To determine which characteristic is common to a starfish and a snail, you need to familiarize yourself with the traits of these two organisms. Let's break it down:
A. Echinoderms: Starfish belong to the phylum Echinodermata, but snails do not. Therefore, this is not the correct answer.
B. Mollusks: Snails belong to the phylum Mollusca, which includes various types of mollusks. Starfish, however, are not mollusks. Hence, this is not the correct answer.
C. Size: While starfish and snails can vary in size, there is no specific characteristic that makes their size the same. Therefore, this is not the correct answer.
D. Invertebrates: Both starfish and snails lack a vertebral column, making them both invertebrates. This means that their bodies do not contain a backbone. Therefore, D is the correct answer.
So, the characteristic common to both a starfish and a snail is that they are both invertebrates (D).
