Passage Excerpt from The Highest Tide
Excerpt from The Highest Tide
by Jim Lynch
The narrator’s summer job is collecting marine specimens in Puget Sound, Washington. In this excerpt, he is looking for specimens in the mudflats before daybreak. Mudflats, or flats, are coastal landforms created when sediment and silt from tides are deposited as the tides recede.
I rounded the oyster beds, to the far side. . . . It was low tide by then, and I saw the water hesitating at its apex, neither leaving nor returning, patiently waiting for the gravitational gears to shift. Dozens of anxious clams started squirting in unison like they did whenever vibrating grains of sand warned them predators were approaching. I stopped and waited with them, to actually see the moment when the tide started returning with its invisible buffet of plankton for the clams, oysters, mussels and other filter feeders. It was right then, ankle deep in the Sound, feet numbing, eyes relaxed, that I saw the nudibranch.1
In all my time on the flats I’d never seen one before. I’d read about them, sure. I’d handled them at aquariums but never in the wild, and I’d never even seen a photo of one this stunning. It was just three inches long but with dozens of fluorescent, orange-tipped hornlike plumes jutting from the back of its see-through body that appeared to be lit from within.
Nudibranchs are often called the butterflies of the sea, but even that understates their dazzle. Almost everything else in the northern Pacific is dressed to blend with pale surroundings. Nudibranchs don’t bother, in part because they taste so lousy they don’t need camouflage to survive. But also, I decided right then, because their beauty is so startling it earns them a free pass, the same way everyday life brakes for peacocks, parade floats. . . .
The dark mudflats loomed like wet, flattened dunes stretching deep into Skookumchuck Bay in front of our house. From a distance, they looked too barren to support sea life. Up close, they still did, unless you knew where to find the hearty clams, worms and tiny creatures that flourish in mud. . . . I’m not sure why I decided to take a look. It was still an hour before sunrise, and I knew exactly what the bars2 looked like in the moonlight, but for some reason, I couldn’t resist.
I heard it long before I saw it. It was an exhale, a release of sorts, and I instantly wondered if a whale was stranded again. We had a young minke3 stuck out there two summers prior, and it made similar noises until the tide rose high enough for rescuers to help free it. . . . I looked for a hulking silhouette but couldn’t find one. I waited, but there were no more sounds. Still, I went toward what I thought I’d heard, avoiding stepping into the mud until I had to. I knew the flats well enough to know I could get stuck just about anywhere. The general rule was you didn’t venture out past the shells and gravel with an incoming tide. I sank up to my knees twice, and numbing water filled my boots.
. . . I kept stepping toward the one sound I’d heard, a growing part of me hoping I’d find nothing at all. When I stopped to rest and yank up my socks, my headlamp crossed it. My first thought? A giant octopus.
Puget Sound has some of the biggest octopi in the world. They often balloon to a hundred pounds. Even the great Jacques Cousteau4 himself came to study them. But when I saw the long tubular shape of its upper body and the tangle of tentacles below it, I knew it was more than an octopus. I came closer, within fifty feet, close enough to see its large cylindrical siphon5 quiver. I couldn’t tell if it was making any sounds at that point, because it was impossible to hear anything over the blood in my ears. . . .
The creature’s body came to a triangular point above narrow fins that lay flat on the mud like wings, but it was hard to be sure exactly where it all began or ended, or how long its tentacles truly were, because I was afraid to pry my eyes off its jumble of arms for more than half a second. I didn’t know whether I was within reach, and its arms were as big around as my ankle and lined with suckers the size of half-dollars. If they even twitched I would have run. So, I was looking at it and not looking at it while my heart spangled my vision. I saw fragments, pieces, and tried to fuse them in my mind but couldn’t be certain of the whole. I knew what it had to be, but I wouldn’t allow myself to even think the two words. Then I gradually realized the dark shiny disc in the middle of the rubbery mass was too perfectly round to be mud or a reflection.
It was too late to smother my scream. Its eye was the size of a hubcap.6

Question
In paragraph 3, the phrase “the butterflies of the sea” conveys the idea that
- Anudibranchs do not have to work as hard as other animals to survive in the ocean.
- Bnudibranchs have colorful features that make them stand out.
- Cnudibranchs are delicate and have trouble adapting to their environment.
- Dnudibranchs are rare and difficult to find in the ocean.
Show the answer
Correct answer: B
The question asks what idea the phrase “the butterflies of the sea” in paragraph 3 conveys.
A. Incorrect. While the narrator does say that they “taste so lousy they don’t need camouflage to survive” (paragraph 3), the phrase explains that their bright appearance poses no threat to their lives.
