spiracular

It can also be distinguished by its large spiracular papillae.

There is a white spiracular stripe that runs the length of the body.

The spiracular line is broad, dark reddish brown, edged below with yellow or red.

There is a pale spiracular stripe edged above by purple.

Spiracular buttons are present in the premature third instar.

A spiracular chamber is present, but the spiracle is closed and never opens during development.

The supposed functional advantages of spiracular gills and the reason for their evolution are critically considered.

The spiracular openings of the respiratory system are restricted to a pair each (Amphipneustic).

Circular spiracular plates can be found separated by about one plate's width in the posterior area.

The caterpillar is blackish-brown with a red spiracular line with white dots.

There is a dark green subdorsal line, and yellowish grey spiracular line.

An internal closing apparatus involves the spiracular tracheal wall and has a single opening muscle.

During the open phase, spiracular muscles relax and the spiracles open completely.

Marked individuals usually have dorsal and spiracular silvery stripes.

Likewise, the third instar larva has 3 larger spiracular slits on each side.

They are green, often darker ventrally or sometimes dorsally, with a whitish spiracular line.

A pale yellow subdorsal line and an almost white spiracular line are the only markings.

The curve in the spiracular slit at the middle verified that the species was M. stabulans.

The more derived groups bear a plurality of spiracular openings on their sides, and are termed the Pleurostigmomorpha.

Spiracular plate: Subcircular, greatest diameter about 0.14 mm.

Along with the spiracular chamber, this feature in Panderichthys can be considered transitional during the evolution from fish to tetrapods.

The spiracular line is dusky but not conspicuous, and the spiracles are blackish surrounded with yellow.

Females also have a spiracular plate, located on the underside of the abdomen near the lungs, shaped like an oval.

These are usually more or less horizontal, parallel and usually bear branched spiracular hairs in four tufts.

The trend from the early sarcopterygians to the first tetrapods was an increase in the size of the spiracular chamber and its opening to the outside.
