Aquatic Hawaiian Wildlife

[Cepheris]

Was visiting family in Hawaii recently and found some little friends on a trip to the beach.  Was wondering if anyone here could ID them

Welcome to the community @Cepheris!

 

Those are some beautiful Hawaiian tide pool finds. Which island were you on?

 

@yoshii might be able to ID some of these.

We found them at the Kaʻena Point albatross sanctuary tidepools on O'ahu.  The first critter was found in a freshwater puddle from the recent rain on the hike up, the next three were in the tide pools, and the little yellow crab was found on a beach on the hike back

The second pic is most likely some form of Rock Crab, though that doesn't narrow it down much cause there's a ton of different varieties of those in HI.

My guess was horse shoe crab, but after doing a quick google search, I think you're right.

I remember when I was a rugrat I had a kit where you can have them as “pets”. But the one in the picture looks huge compared to the ones I remember having.
