Its uptake by the pseudobranch and choroids gland may result in additional disturbance of some regulatory mechanisms (Khuhawar and Languani, 2000).
The pseudobranch has from 13 to 14 relatively thick filaments.
We euthanized all remaining fish to assess the following tissues by histopathology: bone (vertebra), brain, chromaffin tissue, corpuscle of Stannius, esophagus, eye, gallbladder, gill, heart, hematopoietic tissue, interrenal tissue, intestine, kidney, liver, nares, ovary, pancreas, peripheral nerve, pineal organ, pituitary gland, pseudobranch, skeletal muscle, skin, spinal cord, spleen, stato-acoustic organ, swim bladder, testis, thymus, thyroid tissue, urinary bladder, and gross lesions.
During copulation, sexual roles can be identified by the copulatory position, with the "male" being on the "female" shell, its head near the pseudobranch of his partner.
