Costasiella is a genus of sacoglossan sea slugs, a shell-less marine opisthobranchid gastropod mollusk in the family Costasiellidae.[2] The Costasiella is defined by some specific characteristics such as smooth rhinophores which are usually simple with dull tips and flattened at their base.[3][4] Other features include rounded, tentacular anterior foot corners that exhibit their spatulate shape to enhance mobility and blade-shaped radular teeth with substantially short bases.[3][4] Most of the genus could be found within the tropical and subtropical regions of the Western Pacific oceans.[4] Their preferred habitats include areas of soft, muddy sediments around intertidal zones.[3][4] Their diets vary from species to species but generally consume various types of green algae, more commonly the Vaucheria and Avrainvillea.[3][4]

The most recent diagnosis of the genus Costasiella is by the Dutch malacologist Cornelis Kees Swennen (2007).[4]
