Clown fish are often found swimming within the tentacles of sea anemone whereas other fish avoid them at almost all cost. Which statement below is the best explanation for this observation? The spicules of the sea anemone cannot penetrate a slime layer surrounding a clown fish but other fish do that have that neutralizing slime layer. Clown fish are good at maneuvering between the spines of the sea anemone and use them for camouflage. Clown fish are attracted to the cnidocytes of the sea anemone as their source of food. Clown fish are immune to the sting of the nematocyst of the sea anemone but other fish are not.

Classification of Marine Organisms

Classification is a way of categorizing organisms that enables an easy process of identification of such organisms. All living things are classified by grouping them under specific categories. The grouping is done based on the close relativeness of the organisms. The classification tool requires knowledge of characteristics, differences, and similarities between different organisms.
