lamella

But the disk couldn’t suction with individual lamellae, making it vulnerable to falling off.

It has no sticky lamellae on its feet for wall climbing, it has blinking eyelids, it tends to be more docile around humans.

Then liquid drains from the thin membranes, known as lamellae, that encase the individual bubbles until one of those lamellae thins too much to support the bubble.

The disc is supported by a complex series of muscles and bones that create suction by erecting and depressing the lamellae.

Gills or branchiae may be developed by parts of an appendage becoming thin-walled and vascular and either expanded into a thin lamella or ramified.
