Product details
It’s not a squid. It’s 700 lights.
A firefly squid drawn in 700 lights, for a squid that makes its own blue light. The motto ends in a small ¹; the footnote underneath gives the proof and its source.
¹ Firefly squid make their own blue light, no borrowed bacteria, and each spring they crowd Japan’s Toyama Bay to spawn. Gimenez et al., Scientific Reports, 2016
Fig. 24 in The Small Print, Deep Planet’s series of animals drawn from their own true stories. For the one who lights up the room.
