Vídeo about the charismatic pelagosphera larva of sipunculids.
The sea biscuit metamorphosis image that I submitted for the Node’s intersection image competition was selected for the November calendar! You can download it here.
Metamorphosis is a dramatic life-changing event for many invertebrates. It’s the intersection between two distinct lives – larval and adult. It is how a caterpillar becomes a butterfly.
The process is fascinating, specially when you have the chance to see it happening with your own eyes. You too can see it in the video A Sea Biscuit’s Life.
Recently the community website the Node from The Company of Biologists announced a thematic image competition. The images needed to be related to developmental biology and some sort of intersection.
Because intersection is essentially another word for metamorphosis, I submitted a photomicrograph of a metamorphosing sea biscuit from my master’s thesis research. It made it to the final and was a runner-up!
My video about the life cycle of a sea biscuit is now online!
