Finetooth Shark Jaw

Very nice jaw with near perfect dentition.  

The finetooth shark (Carcharhinus isodon) is a small, slender-bodied species known for its distinctive fine, needle-like teeth. It inhabits shallow coastal waters of the western Atlantic Ocean, ranging from North Carolina in the United States to Cuba and southern Brazil, including the Gulf of Mexico. sharksider.com+5floridamuseum.ufl.edu+5en.wikipedia.org+5

Physical Characteristics:

• Size: Males typically reach lengths between 1.5 to 2.3 meters (5 to 7.4 feet), while females average 1.8 to 2.3 meters (5.9 to 7.5 feet). The maximum recorded length is approximately 3.4 meters (11.1 feet). floridamuseum.ufl.edu
• Appearance: They exhibit a dark bluish-gray or bronze coloration on top, transitioning to white on the underside. Notably, their fins lack distinctive markings, and they possess a long, pointed snout with large eyes. floridamuseum.ufl.edu

Habitat and Behavior: Finetooth sharks are commonly found in shallow coastal areas, often near estuaries, lagoons, bays, and river mouths, favoring depths up to 10 meters (32.8 feet). They are social creatures, forming large schools that actively hunt small bony fishes such as menhaden and mullet, sometimes chasing them into the surf zone. coastal.msstate.edu+4floridamuseum.ufl.edu+4animalia.bio+4

Reproduction: This species is viviparous, meaning they give birth to live young. After a gestation period of approximately 12 months, females birth litters ranging from 1 to 13 pups, each measuring between 51 to 64 centimeters (20 to 25 inches). Birthing typically occurs from late May to mid-June, with females moving into nursery areas during this period. en.wikipedia.org+2floridamuseum.ufl.edu+2animalia.bio+2

Conservation Status: According to the International Union for Conservation of Nature (IUCN), finetooth sharks are currently classified as a species of Least Concern. Gillnet bans in states like Florida, Georgia, South Carolina, and Texas have contributed positively to their population stability. Additionally, they are managed under the U.S. Fisheries Management Plan for Atlantic tunas, swordfish, and sharks.
