What is digestion and why is it important?
Digestion in the Angler Fish:
The Angler has a light attached to its head. This light producing organ is called a photophore and is produced through a chemical process called bioluminscence. This light attracts the prey for the Angler. Anglers are carnivores. They can even swallow fish up to twice their size because of their distending jaw and expandable stomach. In most bony fish, their stomachs are generally shaped. When the prey gets close, the Angler uses it's VERY sharp teeth to trap the prey by putting their teeth in an angled position. After they chew up the fish and it gets broken down in the mouth. The teeth help the food get mechanically broken down. Anglers also have a large tongue that aids in mechanical digestion as well. Enzymes help mechanically break down food. The food then gets moved to the Pharynx. After the Pharynx is the esophagus which is a muscular tube. The esophagus is lined with mucus and strong muscles that keeps the food lubricated so it will have an eaiser time getting down. Then it goes to the gizzard, the stomach, the Pyloric Cacea. The Pyloric Cacea is an organ that helps fish digest foods by both mechanical and chemical digestion. After this, the food goes to the rectum, pancreas then liver. All of the energy from the food gets diffused into the cells and that is how our critter gets its food!
