Held on Sat 21.1.18. Brilliant. Rod Morris lead this excellent course. Have a look at the recent (2017) Collins Field Guide to the New Zealand Seashore written by Sally Carson and Rod and you will see the quality of the photographs. And thanks to the Marine Studies Centre for running this course. The beach was the subject of much rock turning as we found animals to photograph. A lot of treasures turned up aswell. I am just exploring how to upload my images. I have resized quite damatically to get them to upload. I am not sure how to label those I know.
Great photos Jennifer - great to hear that you enjoyed the course. I have commented on your photos in order below:
1. Great tip from Rod - use a photo to cut out reflection or shadows on the seashore
2. Aeolid nudibranch, Aeolidiella drusilla, looks like you may have a photo of two mating.
3. Egg case of Aeolidiella drusilla, or at least that is my best guess as the adults were quite close.
4. Eggs of the bobtail squid, Sepioloidea pacifica. Once they hatch the juveniles move into deeper water.
5. Encrusting sponge comes in many colours and forms - not always easy to identify from a photo. Maybe the breadcrumb sponge, Halichondria panicea.
6. Dorid nudibranch, Alloiodoris lanuginata, laying its egg mass.
7. Close up of the egg mass - can you see the developing embryos?
8. Nudibranch egg masses are usually laid in a coil and attached to the rock.
9. Neptunes necklace, Hormosira banksii, is a brown seaweed. Little horn snails, Zeacumantus subcarinatus, are crawing over the surface probably feeding on the microalgae on the surface of the plant.
10. Snakeskin chiton, Sypharochiton pelliserpentis, hiding in an oyster shell.
11. Snakeskin chiton gets it name from the scales and colouration of the mantle, the tissue around the edge of the shells.
12. Colonial seasquirts look quite different when you zoom in. You can clearly see the individuals zooids living together in a jelly tunic in this picture.
Your photos show the vast variety of live on the shore. The Collins Guide to the NZ Seashore has more info about each species.
