taxonomic rank: species
Basionym: Collozoum serpentinum Haeckel 1887

Catalog entries: Collozoum serpentinum

Original description: Central capsules cylindrical, filiform, much elongated, ten to one hundred times, sometimes two hundred to four hundred times as long as broad, snake-shaped or worm-shaped, curved and contorted in the most irregular manner, often spiral or twisted into a large nodule. Numerous oil-vesicles constantly present, forming one series of globules in the axis of every capsule; distance of the globules, one from another, and also from the capsule-membrane, about equal to their diameter. (This interesting and very curious form was very frequently observed living by me in the Canary Islands, in January 1867; the jelly-colonies were commonly spherical, and contained fifty to two hundred or more capsules of very different size and form.).

Length of the central capsules 1 to 10, sometimes 20 to 40 mm.; average breadth 0.1 mm. [dimensions in mm]
Remarks on original description: Haeckel listed Collozoum serpentinium under the subgeneric name Collophidium and uses the other name Collophidium serpentinum in the figure description.
