Mycale grandis is 'n sponsspesie in die taksonomiese indeling van die Demospongiae (gewone sponse). Die liggaam van die spons bestaan uit kieselnaalde en sponginevesels en is in staat om baie water op te neem.
Die spons behoort tot die genus Mycale en tot die familie Mycalidae. Die wetenskaplike naam van die spesie is die eerste keer geldig gepubliseer in 1867 deur Gray.

Mycale grandis, the orange keyhole sponge, is a species of marine demosponge in the family Mycalidae. Mycale is a large genus and this species is placed in the subgenus Mycale making its full name, Mycale (Mycale) grandis.[1]
Mycale grandis is a bright orange colour both outside and inside. It forms encrusting masses which can reach 1 metre (3 ft 3 in) across and 0.5 metres (1 ft 8 in) thick. The consistency is compressible but firm and fibrous and the sponge can be torn. The surface is smooth and undulating. There are a few large openings called oscula and a greater number of smaller openings called ostia. Water is drawn in through the oscula and expelled through the ostia after having had minute food particles removed by specialised cells. The inside of the sponge is hollow and often contains small brittle stars.[2][3]
The native range of Mycale grandis is Australia, Indonesia, Malaysia and India. It has spread to Mexico and to Hawaii where it is considered an invasive species. It is part of the fouling community and is found on man made structures such as harbour walls, wharves and pilings and in disturbed habitats such as freshly dredged channels and lagoons.
In Hawaii, Mycale grandis was first reported from Pearl Harbor in 1996. Since then it has moved out of its normal habitats and is also found on reef slopes in Kāne'ohe Bay where it is overgrowing and suppressing native coral species such as Montipora capitata and Porites compressa. A study that took place from 2004 onwards found that it was spreading to further sites. Attempts were made to remove the sponges mechanically but the results were equivocal; regrowth of the sponges occurred and the corals were damaged inadvertently. Further trials included the injection of compressed air into the sponges. This proved more successful.[4]

Mycale (Mycale) grandis adalah spesies spons yang tergolong dalam kelas Demospongiae. Spesies ini juga merupakan bagian dari genus Mycale dan famili Mycalidae. Nama ilmiah spesies ini pertama kali diterbitkan pada tahun 1867 oleh Gray.
Seperti spons pada umumnya, spesies ini memiliki tubuh yang berpori dan permukaan yang keras seperti batu. Selain itu, Mycale (Mycale) grandis juga dapat menyerap oksigen dari air melalui proses difusi.
