Common Name: Paired-bell Siphonophore
Description: Under a small float of gas are a series of pairs of swimming bells. Under these bells is a rigid structure (siphosoma) that appears to be built by angle brackets after which may extend numerous tentacles (usually in a spiral pattern) to feed (rotation of water through the relaxation of the tentacles in the form of a large rotating spiral). The identification is made by observation of the annexes in the form of point (tentilla) found in the tentacles. Toxic in contact with the tentacles causes a short, but intense sting.
Habitat: Floats in the open sea at depths up to 40m.
Color: Transparent to translucent color.
Dimensions: The tentacles can be up to 30 inches in length.
Geographical Distribution: Caribbean Sea Western Central Atlantic
