About Unprovoked Shark Attacks at Pernambuco’s Inshore Waters

Abstract

Unprovoked shark attacks have suddenly started at Pernambuco’s inshore waters from 1990s onwards. Some studies have pointed out different hypotheses to explain the reasons for this anomaly in the coast of Pernambuco. However, inconsistencies concerning some of these hypotheses indicate the need of further investigations to clarify which environmental and anthropic factors are driving such abnormal incidents with sharks in the south coast of Pernambuco.
