Polyplacophora. This class is made up of chitons, marine creatures that live under rocks. Their shells are made up of eight plates, protecting them while also allowing them to flex upwards or curl into a ball.

Pteriomorphia. This subclass is made up of bivalves with large gills used for feeding and rudimentary photoreceptors. Memebrs include mussels, scallops, oysters and pen shells

Blue-Green Chiton (Chiton glaucus)

Family: Typical Chiton Family (Chitonidae)

IUCN Conservation Status: Unassessed

Like other chitons, the Blue-Green Chiton is a heavily armoured eyeless mollusc related to marine snails which relies on its strong aragonite-based shell to defend it from potential predators as it slides slowly along on a frilly "foot", clinging to surfaces beneath it as it travels using a layer of thin-yet-sticky mucus and the suction-cup-like shape formed by the foot's frilly rim. Although they lack any conventional eyes, the 8 armoured plates of a chiton contain numerous lens-like structures (also made of aragonite) which focus light onto a retina-like membrane, allowing the chiton to perceive light and possibly basic shapes above them in order to identify potential predators, giving them an opportunity to grip more tightly onto the surface beneath them to prevent them from being flipped over to expose their unarmoured underbelly (although if this does happen they are also able to curl up in order to leave as little of their foot exposed as possible.) Found in coastal and estuarine waters surrounding New Zealand and Tasmania, Blue-Green Chitons spend much of the day concealed in rocky cracks or under large stones and emerge at night to feed, using a spiny tongue-like structure that extends from their tiny downwards-facing mouths to scrape algae off of the rocks beneath them. The name of this species refers to the variety of colours seen on the shells of different individuals; while typically dull green, individuals with blue, yellow or pale brown shells are also frequently reported.

Polyplacophora or Chitons

Chitons are one of the lesser-known members of the Mollusca phylum. They have an incredibly muscular foot on the underside of their shell that allows them to stick tightly to rocks as well as curl themselves up into a ball like an armadillo!

Chitons snuggled between the rocks for moisture

These creatures, which at first may be mistaken for barnacles or oysters, are a type of primitive mollusc, with fossil records dating back 400 million years ago.

Their appearance is quite odd, with a series of plates running down their backs, and a tough tissue surrounding them. If you were to detach one of these creatures from a rock (a very hard feat mind you), you’ll notice the underside is quite similar to that of a limpet snail.

Although the specimens pictured have a rather dull appearance, there are species of chiton that are quite colorful, like the Flame-lined Chiton.

Unidentified, Family Chitonidae

Did you know that Chiton (specifically the wandering meatloaf chiton) produce the hardest known biologically made material? Their shells are also covered in microscopic lenses that combine to almost make their body into one compound eye. Why they need to look so much, who knows?
