Rays are widely distributed animals and when trampled on, they cause serious accidents. These animals have important representatives such as the Dasyatidae family and the Potamotrygonidae, the latter belonging to the freshwater environment. In the municipality of Soure on the island of Marajó, there are records of accidents involving these animals every year, so it is necessary to analyze the morphology of the ray stingers and compare between the species captured in the municipality.
For this purpose, the needles were removed from the species during artisanal fishing in the municipality and fixed in 10% formalin. Subsequently decalcified in a solution containing 5% EDTA to carry out histological procedures, which involve inclusion in histological paraffin, cutting of europe mobile number list Rays are widely distributed animals and when trampled on, they cause serious accidents.

Therefore, studies on the characterization of stingers are important, as they help to understand the defense mechanisms of these animals. Keywords: Freshwater, marine, ichthysm, venom, morphology. 1. INTRODUCTION Rays are poisonous animals that are related to many accidents with humans (GARRONE NETO and HADDAD, 2010; SAMPAIO, 2014). These animals have a wide distribution, in the marine ones, for example, from the Dasyatidae family, they can occur throughout the Brazilian coast, while the Potamotrygonidae family belongs exclusively to the freshwater environment and can be found in most of the river systems of tropical South America (ROSA, 1985).
