Question by Diane May:I dived Partridge on Saturday 4th September, and saw this strange looking object. I was curious to know what it is. I cannot find it in any of my identification books. It was quite large, around a 10cm white dome with black spots. It appears to have a breathing hole on the top (?). Is it perhaps a mollusk with a very large mantle? Please could you help me identify it.
It is the mantled keyhole limpet, a moderately uncommon sighting. For more details click here.

Question by Johan Swanepoel: Am I on the correct path to say that the hairy cover over the snails (the whelk Nucella speciosa?) is family of the High-spine commensal hydroid (Hydractinia altispina) My problem though is that in the Two Oceans this hydroid is not supose to be in our area (Port Elizabeth).
No, this is not correct - it is instead the papery burnupena shell, covered with the bryozoan Alcyonidium nodosum - which may imply there is a range extension, as neither are know to occur in Port Elizabeth. For more details click here.

Question by Paul Papenfus: Can you help me with identification of some nudibranchs from Aliwal Shoal. The first image is what I understand to be the "real" C. Africana and the next one is what I'll call the liquorice variant until I get a better name.
Neither of the two images submitted actually show Chromodoris africana - they are actually C. hamiltoni! For more details click here.

Question by Geo Cloete: The firefish in the photo, is that the Devil firefish? I always thought this species was called lionfish, but now see in the Two Oceans they name it firefish. Can both names be used or are there a difference between fire and lionfish?
Well, it seems like this is indeed the devil firefish, or rather, the accepted common name for it, but common names are, in essence, a nuisance... For more details click here.

Question by Johan Swanepoel: I thought at first that these were gasflame nudibranchs (Bonisa nakaza) but only a light blue version, but then I saw a photo of the juvenile silvertip nudi (Janolus capensis). Now these photos look to me more like the silvertip???
While indeed confusing, this to me is most likely to be a gasflame after all.

Question by Johan Swanepoel:My friend Glen Jacoby and I were diving in Algoa Bay, where he took these images. Once again I cannot id this nudibranc. I first thought that this is a  a juvenile orange-clubbed nudibranch (Limacia clavigera) because of the red spots on the body and orange cerata with red tips but the two long cerata threw me off track again. May this be a juvenile Okenia amoenula?
Yes, this is indeed the fiery nudibranch, Okenia amoenula

Question by Johan Swanepoel: Can you help me Id this nudibranch?
I took this photo at a depth of about 10 m at out reef the Bellboy in Algoa Bay.
At first I though this may be the Elegant Nudibranch (Cratena sp.1) (Nudibranchs of the Cape Peninsula and False Bay page 97) or the Orange Eyed nudibranch (Cratena capensis) (Page 96) but the cerata seem too dense on the photos. Can this perhaps be the Indian Nudibranch (Aeolidiella indica) (page 99)? If you look on the one photo you will see the orange spots on the head.
This is Cratena sp.4, a barely known species found in your area.
