According to IUCN the percentage of sharks of the Northeast Atlantic and of the Mediterranean included in the red list of endangered species is the highest in the world. Of all the species examined, about one third are threatened with extinction due to:
- their slow increase in numbers,
- the reduced number of offspring, born after a long gestation or incubation period,
- the habit of many species to aggregate in large groups in the reproductive period (which makes them more vulnerable to fishing),
- the presence of nursery areas, where sharks go to give birth to their young, which are subject to environmental degradation and pollution.
These characteristics of their biology and behaviour contribute to making this group of fish, which has existed for millions of years, a threatened species. tened species.
