Necropsy Summary – Differential Diagnosis From Gross Exam: Robust adult female with very worn teeth, late code 3, externally was looked much fresher than it actually was. There were clear line/net marks across the body which wrapped entirely around the body, with one long jagged line mark, with a few additional net markings posterior to the whole body wrap. There was no tissue reaction in the blubber under the line marks. Internally, the organs were extremely autolyzed, however the stomach and esophagus with very slightly digested fish, at least one whole rock fish/scalpen?. The lungs were extremely congested and bloody. There was a small region in the right uterine horn of abnormal glandular dark green/black tissue in the wall lining. It seems likely this animal died quickly, possibly from the entanglement event. Test Results: Final Diagnosis (only after results have been received): Final Diagnosis Code: History

Necropsy Observations: Please note general observations of color, condition, textures, etc. even when utilizing NA= not applicable, NE= not examined, NSF= no significant findings, NVL= no visible lesions. List weights (g) next to each organ examined. External Exam Body Condition: robust thin emaciated CBD Skin/Hair Coat (color, condition): Wounds/Scars:

A linear depression is present along the dorsal anterior side of the right pectoral flipper. Two patches of alopecia are present on the dorsal side at the fifth digit of the right pectoral flipper.

On the right side of the body, there is a linear depression extending the entire body just posterior to the pectoral flippers, and linear depressions at the mid-lateral right side of the body extending down to the anterior edge of the right pectoral flipper. An additional linear depression is present at the mid body on the right side.

A linear depression extends the entire width of the dorsum and wraps around the sides of the animal. There are two angles in that depression that are set 35mm apart.

A linear depression is present posterior to the left pectoral flipper. The origin of these depressions appears to be from line or twine gear.

Lesions: Parasites (found externally): Nostrils/Blowhole: NSF Mouth (tongue, teeth condition, ulcers)/ Mucous membranes (color): Teeth are very worn down. Otherwise NSF. Eyes (discharge, color, ruptures): Both eyes missing as a result of scavenging.
