Characteristics
Adult sand isopods are horizontally flattened.[2] The thorax is almost round from above and the long, robust legs with large setae. The abdomen is short and pointed. Sand isopods reach 15 mm (0.59 in) long and 7 mm (0.28 in) wide. They use the last pair of legs to dig tunnels in sand. When removed from the tunnels (for instance, by wave action), sand isopods swim down to the substrate, where they dig underground again.
Ecology
C. coeca feeds on carrion, which it holds with its gnathopods while chewing pieces off with its mandibles.[3]
gollark: This is not too difficult, I think it took me about 30 minutes.
gollark: If you were to do it from scratch it would also require setting up Grafana and Prometheus.
gollark: I basically just had to write 20 lines of bridge code (into my existing random stuff webserver) and add some code to the computers running stuff ingame.
gollark: Not very much as I had the majority in place already.
gollark: You don't need a domain whatsoever for this, but it's nice and quite cheap.
