Ranging from 1860 to 2016, the data was utilised to develop spatial and temporal models on shark populations. Researchers collected 773 observations documenting the presence of white sharks. For the first time ever scientists have estimated the white shark’s presence in the Mediterranean over the last 160 years © Ingimage The drastic decline in recent years In response to this, the study seeks to collect a wide range of data to construct a bigger picture of the white shark’s habitat as well as its population density and fluctuations in numbers. It may therefore come as a surprise that the CNR’s research reveals that they’ve inhabited the Mediterranean Sea for centuries, a claim backed by recorded sightings dating back as far as Medieval times.ĭespite the species’ classification as “ critically endangered” by the International Union for Conservation of Nature (IUCN), an effective conservation programme can’t be undertaken in the absence of information regarding its status in this area. Great white sharks are renowned for their huge size, which may lead us to think that these creatures exist only the vast expanses of the ocean.

The research was supported by the Institute for Marine Biological and Biotechnological Resources (IRBIM) of the Italian National Research Council (CNR), the Anton Dohrn Zoological Station, a research institute in the Italian city of Naples, and the Italian National Institute For Environmental Protection and Research (ISPRA). The drop in the white shark population was revealed by Abundance and distribution of the white shark in the Mediterranean Sea, a study conducted by a group of researchers from La Sapienza University in Rome, Italy in cooperation with Stanford University and the University of Virginia, both in the US.
