    Presence and abundance of the neotropical otter (Lontra longicaudis annectens) were聽established in the locality of Tlacotalpan, Veracruz, during north and hurricane seasons in 2007 and dry聽season in 2008, where it was carried out a monitoring process in two zones (i) the Papaloapan River聽margins, and (ii) streams and lagoons near to the locality. Furtheremore, interviews to local inhabitants聽were carried out in order to obtain information about biological aspects of the species based on the local聽knowledge shown by the inhabitants. On the other hand, 61 feces, 13 latrines, and two borrows were聽located. Moreover, two individuals were observed and recorded. During November 2007 the abundance聽recorded in two zones within the study area was 1.22 and 0.61 otters/km. In April 2008 the same two zones showed 0.43 and 0.21 otters/km. Finally, 100% of the interviewees know the river otter, and 99% of them consider that the species is relevant to the aquatic ecosystems and it must be protected.Durante la temporada de nortes y huracanes en el a帽o 2007, y la de secas en 2008, se document贸聽la presencia y abundancia de la nutria neotropical (Lontra longicaudis annectens) en Tlacotalpan,聽Veracruz, por medio de monitoreos en dos zonas (i) las orillas del R铆o Papaloapan, y (ii) en los m谩rgenes聽de arroyos y lagunas cercanas a la localidad.
