From ESW's "Mad Scientifical Chemistry" Collection is this Special Science Beaker that contains the ONE of the DEADLIEST CREATURES IN the world… A baby MAN O' WAR JELLYFISH!

The Man O' War JellyFish (also known as Physalia) is part of a complex hydrozoan colony and features a hat-like float and tentacle. Its venomous tentacles can deliver a powerful sting. The name "Man O' War" is taken from the man-of-war, a 16th century English armed sailing ship that was based on an earlier Portuguese vessel. Despite its outward appearance, the man o' war is not a true jellyfish… its actually a siphonophore, which differs from jellyfish in that it is not actually a single creature, but a colonial organism!

The round bottom "boiling flask" beaker is filled with a safer, less toxic form of Formaldehyde, which keeps this lil killer well preserved inside. The beaker has been sealed with a glued cork for extra protection ,)

When displayed in bright light, this beautiful specimen bottle reflects deadly magic around the room!

Great addition to those extra special curious collectors. Would also make a great teaching specimen for kids, HOWEVER, we do not recommend this for young children.

*Please Note: Toxic venom has been removed from persevered specimen so it cannot actually sting or kill anyone.

Beaker measures approx: 4.5"H
