Mermaid's glove

The mermaid's glove has decorative branches which often fuse together, resembling antlers. In Dutch, it is called 'antler sponge'. If the waters are calm where it grows, the branches are thin, resembling fine fingers. Probably the reason it's called mermaid's glove in English. In wilder waters, the branches are wider and flatter. This sponge gets its food by sucking up water through tiny pores. Other pores visible on the branches are used for expelling the filtered seawater.

  • Distribution and habitat

    You find mermaid's glove in the delta region. It grows on hard substrate below the low-tide mark down to 100 meters deep. As a species, it lives in the northern Atlantic Ocean and bordering seas.
