The thorax is 2 cm (0.8 in) in diameter, its sides distended when compared with the thorax of other Australian cicadas.

Many have no wings or ocelli, and may have a different shape to the thorax.

This also remains a significant element of the jaw in some primitive bony fish, such as sturgeons.

In some bony fishes, for example certain Protacanthopterygii and Gadidae, the mitochondrial control region evolves remarkably slowly.

Being less developed, the thorax of an adolescent is likely more prone to this injury given the circumstances.

With a maximum published length of and weight of ., it is one of the largest marlins and also one of the largest bony fish.

Much like a spider, the body of a solifugid has two tagmata an opisthosoma (abdomen) behind the prosoma (that is, in effect, a combined head and thorax).

Within cartilaginous fish, approximately 80 of the sharks, rays, and skates families survived the extinction event, and more than 90 of teleost fish (bony fish) families survived.

The first segment of the thorax is small and narrow, while the second and third are larger and broader, especially in the males, where they include the flight muscles.

These problems may directly affect the extra ocular muscles themselves, and may also result from conditions affecting the nerve or blood supply to these muscles or the bony orbital structures surrounding them.

The tumor cells always stay on the outside of the nerve, but the tumor itself may either push the nerve aside and or up against a bony structure (thereby possibly causing damage).

Mutations of SDHB play an important role in familial adrenal pheochromocytoma and extra adrenal paraganglioma (of abdomen and thorax), although there is considerable overlap in the types of tumors associated with SDHB and SDHD gene mutations.

It is the greatest transition that we have, actually, on land from one habitat to another, bar none, to understand how a bony, fairly heavy, kilogram or a couple of kilogram animal could make such a transition.

Members of the order are notable for having toothed or bony tongues, and for having the forward part of the gastrointestinal tract pass to the left of the oesophagus and stomach (for all other fish it passes to the right).
