Giant Turtle Hits Florida Boat, Gets Horse-Sized CT Scan

A startling collision off the coast of Florida left boaters shaken and one massive loggerhead sea turtle fighting for her life. Weighing in at 137 kilograms (302 pounds), this giant turtle was so large that rescuers had to wheel her into a CT machine designed for horses. What they discovered next took the story from bizarre to downright incredible.

A Collision That Could Have Been Catastrophic

The incident happened off Florida’s Atlantic coast—an area teeming with marine life but increasingly busy with boat traffic. A group of conservationists retrieved the injured giant turtle after it was hit by a passing boat. While the collision wasn’t fatal, the turtle showed signs of internal trauma.

This was no ordinary rescue. The giant turtle, later nicknamed Pennywise, was far too large for standard veterinary or even human CT scanners.

Once Pennywise arrived at the Loggerhead Marinelife Center, veterinarians knew she needed imaging to understand the full extent of her injuries. But nothing in-house could handle her size.

  • Massive proportions: At 137 kg (302 lb), she was too heavy for conventional medical machines.
  • Spinal concerns: The team suspected spinal or internal injuries from the boat strike, which could affect her ability to swim and dive.
  • Unlikely solution: She was transported to the Palm Beach Equine Clinic, where a horse-sized CT scanner—normally used for racehorses—was available.
  • Unexpected discovery: Not only did the scan confirm trauma near her spine, it also revealed that Pennywise was gravid, carrying viable eggs.

Why This Matters for Loggerheads

Loggerhead sea turtles are classified as threatened under the Endangered Species Act. Females like Pennywise are essential to keeping the species alive, especially because few of their hatchlings survive to adulthood.

  • Every female counts: Loggerheads can lay hundreds of eggs per season, but survival rates for hatchlings are less than 1 in 1,000.
  • Nesting season danger: Boat strikes increase during nesting months when females migrate to and from beaches.
  • Delayed reproduction: Loggerheads don’t reach maturity until around 30 years of age, making every reproductive turtle invaluable.

Boat Strikes Are on the Rise

Experts say sea turtle collisions with boats are becoming more common in Florida’s busy coastal waters. The rise in recreational boating, combined with turtles’ slow surface swimming, creates a risky mix.

  • High-speed zones: Even low-profile boats can cause lethal injuries if traveling at high speeds.
  • Unseen victims: Many turtles die without ever being found, meaning data underrepresents the scale of the problem.
  • Human impact: Boating, pollution, and habitat loss are converging to pressure sea turtle populations from all sides.

What Boaters Can Do to Help

This incident serves as a call to action for anyone taking to the water, especially during turtle nesting season (March through October in Florida).

  • Slow down: Reducing speed in known turtle zones gives both boaters and turtles time to react.
  • Watch for signs: Look out for turtle surfacing activity, especially near nesting beaches and reefs.
  • Avoid known turtle routes: Stay outside designated conservation zones whenever possible.
  • Report any collisions: Alert local wildlife officials immediately so injured turtles can be rescued and treated.

A Shell-Shocking Survival Story

Pennywise’s story could have ended with a silent death beneath the waves. Instead, it’s become a symbol of resilience, science, and quick action. Thanks to a repurposed horse CT scanner, skilled veterinarians, and a bit of marine luck, she now has a shot at returning to the ocean—and laying the next generation of giants.

Let her story be more than a one-off rescue. Let it be a reminder that even our leisure can have weighty consequences, and that sometimes, saving one giant turtle can ripple through an entire species.
