The shortfin mako, Isurus oxyrinchus, is the fastest shark in the ocean and the closest living relative to the great white. The two species share the Lamnidae family and the body plan that supports endothermy and high-speed pelagic predation. The teeth, however, are distinct, and a collector who understands mako dentition can identify the species at a glance.
Anatomy
Mako teeth are narrow, smooth, and curved. There are no serrations — the cutting edges are smooth, designed for piercing and grasping rather than the saw-and-tear function of the great white. The crown is tall and slender; in upper anterior positions it sweeps backward in a graceful curve. Lateral teeth become more recurved and asymmetrical.
Size
Mako teeth typically range from 0.75 inches to 1.5 inches in slant height. Specimens above 1.5 inches come from very large adult animals and are uncommon in the market. The smaller size relative to great whites reflects the smaller average body size of the species and a more lightly-built skull.
Color
Modern mako enamel is a pale ivory, often very white, with a tan to gray root. The contrast between crown and root is typically more pronounced in mako than in great white. Pre-ban mako specimens carry a similar warm patina from long display, though the mako market never had the same trophy intensity as the great white market and pre-ban mako material is less prominent in the collecting world.
Sourcing
The shortfin mako is not currently subject to the same level of regulatory restriction as the great white in U.S. waters. Modern mako teeth enter the market primarily through commercial fisheries bycatch and limited recreational landings under federal management. The trade is open and the supply is relatively steady, which keeps prices accessible.
Pricing
A grade-A modern mako tooth in the 1.0 to 1.25 inch range typically prices in the $80 to $200 range. Pendants set in sterling silver or gold add the cost of the setting, typically pushing finished pendants to $150 to $400. Larger specimens above 1.5 inches in slant height move into the low hundreds.
Pendant Settings
The slender shape of mako teeth makes them well-suited to pendant work. The most common settings are sterling silver prong, sterling silver wire wrap, and 14k gold prong. A well-set mako pendant on an 18-inch sterling chain is a discreet and durable piece of natural-history jewelry.
Fossil Mako Ancestors
The mako lineage extends well into the fossil record. Isurus hastalis (sometimes considered Cosmopolitodus hastalis), the unserrated ancestor of the modern great white, produced teeth that look like oversized mako teeth and are sometimes called “false makos” in the trade. These are popular fossil specimens, particularly from Bone Valley and Sharktooth Hill in California.
What a Mako Tooth Represents
In a collection that includes great white material, mako sits as the lighter, faster cousin. The contrast between the broad serrated great white tooth and the slim smooth mako tooth tells a clean story about evolutionary specialization within one shark family. For a collector building thematic depth, mako is an essential parallel.
