fuscus present morphological adequacy for both herbivorous and omnivorous feeding habits. The estimated mean intestinal coefficient and characteristics of the digestive system of S. The anterior intestine presents folds similar to those of pyloric caeca. All must find food and protect themselves from predators. At high tide, animals and plants must survive waves rolling in or crashing down. As the ocean water retreats at low tide, marine life must withstand hours exposed to the air or in shallow pools. The intestine is long and thin with four folds around the stomach. A whole host of fascinating plants and animals survive in this rugged, changing seascape. Between the stomach and intestine, there are three pyloric caeca. The transition region close to the stomach shows plain and striated muscular fibers. Mucous glands are predominant, and the muscular layer of the esophagus presented striated fibers all along its extension. Animal Info Animal InfoBooks Animal Bytes. Invertebrates are a diverse group of animals including many phyla and. The esophagus is short with sphincter and thick distensible wall with longitudinally folded mucosa. Explore in-depth details about tide pools and discover why these ecosystems are important to our planet. Most of the animals in the tide pool are invertebrates - animals without backbones. fuscus is composed of the tunica mucosa, tunica muscularis, and tunica serosa. This study investigated the morphohistology of the digestive tract and the mean intestinal coefficient of the damsel fish Stegastes fuscus captured from the tidal pools of Northeastern Brazil.
