Passage
Echinoderms are deﬁned as any of a variety of invertebrate marine animals characterized by a hard, spiny covering or skin. They have attracted much attention due to their extensive fossil record, ecological importance, and bizarre body forms. Most echinoderms are extinct, but many living representatives still exist. All living echinoderms have an internal skeleton and a central cavity, but the outward appearance can vary signiﬁcantly. For example, starﬁsh and brittle stars have arms that extend from a central disk; sea lilies have a central stalk, or stem, and resemble ﬂowers; sea cucumbers are wormlike and tend to burrow.
The ways in which echinoderms move and feed are as diverse as their body forms. Table 1 lists certain echinoderms and their methods of locomotion (movement) and feeding.

Table 2 includes examples of echinoderm habitats around the world.

Q. The echinoderm shown below is most likely a:

a)
sea lily.
b)
starﬁsh.
c)
sea cucumber.
d)
brittle star.

According to the passage, “sea cucumbers are wormlike and tend to burrow.” The echinoderm pictured most resembles a worm so it is likely a sea cucumber.

They are invertebrates, which means that they do not have a skeleton. To protect themselves, they will attach to ﬁrm objects on the sea ﬂoor, such as rock or coral.Sea anemones can alter their body shape according to changes in their environment. For example, when ocean currents are strong, the sea anemone will reduce its internal volume in order to decrease the surface area that is exposed to the current. Sea anemones are dependent on water ﬂow for food and nutrients and also for assistance in eliminating waste.Most anemones share a symbiotic relationship with marine algae called zooxanthellae. These are photosynthetic organisms whose waste products are a food source for the sea anemone. The sea anemone also enjoys a mutualistic relationship with the clown ﬁsh. This ﬁsh is immune to the stinging tentacles of the sea anemone, and it helps the anemone by actually cleaning the tentacles. The cleaning process yields food for the clown ﬁsh, while it remains protected from potential predators by the sea anemones stinging tentacles.Figure 1 shows a cross-section of portions of the internal anatomy of a sea anemone.Q.As shown in Figure 1, the part of the sea anemone’s anatomy that connects its mouth to its gastrovascular cavity is the
