costal groove

Both species have 12 or 13 costal grooves visible from the side.

They have four tiny legs each with three toes and an average of 62 costal grooves.

The under surface is smooth, and destitute of a costal groove.

The eleventh has a slight angle and a shallow costal groove.

Typically the yonahlossee has 15 to 16 costal grooves.

Typically, specimens will have 12-14 costal grooves.

The adult form is pinkish white, sometimes with traces of orange on its tail, feet, and sides, and has 16-19 costal grooves.

The salamander has 12-13 inconspicuous costal grooves.

There are 14-16 costal grooves, counting those in the fore limb and hind limb regions.

There are between eighteen and twenty-one costal grooves, conspicuous in appearance, lending a worm-like character to this species.

The tail is about the same length as its body, which has 17 to 19 costal grooves (vertical grooves along its sides).

In herpetology, costal grooves refer to lateral indents along the integument of salamanders.

There are twelve to fifteen costal grooves on either side of the body and the tail is prehensile and has a constriction at its base.

Terrestrial mole salamanders are identified by having wide, protruding eyes, prominent costal grooves, thick arms, and rounded tails.

The costal groove is a groove between the ridge of the internal surface of the rib and the inferior border.

The siren has only one gill slit, a finned tail (tip compressed), costal grooves, and three toes on each of the two front feet.

The twelfth has no angle nor costal groove; it is much shorter than the eleventh rib, and its head is inclined slightly downward.

The internal surface, smooth, and concave, is directed downward and a little inward: on its posterior part there is a short costal groove.

It has two naso-labial grooves joining its nostrils to its mouth and sixteen costal grooves down its flank.

Salamandrids are distinguished from other salamanders by the lack of rib or costal grooves along the sides of their bodies and by their rough skin.

Between the nostrils and the mouth it has a pair of naso-labial grooves which are involved in chemoreception and it has sixteen costal grooves on either side of the body.

Tiger Salamanders and Idaho Giant Salamanders have superficial resemblance pertaining to size and shape, but the costal grooves and foot tubercles are significantly different between the two species.
