They show a number of typical adaptations for aquatic life, such as dorsal orbits and nares and somewhat shortened limbs. |
This species has specialized scales, which are called ganoid scales, and it has nostrils or nares on tentacles that protrude from the head. |
The patient showed external minor abnormalities, including hypertelorism, small mouth, and anteverted nares. |
In Woodpeckers the cornua are enormously long, and curve over the skull, extending as far forwards as the anterior nares. |
However, the use of nares to detect pheromones is probably the most important type of chemoreception in fishes. |
At the time of transfer, the patient was again febrile with a new posterior nares hemorrhage that required packing and tamponade. |
