Need help with some IDs from Philippines - Invertebrates

[vondo]

I've got two posts. This one some invertebrates, the other with fish, that I have not been able to identify from a trip mostly to Anilao but also to Puerta Gallera. I'd appreciate any help anyone can give me. Thanks in advance.

#1 - Tiny crab

#2: Another tiny crab

#3: Hermit crab that I could not match legs and eye-stalks against a book

#4 These tiny crabs were running between the base of a pair of crinoids

#5: This tiny crab is at most 5mm across

#6: Sea cucumber that I did not find

#7: The next two are of the same cuttlefish. He's maybe 2"/5cm long.

#8: Lastly a shrimp I could not ID

To help with your crab search it helps to know what they were on. A search term to get you started is "acro crab". There's lots of specialized crabs that have a symbiotic relationship with certain corals and anemones.
