They either make fake starfish for decorations or just go find one
sarcophagi have decorations on them mainly to protect the dead (medusa, sphinx...) and sometimes just to show off how much money one has
Well you need to collect the starfish from Poseidon's face, where all the statue of gods are. Then you just click use and the starfish will place itself on the little mantle, it will unlock the door. Same for Hades, the pomegranate, is above the sphinx, just collect it and do the same, except where hades is.
If a starfish loses all of its legs, they will grow back. This regeneration is asexual reproduction. We just learned about that
not necessarily, most people just find dead starfish washed up on shore and sell it. if fishermen find it caught in a fishing net, they throw it back into the ocean.

there mouths are on the bottom side of them with there suction cup moving things so they eat dead things just like scavengers.
Yes, as long as the starfish is still alive and both sides of the starfish have part of the center it can regenerate.
just like every christmas decorations
Just click use on the starfish very close to Poseidon's altar
No. Starfish appendages are known as arms, but they do have 'feet' (tubelike structures that enable the starfish to move).
just keep swimming
they are just decorations celebrating Christmas. the decoration resembles how joyus and merry Christmas is.
