Description

The ID of this sponge was verified by looking at its spicules. It may be identifiable visually: this is the first large red/orange sponge with oscules on volcano-like mounds I have found in the area, and it turned out to be this species.

I have not seen Acarnus at other Goleta/Santa Barbara sites yet (Mohawk Reef, Elwood Reef, Arroyo Quemado, Arroyo Hondo, Isla Vista, Coal Oil Point, 1000 steps, Tajigus, etc.). Other UCSB divers have told me they only know of it at Naples, where this one was found. I saw several there.

This sponge was keyed out using its spicules. It was thinly encrusting on Phragmatopoma tubes (Note: this sponge can also be brown or purple.)

The yellowish sponge at the center of the photo keyed out to this species using The Sponges of California (based on microscopic spicules). The sponge to the right of it is something else.

I keyed out this hard, encrusting sponge using its spicules. A terrible photo, sadly, but you aren’t missing much. It was rather undistinguished in person.

Description

A very thinly encrusting sponge, light yellow color, with a network of surface tubes. The tubes are nearly transparent, and were not apparent on person, but can be discerned in the photos. This sponge was keyed out based on its spicules. I am not sure it it can be reliably distinguished from photos.

A very thinly encrusting yellow sponge. It is identifiable because of its distinctive spicules (shown in the later photos), but probably not identifiable in the field.

Description

Though I have not examined the spicules of this sponge, this species is likely. It was hard (but not as hard as Acarnus), and lacked the Acarnus “volcanos”. When collected, it slimed profusely, as this species does, but most other local orange species do not. It was also larger than the other orange Poecilosclerida I have found.

Description

I examined the spicules of this sponge, and they match this species qualitatively. This species was first sampled on the West Coast of Mexico in 1911. It was not found in California until 1986, when it was found at Catalina Island. The original description, of the Mexico sample, had somewhat larger spicules than this sponge and other California samples; there is some question as to whether this means that there is variation within a single species or more than one species in a complex. I suspect variation. (Spicules examined but not shown)

This sponge first sampled on the West Coast of Mexico in 1911. It was not found in California until 1986, when it was found at Catalina Island. The original description, of the Mexico sample, had slightly larger spicules than this sponge; it seems most likely that this is variation within the species, but it is possible that there is more than one species in a complex. The second photo shows the skeleton after proteinase K digestion and the third shows some example spicules.

I have examined the spicules of several sponges with this appearance from the Santa Barbara Channel. All had this prominent lacy membrane and often a “hispid” (hairy) look. All keyed out to this species, including this one.

Description

This sponge is unlikely to be identifiable in the field, as there are so many small orange Poecilosclerida found here. In the lab, however, this sponge keyed out easily. It was hard and incompressible, hispid, and lacked slime. The spicule content distinguished it from any other sponge known in California; a few spicules are shown in the last photo.

Description

I collected a sample of this thinly encrusting sponge and keyed it out using the Sponges of California. Its spicules include isochelae and toxa + tylotes, which mean it is either Antho karykina or A. lambei. The sizes of all the megascleres fit A. lambei and not A. karykina. One point gives me pause: the chelae look a little different than shown in the key. Third pic is of the megascleres.
