“…The Amazon estuary has at least four mullet species (Menezes, Nirchio, Siccharamirez, & Oliveira, ), and it is highly possible that one or more of these taxa undertake short‐distance anadromous migrations, but little is known about their life histories (Barthem, ). The bull shark ( Carcharhinus leucas , Carcharhinidae) and the large‐tooth sawfish ( Pristis pristis , Pristidae) have been captured at least 3,000 km upstream in the Amazon, although they are considered to be opportunistic and not obligatorily migratory (Garrick, ; Thorson, ; Werder & Alhanati, ). The presence of newly born individuals (0.6–0.8 m length) of both species in the brackish and freshwater of the Amazon coast indicates they can use the Amazon estuary as a nursery area.…”

“…Thorson (1972) provides 20 records for the species in the Amazon River and its tributaries comprising juveniles and adults from both sexes. Werder & Alhanati (1981) provide three more records of sharks captured well within the river. Further records come from Soto & Nisa-Castro-Neto (1998), Karl et al (2011), Gausmann (2018, and a record of a specimen captured in Santarém, Pará state in 2018 (https://glo.bo/31HBxnK).…”

“…Ainda não são conhecidas as taxas de mortalidade natural para esta espécie (FLORES, 2002). Em água doce, o único predador possível do tucuxi é o tubarão-cabeça-chata (Carcharinus leucas), que ocorre comumente no alto e médio Amazonas (WENDER;ALHANTI, 1981). O tucuxi é um golfinho social, geralmente encontrado em grupos de 2 a 6 indivíduos, sendo que as maiores agregações são vistas durante a alimentação.…”
