Which of the following characteristics is unique to animals?   show

Which of the following characteristics is exhibited by most hydrozoans?   show

Which of the following statements describes how healthy corals appear brightly colored?   show
🗑
Which of the following animal groups is entirely aquatic?   show
🗑

🗑
Which phylum is characterized by animals that have a segmented body?   show
🗑
show filter feeding
