These lethal fish are members of the taxonomic suborder known as Myliobatidae. Stingrays can grow up to around 35 centimeters in length, and their ability to sting with venom makes them extremely dangerous for other animals, as well as humans. Apart from death, their sting can cause muscle cramps, trauma, and painful swellings.
Stingrays are carnivores and have a keen sense of smell. They do not use their dorsal eyes to locate their prey; instead, they have electroreceptors, which they use to great effect in order to spot other animals. Even though this species is present all over the world, many are registered as endangered or vulnerable, meaning that these fish should not be hunted and need to be preserved.

Manta alfredi and Manta birostris are the only two manta ray species present in the world. Their body sizes are enormous and they can grow up to more than seven metres in width. In addition, an adult manta ray can weigh up to a staggering 1350 kilograms. These fish have a triangular body, with paddle-like lobes right in front of the mouth. The mouth is considerably large, and has eighteen rows of teeth just on the lower jaw. These big fish are found in tropical and sometimes subtropical marines. Another unique characteristic of this species is that they let smaller fish, such as wrasse, remora and angelfish, clean their gills by feeding on any particles; in this way, they also stay free of parasites. This species is characterised by dark colours on the dorsal side and lighter colours on the ventral region.
