebrate evolution is the development of true segmentation in all invertebrate lineages. While segmentation is a prominent feature in some groups, such as annelids and arthropods, many invertebrates, including cnidarians and mollusks, do not exhibit this characteristic. Instead, invertebrate evolution is marked by a diversity of body plans and organizational structures, with some lineages remaining unsegmented throughout their evolutionary history.
no. they are in a group of creatures called "annelids".
