Rays are poisonous, but not all rays are poisonous. There are many species of rays. Most rays are non-toxic, and only a few are poisonous. Black and white rays, for example, are poisonous species. They have a triangular stinger at the tail, which is not obvious, but can be seen if you look closely.
When humans are stabbed by stingray stings, redness and fever may occur. If it is serious, it may endanger life. After being stabbed by the stinger of rays, the wound pain will first appear, which will turn into intermittent pain for about one hour. And the injured part began to appear red and swollen, accompanied by nausea, dizziness, vomiting, spasm and other symptoms. If it is not handled in time, it is easy to die after secondary infection.
2. Can rays be raisedRays can be raised because they have low requirements for the environment and strong adaptability. As long as they can ensure that their living environment is comfortable and stable, they can grow well. However, rays have stingers on their tails, so it is best to cut off their tails when raising them to avoid their stingers hurting humans. In addition, the skin of rays is sensitive, so salt should not be used when breeding them, otherwise it will cause damage to their skin.
