Really sad to report that our friend and colleague Richard Fortey passed away this morning after a short battle with cancer. We’ll all miss his wit and wisdom. Here he is checking out a dino footprint we found while filming together on the Isle of Wight

Limpets are the BEST gastropods. This is not an opinion, it is evolution. Limpets evolved more than 50 times: they are important. People in Hawaii already know this.

Glaucus atlanticus is like a living Pokemon.

It is NOT in the deep sea, Glaucus lives on the surface, but it still got the cover of this ridiculous book of "deep sea girls". Which was published here

Arctica islandica is one of the oldest (non-colonial) animals, they easily live more than 500 years, and still look amazing. It got a write up in "Mollusc World" (this is a real magazine) that you can read here

Xenophora conchyliophora (not the auto-correct "xenophobia" - boo!) is an ace decorator. I have never seen one alive. In their natural habitat they are INVISIBLE.

Evolutionary history of molluscs was contentious for decades due to conflicting genetic data vs morphology and fossils. Our tree resolves previous controversies; also provide key insights on what the ancestral mollusc looked like!
