If you’ve ever thought, “What if a shark was also a nightmare ribbon from the Cretaceous period?” then Chlamydoselachus anguineus is here to fulfill that oddly specific wish. Known as the frilled shark, this deep-sea relic has barely changed in 80 million years, sporting 300 trident-shaped teeth arranged in 25 rows—perfect for snagging squid and unsettling anyone who makes direct eye contact. Found as deep as 1,500 meters, it moves with an eerie, eel-like undulation that whispers, “I’m older than your evolutionary branch.” This hard enamel pin captures its prehistoric elegance in polished metal and bold enamel—no submersible required.

Specs:

• Premium metal base with polished hard enamel fill
• Secure clasp to keep your shark from “swimming off”
• Size: 55.5 x 31mm
• Zero threat to your local fish tank (or your fingers)

Perfect for marine biology nerds, deep-sea enthusiasts, or anyone who enjoys the rare combo of scientific accuracy and unsettling charm.
