Because they are at the mercy of prevailing wind, they much end up mass-stranding on beaches during the spring and summertime month.

The Canvas: A clay, translucent ridge that catches wind for travel.
The Tentacles: Small, downward-hanging fibril that seizure plankton.
The Color: A distinct co blue that aid camouflage them against the surface h2o.

Analyzing Stinging Potential

While they do possess nematocysts - the microscopic stinging cell mutual to all cnidarians - these cell are broadly too weak to penetrate human hide. The primary determination of these cell is to paralyse petite planktonic organisms, such as fish egg or copepod, rather than to defend against larger predators like humans.
