into the stomach, in which it is mixed with the digestive 
juices from the digestive gland and pancreatic czeca. 
It may be noticed that the anus is not at the hind end 
of the body, but the intestine is bent forwards along the 
under surface till the whole alimentary canal is U-shaped, 
with a ventral flexure.

In its natural position, the cuttle rests suspended in the 
water near the surface with the body horizontal, the tentacles 
Motor. hanging loosely downwards, the two long ones 
* being coiled up inside the others. A forward. 
swimming motion is caused by undulations of the two lateral 
fins. A powerful backward jerk is produced by forcible 
ejection of water through the siphon. There are special 
muscles for moving the tentacles and the eyes.
