Needlefish
These fish can grow up to 1.4 meters long, they are not vicious and are not responsible for many deaths. However, they may not contain a venom, poison nor are they aggressive but they have needle-like teeth that pack a very strong bite. More than this they can become airborne, f;lying through the air and piercing anything in their way. They are found in tropical waters relatively close to shores.

Yellow Sea Anemone
Most sea anemones are harmless to humans but this one is certainly not. The effects on humans are not as bad as what they do to prey- their venom contains neurotoxins that paralyze prey which allows them to use their tentacles and move the prey towards their mouth. The only fish unharmed by this is, yes, Nemo. Clownfish use anemones to protect themselves from prey.
