Скачать или смотреть Fingered goblet sponges support bustling communities of life in the deep sea

The fingered goblet sponge (Heterochone calyx) is one of the largest sponges on the Pacific coast. Their funnel-shaped bodies can grow up to two meters (nearly seven feet) tall and fan out two meters (nearly seven feet) across. Remarkably, the skeleton of this massive animal is made of microscopic slivers of silica glass called spicules. As the sponge grows, the glass spicules fuse together, creating rigid joints in between. This intricate three-dimensional structure remains intact long after the tissues die.

Fingered goblet sponges support bustling communities of life. Much like coral reefs in tropical waters or the old-growth forests on land, countless critters make their home in sponge gardens.

Decisions we make in our everyday lives can affect all animals, even in out-of-sight places like the deep sea. Increased demand for metallic minerals could lead to mining in pristine areas of the deep sea, harming animals like Heterochone. Share what you have learned about Heterochone and sponge gardens to help protect these unique habitats. Help us spread the word about safeguarding the ocean’s pristine wilderness. The future of our big blue backyard depends on us.
