Dead things, we know, stink. Dead things that live in water stink more. Dead things that live in seawater stink more. And I think echinoderms may be the top of the list.
We have a new seawater tank, which I've been looking after. Unfortunately, had a water quality problem and a lot of animals in it died. But the sea cucumbers were really wretched things to clean. Now I can tell my student Sakshi that it's not just starfish that die horribly in an awful mess.
My hands are very itchy and dry from having been in salt water much of the day.
