Doto cuspidata may reach a length of 25 mm. The body color is light brown or beige. The cerata are swollen and organized in one row on each side, like most Dotidae. The cerata have grey tubercles and lacks the pigmented spots of the Doto pinnatifida.
The Doto cuspidata usually feed on hydroids, like the rest of the Dotidae family members. It can be found from well below the tidal zone and down to 300 meters depth.
It is registered in Norway and on the British Isles.
The Dotidae family is currently not assigned to any particular infraorder within the Dexiarchia suborder. Genetic studies will hopefully sort this out for us. In the meantime, seawater.no present the Dotidae species together with Dendronotidae and Tritoniidae, simply by tradition.
