Arthur’s Field Note: The quiet custodian of the coral—the Nurse Shark prefers peace over pursuit. You’ll find this gentle bottom-dweller resting beneath ledges or gliding slowly across sandy shallows, unbothered by the bustle above.
Details: • Species: Nurse Shark (Ginglymostoma cirratum) • Region: Gulf of Mexico / Caribbean • Era/Focus: Modern species; fossil tooth ID • Tooth ID: Broad crown with multiple fine ridges, almost fan-shaped; teeth arranged in neat overlapping rows for crushing crustaceans • Fun Fact: Nurse sharks are nocturnal nap enthusiasts—often found stacked together like sleepy submarines. Their name likely comes from the sucking sound they make when hunting, like a nursing calf.
Calm, patient, and unexpectedly strong—collect this card to honor the quiet power of the reef.
