Jellyfishes [noun]

These jellyfishes are common on the Florida coast, huddled together on the sands of the coral reefs.

But the diminutive cousin in the grotto with the jellyfishes is a bird of quite another feather.

Some jellyfishes are so poisonous that they are most dangerous even to man.

The Rhizostom, or root-mouth jellyfishes, are very remarkable.

These are the bodies or parts of bodies of jellyfishes which have been cast up by the waves.

Jellyfishes vary in size from that of a pinhead to six or seven feet in diameter.

This is true of the jellyfishes which float or swim about on or near the surface of the ocean.

Not all medus or jellyfish are produced by polyp individuals, nor do jellyfish always produce polyps and not jellyfishes.

The most interesting members of the class are the "colonial jellyfishes," constituting the order Siphonophora.

The beautiful "Portuguese man-of-war" (fig. 13) is one of these colonial jellyfishes.
