Solution
The correct answers are:
- Non-cephalopod mollusk
- Arthropod
Explanation:
An open circulatory system is one in which blood is not entirely contained within blood vessels and flows freely in the body cavity. This type of circulatory system is common in invertebrates such as arthropods (which include insects, spiders, and crustaceans) and most mollusks (except cephalopods like squids and octopuses which have a closed circulatory system).
Chordates (which include vertebrates) and cnidarians (which include jellyfish and sea anemones) typically have a closed circulatory system, where blood is contained within blood vessels.
