Poison Jelly Sounds Fun, Oh Wait
Let’s just begin by saying that Box Jellyfish are the most toxic species of jellyfish in the world. What with their poison-lined tentacles we can’t be surprised at that fact. Their tentacles inject a potent mixture of toxins which then attack the skin, heart, and nervous system. Now an antivenom exists but most victims fall into shock and die before ever receiving treatment. Beware greatly if you’re in the tropical Indo-Pacific region or tropical and subtropical oceans.
SSSSSSSSidewinder
Usually found in desert areas in southwestern United States and northwestern Mexico, the Sidewinder is no joke. While one bite isn’t fatal, the symptoms of a bite are incredibly damaging.
