A great white shark Caught in the Mediterranean has continued a long scientific investigation into a population many thought extinct. An unusual encounter, reported off the coast of Spain, has forced researchers to reassess more than 160 years of evidence.
For example, height of about 210 cm and weight between 80 and 90 kgit was caught by local fishermen on April 20, 2023. Sightings in this part of the Mediterranean are still rare, which makes every confirmed report especially important to scientists tracking the species.
In order to understand whether this event was selected or part of a wider pattern, researchers turned to historical documents. By collecting the latest reports on 19th centurythey intended to clarify whether great white sharks still exist in these waters.
A long history points to a hidden presence
A team of researchers collected recorded and captured sightings since 1862, to create a detailed timeline of the species in the Mediterranean. According to research published in Journal of Ichthyology and Fisheriesthe data reveal a consistent, if unusual, pattern.
Rather than disappearing, the species appears to persist with very low levels of detection. Scientists refer to this as a “ghost member,” a group that is always present but seldom noticed. Gaps in sightings, sometimes lasting for years, have contributed to the belief that the species has disappeared from the region.
These unusual reports show the difficulty of monitoring marine predators and the wider behavior of Carcharodon carcharias. The Mediterranean shows no signs of a dense population, yet the accumulated evidence confirms continuity in time.

The season of captured sharks has attracted special attention. Like a child, it gives light beyond simple presence. According to the principal investigator Dr. José Carlos Báezidentifying young people is important for understanding the status of the species in the area.
Dr. José Carlos Báez, the main researcher of the study, says: “It is very important to find out what kind of children the young people have. “The emergence of child models raises the question of whether there may be children in the area.”
The researchers added that this possibility challenges the idea that the region functions only as a transportation route. If reproductive activity is confirmed, even on a small scale, it will change the current understanding of how great white sharks use these waters.
Afraid of a Beast or a Precious Ocean Guardian?
Public perception of great white sharks is often based on fear, driven by rare but widely reported incidents. However the historical record analyzed in the study suggests that contact with Mediterranean Spanish waters is unique and not frequent.
The main idea that I want to tell the public is that these large marine animals have an important role in the marine environment. Baez “They act as natural scavengers – by eating dead flesh, they keep the environment clean.”
Listed as It is vulnerable to IUCN Red Listthis species is facing continued decline worldwide. Researchers explain that observing and following them for a long time is important to understand their behavior and protect them.
He said: “By shedding light on the biology and ecology of great white sharks, research can help replace baseless myths with reality.
