At the top was a hole, which may be an osculum, if they were indeed true sponges.

The size of the osculum is regulated by the myocyte.

There is an osculum at the apex of the sponge.

Other individuals have a number of vertical tubes, each with a large opening called an osculum at the end.

Some species can contract the osculum independently of the rest of the body.

The name is a reference to the osculum infame.

The osculum at the tip is fringed with fine spicules.

All the water is expelled through a single osculum at about 8.5 cm per second, fast enough to carry waste products some distance away.

Osculum infame is the name of a witch's supposed ritual greeting upon meeting with the Devil.

This species occurs as flat white or yellow encrustations up to 3 cm in diameter with a central osculum.

Osculum Obscenum is Hypocrisy's second album, released in 1993.

Each one narrows at the apex into a large osculum and this may be surrounded by small, finger-like projections.

Myocytes are thought to be responsible for closing the osculum and for transmitting signals between different parts of the body.

Species of this genus usually appear as groups of curved vases, up to 2 cm long, each ending in an osculum.

He introduced in his church the primitive custom of the osculum pacis and the agape celebrated as a common meal with broth.

Most sponges work rather like chimneys: they take in water at the bottom and eject it from the osculum ("little mouth") at the top.

Hypocrisy did a cover of the song "Black Metal" on the album Osculum Obscenum.

In mathematics, osculate, meaning to touch (from the Latin osculum meaning kiss), may refer to:

Water enters the spongocoel through hundreds of tiny pores (Ostia) and exits through the larger opening (osculum).

(Mr. Ahmadinejad's was a classic osculum.

Wastes diffuse into the water and the water exits through the osculum at a velocity of nearly 8.4 cm/second, carrying away with it the sponge's wastes.

By cooperatively moving their flagella, choanocytes generate a flow of water through the sponges pores, into the spongocoel, and out through the osculum.

The osculum infame is mentioned in nearly every single recorded account of a witches' sabbat and in confessions - most of which were extracted under torture.

The osculum is an excretory structure in the living sponge, a large opening to the outside through which the current of water exits after passing through the spongocoel.
