The yellow tube sponge stands vertically in groups of several tubes joined together at their base, much like the pipes of an organ, but less organized. The various members of these small colonies of yellow tube sponges display varying sizes depending on their age. The maximum height for the largest specimens is around 3 feet, with a diameter of about 8 inches.

Reproduction
The yellow tube sponge exhibits both asexual and sexual reproduction !
The yellow tube sponge reproduces:
by budding, where a small growth forms, detaches and once settled on the ground, gives rise to a new sponge
or by division - following an external incident, a piece of the sponge that is severed regenerates into a new sponge
and finally by the emission of sexual gametes into the water. Indeed, the yellow tube sponge is hermaphroditic, meaning it simultaneously releases male and female gametes, which is manifested by the strange impression of smoke escaping from the sponge.
