A shark's tooth from a tourist shop is not an obvious subject for a poem, and Dave Bonta's opening question admits as much: "From what tacky tourist trap did it come?" The speaker doesn't even know where the object came from, only that "I think my grandparents brought it back" from a cruise. The poem begins with a shrug at the cheapness of the thing, then spends fifteen lines showing how much a small, doubtful object can hold. Its central idea is that a trinket's power lies less in what it is than in what a mind pours into it, and that the imagination, once it starts, may arrive somewhere unsettling.
The shift from deflation to wonder happens inside the first two lines. "Tourist trap" is sneering and flat, but the next phrase, "that ocean's arrowhead," is a real metaphor. It turns a souvenir into a weapon, something shaped by a hunter's hand, and the poem keeps climbing from there. The tooth is "a talisman luckier than a rabbit's foot / or a saint's ear." The saint's ear is a deliciously odd comparison. It draws on the old habit of treasuring body parts as relics, and it quietly reminds us that a tooth is a body part too. The comparison is half joke, half serious, and that mix of comedy and reverence runs through the whole poem.
Then comes the pivot: "It was not much bigger / than a mole's snout, but sharp, so sharp." The sentence breaks mid-line, and the repeated word gives the danger a little jolt. The sharpness stays in the poem and returns in the last line as "sharper than a shadow." From this one tooth the speaker's mind builds a whole mouth: "serried ranks, sierras." "Serried" means packed in tight rows, and the sound of the word is itself a row of s's. "Sierra," meaning both mountain range and, in Spanish, a saw, folds the jagged outline of peaks and the serration of teeth into a single word. Then the view widens again to "the circling fin, evil twin of the sail." The phrase suggests a sailing ship's twin turned sinister. Since the tooth came back from a cruise, it may also hint that something menacing circled beneath the pleasure trip, though that is an inference, not something the poem says.
The tone stays casual throughout, partly through small choices. The ampersands in "one & only" and "& the circling fin" make the poem look jotted down, like a note to oneself. The hedges, "I think" and "I recall," admit that memory is shaky. The poem is unrhymed, and its lines hover around nine or ten syllables, close enough to a steady beat that the sentences feel conversational but not shapeless. The long final sentence, running across five lines with the interruption "—I recall—" in the middle, enacts the gradual closing-in of attention, as the speaker looks harder and harder at one small object.
That looking produces the poem's most interesting turn. The imagined sea monsters give way to a plain description of the real thing: "a kind of off-brown, / the color of moldy leather or dried blood." These are decayed, slightly repellent images, far from the glamour of the open ocean. Yet the tooth is "shiny enough to serve as a mirror," and what appears in it is "something not quite my reflection / but sharper than a shadow." The poem stops there, with no explanation. The judgment is open, but the phrasing suggests the speaker sees an edgier, more dangerous version of himself, or perhaps an early sense of mortality, since "dried blood" has already hinted at death. A shadow is a dull, flat copy of a body, so something "sharper" than that has more definition and more bite.
The poem is significant for how much it does with so little. It begins in mild embarrassment and ends in quiet strangeness, without once raising its voice. It shows that a childhood keepsake can work as a lens on how we imagine danger, and on how we first glimpse ourselves in it.
