Invertebrates are among the most abundant creatures on the planet - they include over 98% of all known living species. Invertebrates are animals without backbones, instead some have an hydrostatic skeleton, like the jelly fish or worm, while others sport a hard outer shell, like insects and crabs.

Currently we are featuring the following slough invertebrates:

Fat Innkeeper
Worm
