Many of the cloud sponges in fjords have irregular shapes dominated by broad mittens or “elephant ears”  Note that the broad surface of the mittens tends to be oriented vertically. (Discussed further under Keeping Clean)

Cloud Sponges on Hecate Strait Sponge Reef

Sometimes the cloud sponges have a simpler vase shape but again with  vertically oriented  mittens.

They can also be tubular with smaller mittens.

Tubular Cloud Sponge from Jervis Inlet

Some tubes lack mittens and can be confused with another species of glass sponge.

Some of these are likely Cloud Sponges based on retrieval of samples.

One specimen in a crevice in an area of strong tidal currents has a convoluted but very compact form
