A young great white shark was captured off the coast of spain, leading to further research that confirms its presence in the Spanish mediterranean. This rare encounter prompted scientists to delve into past records dating back to 1862, resulting in a comprehensive review published in the open-access journal Acta Ichthyologica et Piscatoria.
On April 20, 2023, local fishermen caught a juvenile great white shark (Carcharodon carcharias) measuring approximately 210 cm and weighing between 80-90 kg off the eastern peninsula. The accidental capture provided valuable insight into the elusive “ghost” population of great white sharks that inhabit these waters. Currently listed as Vulnerable on the IUCN Red List, this species is facing a declining population trend.

The review of records spanning over a century revealed that while the Mediterranean great white shark remains elusive, it continues to inhabit these waters sporadically. The sightings of this species are still considered rare events.
dr.José Carlos Báez, the lead researcher of the study, states that “determining the presence of juvenile individuals is crucial.” He further hypothesizes that these sightings may indicate active reproduction in the region.
The Perception of Great White Sharks
This study confirms the continued presence of great white sharks in Spanish Mediterranean waters, albeit infrequently. The research highlights the importance of long-term observation programs to understand the biology and behavior of this iconic apex predator. By combining direct sightings with advanced tracking methods,evidence-based strategies can be developed for their conservation.
“the oldest and strongest emotion of mankind is fear, and the oldest and strongest kind of fear is fear of the unknown.” This famous quote by H.P. Lovecraft emphasizes that scientific knowledge can dispel unfounded myths about great white sharks.
concludes Báez.
Dismantling Misconceptions, One myth at a Time
The decline in great white shark populations highlights the need for long-term monitoring programs to protect these vital marine animals. As highly migratory pelagic species, they play a crucial role in redistributing energy and nutrients across vast distances. They also serve as nature’s scavengers by consuming carrion, keeping ecosystems clean even after death as their descent to the seafloor provides nourishment for deep-sea communities.
