The fascinating animal kingdom creatures that dominate the ocean are great white sharks (Carcharodon carcharias). They are popular for the fear they instill and their imposing form. Over the years, American waters have been home to some of the largest great white sharks. Whether it’s the Pacific or Atlantic waters, these sharks provide an understanding of how these animals move, and their migratory and hunting patterns.
1. Deep Blue: The Titan of Guadalupe Island
Measuring a whopping 20 feet whilst still in the 4400-pound range, Deep Blue is one the largest great white sharks around the globe. The sharks are known to have a site near the shoreside of California in the American waters. She was captured near the waters of Mexico back in 2014 and has been a topic of interest for researchers due to the size and shape she possesses. Deep Blue’s sightings have offered crucial insights into the size potential and migration routes of mature females in the Pacific Ocean.
2. Haole Girl: Hawaii’s Giant Visitor
Haole Girl is another massive, great white shark that is comparable to Deep Blue in size, at nearly 20 feet long. First spotted near Oahu, Hawaii, in January 2019, she quickly gained attention due to her striking resemblance to Deep Blue. Her presence in Hawaii provided rare footage of great whites in Central Pacific waters, offering clues about the less-documented migratory behavior of sharks in this area. Haole Girl has sparked discussions on shark behavior in tropical climates, previously thought to be uncommon.
3. Breton: A Colossus of the Atlantic
Breton, a 13-foot-long and 1,437-pound male great white shark, was tagged by OCEARCH off Nova Scotia in September 2020. Since then, Breton has made his presence known by traveling along the East Coast of the United States, with pings recorded in Florida’s waters. His movements provide valuable data on male sharks in the Atlantic, particularly their feeding and breeding grounds. Breton’s size, although smaller than some of the giants, still classifies him as a remarkable predator in the region.
4. Ironbound: The 1,000-Mile Traveler
Weighing in at 996 pounds and measuring 12 feet in length, the male great white shark known as Ironbound was tagged in Nova Scotia in 2019 and has been on quite the journey ever since then. With more than 13,000 miles on its tracker, this predator shark shows how these species go far and wide in search of food and even breeding opportunities. Due to the presence of this shark along the U.S. East Coast, researchers now have a case study that contributes to determining the health and distribution of great white populations in the Atlantic Ocean.
5. Maple: The Gulf of Mexico Explorer
Once again her journey reports have shed light on long long-range distance female great white sharks travel. Covering a vast area from the Canadian waters to the Gulf of Mexico, Maple is an 11-foot and 1,200-pound female shark with aggressive behavior. She has contributed to climate studies, prey availability, and measuring water temperatures that aid in the behavior of sharks. Her presence in the Gulf is evidence that American waters offer a strong diversity of habitats to great white sharks.
6. Scot: The Gulf Coast Giant
Scot, a 12-foot, 1,600-pound adult male, was first tagged in 2021 off Nova Scotia. He has since ventured down to the Gulf of Mexico, showcasing the expansive range of great white sharks in North American waters. Scot’s tracking data reveals that the Gulf is not only a migratory corridor but also an important habitat for sharks during the winter months, where water temperatures are favorable.
7. Mahone: North Carolina’s Apex Predator
One more giant tracked by OCEARCH is Mahone. He weighs 1,700 pounds and is over 13 feet long, and this male great white shark is often seen off the coast of North Carolina. His size and frequent presence in these waters have led to some questioning as to why great whites are present along the southeastern U.S. coast. Apparently, it’s for feeding and breeding purposes. Mahone’s data supports ongoing studies on shark density in these critical habitats.
8. Nukumi: The “Queen of the Ocean”
Nukumi has been nicknamed “Queen of the Ocean” and is one of the longest sharks. She is one of the largest female great whites ever recorded in the Atlantic measuring a length of 17 feet with a weight of over 3,500 pounds. OCEARCH, in the year 2020 in the waters of Nova Scotia tagged Nukumi and since then her movement along the East Coast has been closely monitored. What makes her special is that she is an elder female and thus her size and age provide a rare opportunity to study the lifespan and breeding characteristics of great whites.
Cape Cod: The Shark Capital of America
With Cape Cod boasting over 800 Great White sharks located in its waters, it has become apparent why this area is regarded as a popular fishing destination within the US. This Great White shark density can be linked to an abundance of seal populations that serve as an essential food source for these predators. Researchers are now able to frequently record large-sized sharks in this area, cementing why it is a vital spot for shark conservation efforts as well as public safety research.
Monterey Bay: A Pacific Predator Haven
In California, Monterey Bay is known to have been extremely rich in wildlife. This highlights why it caught the attention of great white sharks, as this abundance continues to this day. Occasionally, enormous sizes of predators are found within close proximity to this area as seals and sea lions that reside in nutrient-dense waters help attract these fish. The presence of great whites in Monterey Bay highlights the ecological balance between predator and prey in Pacific waters.
Long Island Sound: A Shark Comeback Story
Great white sightings are becoming increasingly common in the Long Island Sound, reflecting improved water quality and a rebounding ecosystem. While the area is more commonly known for smaller sharks, occasional great whites signal the potential for broader habitat use as marine life in the region recovers.
Shark Migration: A Coastal Odyssey
The vast migrations of many great white sharks in the waters of the United States are seasonal and in some cases, extend for an average of thousands of miles. The reasons for their migration are the existence of prey, temperatures, and breeding. Measures such as tracking and mapping are necessary to understand the population of sharks and the ways to protect them. Notable examples include Breton and Scot, whose journeys reveal the vast range of these apex predators.
Conservation Efforts: Protecting the Giants
The need to save Great Whites today is dire. OCEARCH and other organizations fulfill their important role in studies by leading tagging and tracking programs that monitor shark activity. Researching the factors that determine their threats, scientists try to conserve these apex predators as they are essential to the balance of marine ecosystems.
