a cartilaginous tumour
However, the exoccipital-opisthotic is fully formed, with no indication of a substantial cartilaginous component.
If so, the major electrosensory ascending system in cartilaginous fishes would resemble that in the ray-finned fishes, as discussed below.
However, their use is restricted largely to tongue and pharyngeal-wall function, given that most of the alimentary canal is shielded by bony or cartilaginous structure impervious to ultrasound waves.
The degree to which the diencephalon is elaborated varies considerably across cartilaginous fishes, however, making comparisons and the identification of nuclei within particular species somewhat challenging.
In cartilaginous and ray-finned fishes, laterally migrated nuclei of the latter give rise to ascending sensory projections to the pallium, mimicking those from the dorsal thalamus.
Because cartilaginous fish do not have bone marrow, the spleen and special tissue around the gonads produces red blood cells.
Cooking cartilaginous meat in the stew will result in gelatin being dissolved into the broth.
In cartilaginous and lobe-finned fishes and also in amphibians, a more complex structure is present, with the cerebrum being divided into three distinct regions.
