Portuguese man o' war
The Atlantic Portuguese man o' war lives at the surface of the ocean. The gas-filled bladder, or pneumatophore, remains at the surface, while the remainder is submerged. As the Portuguese man o' war has no means of propulsion, they move according to the winds, currents, and tides. Although they are most commonly found in the open ocean in tropical and subtropical regions, they have been found as far north as the Bay of Fundy, Cape Breton and the Hebrides.
Spot (comics)
His preferred method of attack is to surround his opponent with numerous spots, allowing him to punch or kick them from unexpected angles across great distances. This proved very effective against Spider-Man as his spider-sense was unable to detect incoming attacks from another dimension, effectively negating this ability (and although the Spot's lack of super-strength meant that his punches did not actually do much damage even when they did connect, the cumulative effect could prove dangerous in an extended fight). The same phenomenon was true when Spot flung Spider-Man through a warp and he reappeared in this dimension too close to a wall to dodge. However, on Daredevil, who also has superhuman senses, this trick does not work, as his Radar Sense could easily detect the teleportation energy in the Spot's body, making it simple for him to tell where the Spot was going to attack from. The Spot can also move the spots on his body to protect himself from physical attack by positioning one in the path of a punch or kick, causing the attack to pass harmlessly through a warp.
