    Some first pictures of "Ramses". We're off out to collect some crabs from the rockpools.

    So we had our fun as ambush hunters and now Ramses has some crabs and blennies to hunt.

    Some more photos.

    Is the clam also a new addition?

    There is something about ceph eyes that make them particularly appealing. It may be that their iris (as least I believe that is the covering over the eye) appears very much like an eyelid and gives them a land animal appearance or at least sets them apart from fish. Perhaps it is that humans use eyes to signal emotion and animals that can't change their eye shape seem less friendly.

    No hunting seen yet, but the crabs seem wise to the danger and swim rapidly away. The fish are also looking slightly wary.

    The clam was not new D, but was right next to Ramses so I took its photo. This crinoid was new yesterday, something I had never seen alive before. It is spectacular when it walks on its cirri up onto a high rock and unfurls its arms.

    Can anyone confirm the ID of this cuttlefish? Now that I can study this one up close it will hopefully be possible to know. From the photos of the wild ones Thales thought Sepia pharaonis.

    I would think it was Sepia pharaonis also but I will have to do a little more research. It appears that there are 5 different clades (and maybe even species) of the group. Your cuttlefish would be part of the Persian Gulf/Arabian Sea clade.

    I love the crinoid too. I had two for several years but not this kind and both stayed hidden in the LR most of the time.

    Wow! Love the crinoid, I had never seen a live one either, and I just assumed they were all sessile, do you know what species yours is. Is it nocturnal?:cool:

    I feel very bad for one personality in the aquarium, "Brutus" the boxer shrimp who was lord of his world last week. He is now a nervous wreck hiding behind rocks and extremely jumpy if I so much as look at him. This morning before heading off for work I witnessed an explosive attack by Ramses and a very narrow escape for Brutus as he danced back down a narrow gap between rock and glass.

    I'm offering peeled shrimp to Ramses and he investigates, but doesn't take at the moment. He'd rather have the boxer shrimp. Crabs and blennies are all in hiding.

    Terri, the crinoid is certainly unfurled at night and spends some hours furled up during the day. I'm not sure what species it is. Here attached is a 10cm Cretaceous comatulid, Antedon, from Lebanon for comparison.

    LOL, I think you are looking for live specimens to match your collection. Interesting idea anyway :grin:.

    Harvey, our banded survived the addition of Winchester, our Trigger and continued to rule the tank. Unfortunately, after over a year, one arm disappeared. He grew it back with the next shed but then disappeared.

    Yes D, your right!:smile: The fact that Hajar has a fossil that so closely matches his furled, live crinoid is astounding (to me anyway). To see them side by side...great learning aid, although Hajar's fossil above is much, much younger than the crinoids I am finding.

    So, a moment ago I placed a crab next to Ramses and he turned slowly before explosively shooting out the feeding tentacles. There was a round of applause from the observers. Very impressive indeed!

    Brutus has twice lost his right cheliped in wrestling matches with the anemones, but has grown it back in between moults. I hadn't realized that they could do that.

    You are right, there are many good comparisons to make between the live animals and their ancient predecessors. Here are a few:
    - corals and turtles here
    - sea urchins here
    - cuttlefish here
    - shrimp here
    - fish here
