Abdomen

[cerivs]

We don't have the term abdomen....seems odd to me. Seems like it should be distinct from and a part of the trunk. -Amy

is_a organism subdivision.

The ventral subdivision of the trunk that contains the visceral organs.

Start at about the same time as visceral organs

Consider adding peritoneal cavity too.

Are you sure about the ventral qualifier? I'm not sure about fish subdivisions but a typical scheme is trunk = thorax + abdomen. E.g. in FMA the lumbar vertebra is in the abdomen (I know 'lumbar' isn't used as a vertebral subdivision is fish but I think broad divisions like 'abdomen' should be consistent)

In adults the rostral-ventral area might be considered the thoracic area. I think the curator in question was thinking in embryos. The heart is immediately under the branchial arches and is almost in the head. Even in older fish the heart is more rostral than in mammals.

Would the wording vetro-caudal portion of the trunk be more acceptable

Older fish note heart is abutting gill arches.

Attached is an image of the abdominal areas of younger and older fishes.
