Banded Sea Snake Laticauda colubrina on a outer reef swimming to surface, looking for fresh water. Sea Snakes need to drink fresh water and regularly come onto land for that purpose. The Banded Sea Snake Laticauda colubrina occurs in tropical Indo-Pacific. Males maximum length 88 cm, females 142 cm. The Banded Sea Snake is often seen in large numbers in the company of hunting parties of giant trevally (Caranx ignobilis) and goatfish. Their cooperative hunting technique is similar to that of the moray eel, with the Snakes flushing out prey from narrow crevices and holes. \nThis specimen was encountered in the Triton Bay, Kaimana Regency, West Papua Province, Indonesia, 3°55'0.7321 S 134°6'7.7298 E.

Blastomycosis is a fungal infection caused by inhaling Blastomyces dermatitidis spores. If it involves only the lungs, it is called pulmonary blastomycosis. Only about half of people with the disease have symptoms, which can include fever, cough, night sweats, muscle pains, weight loss, chest pain, and feeling tired.

A thousand or more years ago, natives inhabited the lower elevations around the San Francisco Peaks of Northern Arizona. In an area so dry it would seem impossible to live, they built pueblos, harvested rainwater, grew crops, hunted game and raised families. Today the remnants of their villages dot the landscape along with other artifacts such as this obsidian projectile point from the Sinaguan era; about 500AD to 1450AD. Although commonly called an arrowhead, the point was probably not attached to an arrow or shot from a bow, a weapon not thought to be used by the Sinagua. More likely it was affixed to the tip of a spear and thrown to strike and kill game animals. It is unlawful to remove artifacts, such as this point, from a native site. They may be examined but must be returned to their original location. This projectile point was photographed at Sandy Seep in the Coconino National Forest near Flagstaff, Arizona, USA.

Myxoid liposarcoma.  Myxoid/round cell liposarcoma, or MRCLS, is one of several types of liposarcoma. Liposarcoma is a rare cancer that grows in the cells that store fat in the body. MRCLS usually grows in the arms and legs. These tumors grow slowly, and they can spread to other parts of the body
