The giant volcano sponge (Anoxycalyx joubini) is a species of Antarctic sponge. [1] It is one of the largest sponges in the world which can grow up to a diameter of 1.5 metres (5 feet) and 1.95 metres (6.5 feet) in height. [2] The species may have an extremely long lifespan, with estimates of up to 15,000 years. [3]
However, due to changes in sea levels since the Last Glacial Maximum, its maximum age is thought to be no more than 15,000 years, [13] hence its listing of c. 15,000 years in the AnAge Database. [14] The shallow-water occurrence of hexactinellids is rare worldwide. In the Antarctic, two species occur as shallow as 33 meters under the ice.
Cinachyra antarctica is a species of antarctic sponge belonging to the family Tetillidae. [1] It was first described by H.J. Carter in 1872. [2] A 2002 study in Antarctica calculated that this sponge and another antarctic sponge, Anoxycalyx joubini, have amazingly long lifespans surpassing 1,550 years in C. antarctica and 15,000 years in A. joubini.

Eventually, the larvae attached to rocks and metamorphoses into sea sponge. In the adult stage, Euplectella are sessile and attached firmly to rocks through spicules. [21] It is unclear how long Euplectella generally live however other genus of glass sponge have been known to live up to 15,000 years in the wild. [22]

One study provides substantial evidence that an individual of this deep-sea sponge, that forms giant spicules up to 3 meters long, is about 11,000 years old. [ 3 ] Five other individuals collected from depths of 1,100 to 2,100 meters at three widely separated locations in the western Pacific Ocean were estimated to be 6,000 to 18,000 (±1,000 ...
