The “hummingbird” bobtail squid is one of the most beautiful and colorful animals alive today. Its vibrant and iridescent coloration can change from moment to moment, as the bobtail squid has chromatophores in its skin that can expand and contract tiny pockets of coloration. Actually more closely related to the cuttlefish than to true squids, the bobtail squid is a sparkling gem on the seafloor, brilliant, beautiful and tiny. If you want to be flashy, fancy and colorful like our tiny friend the bobtail squid, get a bottle of Bobtail Squid Green™ ink.
