Last week I gave you this mystery object to have a go at identifying:

Clearly it’s some kind of sea-star, but there are a LOT of different species .
Remarkably, that doesn’t seem to have posed a problem. The five stumpy arms narrowed it down to one of the cushionstars or biscuitstars and it seems that was more than enough for some of you.
Salliereynolds flagged one of the diagnostic features and dropped a hint to the species name:
“Six lumps to a side? From down under?”
But Goatlips took the mystery object to a whole new level with a biscuit recreation:
This specimen is a Southern Biscuit Star Tosia australis Gray, 1840. Probably not as tasty as an actual biscuit, but certainly very biscuity in appearance.
A short answer today I’m afraid, but it’s been a difficult week and there’s a lot to do in the Dead Zoo this Friday!
