Yes, since they are annelids, they are protostomes.
They are protostomes.
Most invertebrate animals are protostomes.
Bivalves are protostomes. They belong to the phylum Mollusca, which is characterized by protostome development. This means that during their embryonic development, the blastopore becomes the mouth.
Yes, molluscs fit into the group known as protostomes.
Yes, annelids belong to the protostome group of animals. Protostomes are a group of animals whose blastopore develops into the mouth first during embryonic development. Annelids, such as earthworms and leeches, exhibit characteristics consistent with protostome development.
Neither are protostomes. Chordates, Hemichordates, and Echinoderms are all deuterostomes (in that the blastopore forms the anus first). In protostomes, the blastopore forms the mouth first.
Deuterostomes. All chordates such as birds and mammals are deuterosomes.
Yes, squid are protostomes. They belong to the phylum Mollusca, which is part of the larger group called Ecdysozoa within the protostomes. In protostomes, the mouth develops from the blastopore during embryonic development, which is characteristic of squid and other mollusks.

Wings for powered flight have evolved multiple times in protostomes, with the best-known example being in insects. Other protostomes that have evolved wings for powered flight include some groups of arthropods, such as butterflies and dragonflies.
No, leeches are limbless.
