Any idea? Flat slug like thing...

Hi chaps, Any ideas please? Friend or foe? It’s about 2.5” long 1.5” wide and 3/4” thick, it’s more of a mottled green/ greyblue colour. Ive just spotted it for he first time, sorry about pics my lights have just gone into moonlight, hence the overblue hue

Some type of limpet I think

Thx but It’s soft, and moves, very slowly, I thought limpets had a hard shell?

 

[Crabs McJones]

Hmmm. Can you pull it and get some better pics in a container?

When I gripped it gently with tongs it really gripped the tank, I didn’t want to pull harder in case it released toxins

Could be a cuke of some sort but it does look like a limpet...

A couple of things in my mind.

Sea hare: Unlikely given perfectly oval shape
Marine Pulmonate: Shape is similar; unlikely since they are air breathing and found in the intertidal
Limpet is my best guess but I don't really know what you mean by soft until I see it

 

[Crabs McJones]

Possibly a fleshy limpet, they'll appear squishy but have a hard undershell, the hole in the top is what's making me think it has to be a limpet of some sort

Chiton maybe?

Chiton maybe?

Chitons are segmented

I’d not heard of fleshly limpets, could be a good call, hopefully I’ll see him again today and can get a better picture under daylights, I’m assuming a limpet is reef safe

Except key hole limpets and scutus...they are known to munch on sps occassionally.
