The 21 pages that link to Sponge, each with the reason it gives.

• Filter feedingBroader topic: Specialized cells capture food particles from water flowing through the sponge.

• CnidariaCompared with: Sponges provide a comparison with cnidarians' organized tissues and nerve cells.

• AnimalBroader topic: Sponges show that animals need not have nerves, muscles, or conventional organs.

• Suspension feedingBroader topic: Specialized cells capture suspended food as water passes through their bodies.

• Bilateral symmetryCompared with: Many sponges have irregular forms rather than a bilaterally organized body plan.

• BuddingRelated: Some sponges reproduce asexually by forming buds that detach or remain attached.

• Animal phylogenyBroader topic: Whether sponges or comb jellies branch first remains a major phylogenetic dispute.

• Gastrovascular cavityCompared with: Sponges lack a gastrovascular cavity and distribute digested nutrients among cells by other means.

• InvertebrateBroader topic: Sponges show how far animal organization can differ from vertebrate anatomy.

• Germ layerCompared with: Sponges show that early animal development does not always produce true germ layers.

• ChoanocyteNarrower topic: Choanocytes are a defining cell type across this animal phylum.

• SpiculeNarrower topic: Spicules are structural elements found across many sponge groups.

• Hawksbill sea turtleRelated: Many hawksbill populations eat sponges, including species defended by toxins or spicules.

• Calcareous spongeNarrower topic: Calcarea is one lineage within the broader sponge phylum.

• Ingestion (biology)Broader topic: Its cells ingest captured particles from water moving through the body.

• DemospongeNarrower topic: Demosponges are members of this phylum, alongside glass sponges and calcareous sponges.

• DromiidaeRelated: Sponges are frequent coverings carried by dromiid crabs.

• ElacatinusRelated: Some Elacatinus species live among sponges rather than acting as cleaners.

• HexactinellidNarrower topic: Hexactinellids are sponges with a distinctive silica-based skeleton.

• HomosclerophoridaNarrower topic: Homosclerophorida belongs to this phylum of structurally simple animals.

• Spongia officinalisNarrower topic: The species belongs to this phylum, whose water-filtering body plan defines sponge biology.
