Sagartia Time Lapse Sea Anemone

One hour of compressed eating time for sea anemone sagartia.
In the appropriation of food, the parts chiefly concerned are the five
following: the tentacular gland cells whereby the tentacles are rendered
adhesive for food, the tentacular muscles by which the tentacles are
pointed toward the mouth, the tentacular cilia by which the food is
delivered from the tip of the tentacle to the mouth, the transverse
mesenteric musc'es whose action opens the mouth, and the oral cilia
(lips and oesophagus) whose reversal in the presence of food carries
this material into the digestive cavity of the sea-anemone. Of these
five parts the mucous cells, the tentacular cilia, and the transverse
mesenteric muscles are so uniform in their action that they need no
further consideration. The oral cilia and the tentacular muscles on the
other hand are much more open to variation and hence may serve to
indicate to some extent the condition of the animal as a whole.
