Der Große Vasenschwamm (Xestospongia testudinaria) ist eine Art der Schwämme und gehört zur Klasse der Hornkieselschwämme.
Die Gestalt dieses Schwammes ist meist tonnenförmig und erreicht im Gezeitenbereich eine Höhe von etwa 20 cm, in tiefen Gewässern kann sie Größen von mehr als 2 Metern erreichen.[1][2] Der Durchmesser liegt im Bereich zwischen 10 und 20 cm. Das Farbspektrum vom Großen Vasenschwamm reicht von Brauntönen bis Rosafarben, wobei die Öffnung in der Regel weiß ist.[3] Sie besitzt eine tief gefurchte und harte Oberfläche. Innerhalb des Schwamms kann sich eine große Vielfalt an Lebewesen, beispielsweise Hummer, Garnelen oder Seegurken, ansiedeln.[2]
Man findet den Großen Vasenschwamm im Indopazifik, in der Gegend von Indonesien, den Philippinen, Australien und Papua-Neuguinea. Sie kommen sowohl alleine als auch in kleinen Gruppen in einer Tiefe von 2–55 Metern vor.[2]
Die Vasenschwämme sind zweigeschlechtlich, also Lebewesen mit männlicher und weiblicher Geschlechtsausprägung und gehören somit zum Hermaphroditismus. Die Zygote entwickelt sich zu einer schwimmenden Larve, die sich im Wasser frei bewegt und sich schließlich am Boden absetzt, um sich zu einem neuen Schwamm zu entwickeln.[2]

Xestospongia testudinaria is a species of barrel sponge in the family Petrosiidae. More commonly known as Giant Barrel Sponges, they have the basic structure of a typical sponge. Their body is made of a reticulation of cells aggregate on a siliceous scaffold composed of small spikes called spicules. Water is taken into the inner chamber of the sponge (known as the spongocoel) through ostia (small pores created by porocytes). Flagellated choanocytes line the inner chamber and help generate water currents through the sponge.
Due to the amount of water that Great Barrel Sponges filter throughout their lifespan, they perform an important ecological role.
This species is found in the Philippines,[2] Australia,[1] western and central Indian Ocean, Indonesia, Malaya and New Caledonia. These sponges are sessile filter feeders, with a very important role in the ecosystem. Giant Barrel Sponges filter a tremendous amount of water throughout their lifespan (some living up to 2000 years) which increases water clarity, controls algae, and affects coral populations. These sponges also serve as a habitat for many other species such as other invertebrates, benthic fish, bacteria, and cyanobacteria.
This species is maroon to pink, with the opening of the barrel pale white.
Specimens are often found emerging from an apparent common base. In the intertidal zones, this species ranges from 10 to 20 cm in diameter, and are about 10 to 20 cm tall.[3]
A bioactive peptide consisting of 13 amino acids, KENPVLSLVNGMF, has been identified from this species. The peptide was selectively toxic to human cervical cancer cells (HeLa), but non-toxic to non-cancerous, human embryonic kidney cell line (HEK 293 cells).[4]
Currently this species is not considered endangered or threatened by any agencies, however there are a list of potential threats that may effect their survival. Among these threats include fatal diseases such as Sponge Orange Band (SOB), environmental changes, and cyclical bleaching. Researchers are unsure what the cause of SOB is, but evidence supports the hypothesis that environmental changes, rising water temperature in particular, is responsible for the disease.

La esponja barril (Xestospongia testudinaria) es una especie de demosponja de la familia Petrosiidae con forma de barril.
Esta especie se encuentra en Filipinas, Australia,[2] el oeste y centro del océano Índico, Indonesia, Malasia y Nueva Caledonia.
Esta especie tiene diferentes colores que van desde marrón a rosa, con la apertura pálida. En las zonas intermareales, esta especie varía entre 10 y 20 cm de diámetro, y mide alrededor de 10 a 20 cm de altura.[3]

Éponge baril
Xestospongia testudinaria, appelée communément éponge baril ou éponge en tonneau[1], est une espèce d'éponges de la classe des démosponges, de l'ordre des Haplosclerida et de la famille des Petrosiidae.
C'est une grande éponge pouvant atteindre plus de 2 mètres de haut, dont la forme évoque un baril. Elle vit dans les eaux chaudes du Pacifique-Est, sur les récifs coralliens, de 2 à 50 mètres de profondeur.
Il existe un autre type de démosponge du même genre appelé Xestospongia muta, assez similaire à Xestospongia testudinaria mais vivant dans la mer des Antilles.

Xestospongia testudinaria adalah spesies spons yang tergolong dalam kelas Demospongiae. Spesies ini juga merupakan bagian dari kelas Demospongiae, filum Porifera, subregnum Parazoa, dan kingdom Animalia.
Seperti spons pada umumnya, spesies ini memiliki tubuh yang berpori dan permukaan yang keras seperti batu. Selain itu, Xestospongia testudinaria juga dapat menyerap oksigen dari air melalui proses difusi.

Xestospongia testudinaria (reuzenvaasspons, grote kelkspons of tonspons) is een sponsdiersoort die behoort tot de klasse van de Demospongiae of hoornsponzen. Er worden twee ondersoorten onderscheiden: de nominaatvorm Xestospongia testudinaria testudinaria, en Xestospongia testudinaria fistulophora.
De soort komt voor op grotere dieptes langs rifwanden van de Stille en Indische Oceaan. Het tonvormige lichaam is opgebouwd uit een skelet van naalden en hoornvezels of alleen van hoornvezels. Deze sponzen kunnen zeer grote afmetingen van wel 1-2 meter bereiken, en vormen een onderkomen voor allerlei kleine ongewervelde dieren.
