Off Japan and South Africa, myctophid fishes predominate. Prey may range in size from 60 to 300 mm and include a wide range of species, including some crustaceans such as shrimp. In captivity, the mean feeding rate of a striped dolphin is 3.45 kg of fish a day.Striped dolphins may dive to depths of 200 m when foraging. In the eastern tropical Pacific, these dolphins are occasionally found with yellow fin tuna in possible foraging aggregations.
Boerhaave's syndrome. a condition marked by spontaneous rupture of the esophagus, usually preceded by severe vomiting, leading to mediastinitis and pleural effusion. Clinical manifestations are violent retching or vomiting. Emergency care with surgery and drainage is needed to save the life of the patient.
The syndrome is commonly associated with the consumption of excessive food and/or alcohol as well as eating disorders such as bulimia. The most common anatomical location of the tear in Boerhaave syndrome is at left posterolateral wall of the lower third of the esophagus, 2â3 cm before the stomach. Currently, the most common cause of esophageal perforation is iatrogenic. However, iatrogenic perforations, while still constituting a serious medical condition, are easier to treat and less prone to complications, particularly mediastinitis and sepsis.
