Trinchesiidae Nudibranchs are brightly coloured aeolid nudibranchs, and in keeping with other members of this group, Trinchesiidae species have many tapered blood-filled tubes called 'cerata' growing on both the back and side areas of the body.
The cerata are thin-walled, blood-filled tubes which perform several functions, as part of the digestive system and also a gill-like function. The diet can influence the colour of the cerata and as such, members of this family can have varying colours, depending on the diet.
