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]

<i>Costasiella ocellifera</i> Species of gastropod

Costasiella ocellifera is a small (5–13 mm) species of sea slug, a shell-less marine gastropod mollusk in the family Costasiellidae. Costasiella ocellifera, and other members of the Costasiellidae family are often mistakenly classified as nudibranchs because they superficially resemble other species of that group, but they are actually a part of the Sacoglossa superorder of sea slugs, also known as the “sap-sucking sea slugs,” "crawling leaves" or the "solar-powered sea slugs." C. ocellifera was discovered by Simroth in 1895, and was initially classified as Doto ocellifera. The Brazilian species, Costasiella liliana, is a synonym of C. ocellifera.Costasiella ocellifera shows long-term retention of functional kleptoplasty.

<i>Costasiella nonatoi</i> Species of mollusc (sea slug)

Costasiella nonatoi is a species of sacoglossan sea slug in the genus Costasiella. It is one of few species in the genus that is not photosynthetic. The description of this species was based on two specimens which were serially sectioned and designated as the holotype. The species was named after Dr. Edmundo Nonato, a professor at the Oceanographic Institute of the University of São Paulo.
