The sea contains some of the most beautiful life forms but also the most deadly ones.
Marine animals have an extensive arsenal of unique weapons to bite, bite, pierce, poison and chemically kill other life forms.
Some of these weapons have been clearly developed to help hunt and kill prey, such as jellyfish tentacles and octopus stings. Others have evolved for defense, such as spines of hedgehog or stonefish.
Scientists believe that the world’s seas hold some 1,200 different venomous fish species and estimate that they injure about 50,000 people per year.
