Tenellia sp. 56 Undescribed
This aeolid nudibranch is very long and narrow in the body with matching long thin tubular-shaped cerata. The cerata are sparse and appear to arise singly from the lateral dorsum. The propodial tentacles are undeveloped being only bluntly formed. The head bears a white patch between the rhinophores and oral tentacles. The oral tentacles are bright orange with a watery orange tip, the rhinophores are translucent white at the basal 1/3rd, creamy yellow to the middle 1/3rd and bright orange for the distal 1/3rd with a watery orange tip. The body is translucent white with the viscera and acini visible within. The aforementioned cerata are the same colour as the body with the distal 1/3rd being a faint creamy yellow. The digestive diverticula are not visible within the cerata.