B. CORRECT. The narrator describes the vibrant colors of the nudibranch in paragraph 2. Then in paragraph 3, the narrator says that “their beauty is so startling.” The nudibranchs are colorful and unique, just as many butterflies are.
C. Incorrect. The narrator describes the distinct appearance of the nudibranch but does not suggest that nudibranchs struggle to adapt to their environment because of this trait.
D. Incorrect. In paragraph 2, the narrator states, “I’d handled them at aquariums but never in the wild, and I’d never even seen a photo of one this stunning.” Although this suggests that the narrator has rarely encountered a nudibranch in the wild, it does not suggest that they are rare in the wild in general.
Question analysis
This figurative-language question asks what the phrase “the butterflies of the sea” conveys about nudibranchs, the sea slugs the narrator spots on a Puget Sound mudflat in an excerpt from the novel The Highest Tide. Students must use the description around the phrase to decide which quality of butterflies the comparison points to.

Why it is hard, traps and wrong answers (shows the answer)
Why it is hard
The nickname is explained in the same sentence, where the narrator says even it “understates their dazzle”, so the question is mostly a matter of reading on a few words. The trap is reading on too far: the next sentences explain why nudibranchs can afford to be showy, a different point. Students who bring their own idea of butterflies as fragile, or who turn the narrator's first sighting into rarity, drift away from what he stresses.
Figurative or literary language moderate Understanding the question
The comparison's point is supplied by the clause right after it, “even that understates their dazzle”, and by paragraph 2's fluorescent, orange-tipped plumes, not by anything butterflies are usually known for. (Graesser, Singer & Trabasso, 1994; Kintsch, 1998)
An unfamiliar subject minor Understanding the question
Few students have seen a nudibranch, footnoted only as a type of sea slug, so the picture of it must be built entirely from paragraph 2's description. (Recht & Leslie, 1988; Kintsch, 1998)
Strategy: Read the phrase with the sentence it sits in and the description of the nudibranch just before it, then decide which quality of butterflies the comparison is pointing to.
Traps
- True but not the answer: A choice says something accurate about the text that does not answer this question.
- Outside knowledge: A choice is plausible in the real world but not supported by this text.
- Reads too much in: A reasonable-sounding conclusion that goes further than the text allows.
The wrong answers, classified
A True but not the answer (King et al., 2004; Embretson & Wetzel, 1987)
Draws on the next sentences, which say nudibranchs taste too lousy to need camouflage, a real point about their survival but not what the butterfly comparison conveys.
C Outside knowledge (King et al., 2004; Recht & Leslie, 1988)
Brings in the familiar idea that butterflies are delicate, which the passage never uses; nothing suggests nudibranchs struggle to adapt, and the comparison is about their dazzle.
D Reads too much in (Graesser, Singer & Trabasso, 1994)
Turns the narrator never having seen one in the wild into a claim that nudibranchs are rare, which reflects his experience, not the meaning of the nickname.
Working it out, step by step
Spot the comparison
This asks about figurative language, words that compare two things to make a point. In paragraph 3, nudibranchs are called “the butterflies of the sea.” You need to decide which quality of butterflies the comparison points to.
Read the rest of the sentence
The sentence goes on: “but even that understates their dazzle.” To understate means to say less than the full truth. Dazzle means bright, eye-catching beauty. So the narrator means nudibranchs are even more dazzling than butterflies.
Look back at paragraph 2
Paragraph 2 describes the one he found. It had “dozens of fluorescent, orange-tipped hornlike plumes.” Fluorescent means glowing with bright color. Plumes are feathery tufts. Its body even seemed “to be lit from within.” Like a butterfly, it is bright and colorful, and it stands out.
Check each choice
- B fits: “colorful features that make them stand out” matches the glowing plumes and the dazzle.
- A is wrong because their bad taste explains how they survive, not what the butterfly phrase means.
- C is wrong because the passage never says nudibranchs are delicate or struggle to fit in.
- D is wrong because the narrator never seeing one in the wild is his own experience, not proof they are rare.
Watch out: A uses real details from the same paragraph. But they answer a different question: why nudibranchs can afford to be showy.
Choose the answer
The butterfly comparison points to the nudibranch’s bright, eye-catching colors. So the answer is B.
Why this answer and not the closest wrong one
A comes closest, since the same paragraph says nudibranchs “don’t need camouflage to survive.” But that explains why they can afford to be bright. The butterfly phrase itself is about their beauty, which even the nickname “understates.” B names that beauty: colorful features that stand out.
