Flagellates live in a small-scale environment where viscosity impedes contact with their bacterial prey. Most flagellates use the active waving motion of a flexible flagellum with hairs to generate a feeding current. The presence of hairs significantly increases the force generated by the flagellum and also reverses its direction, hence...
The deep-sea glass sponge Euplectella aspergillum is well known due to its beautiful lattice-work structure, and has attracted interest in its solid and fluid mechanical properties. In a recent paper, we argue that including sponge tissue is key in understanding the hydrodynamics of these beautiful animals, and an analysis of their hydrodynamics...
Many protists take advantages of surface motility by utilizing microtubule-filled extensions to capture and handle prey particles. Some flagellates, e.g choanoflagellates, however, do not have these extensions, and the underlying mechanism responsible for prey transportation is unknown. In a recent paper, we investigate possible effects...
Pumping units in most sponges possess a gasket structure ensuring efficient pumping and filtration. However, some sponges lack such structure in their pumping units and it is an open question how they manage to pump and filter. In a recent eLife paper, we address this significant puzzle by demonstrating an unusual flow pattern that accomplishes...
We welcome new faces at the Centre for Ocean Life!
Choanoflagellates are filter feeders and an important component of microbial foodwebs. Because they are theancestors of multicellular life, they have been intensely studied. Some species build an elaborate external ribbon structure. Its function is unknown but we demonstrate that it may significantly increase prey capture efficiency...
