Berthella caledonica is a species of sea slug, a marine gastropod mollusk in the family Pleurobranchidae.
This pleurobranchid was recorded by Jean Risbec at Orphanage Bay, Nouméa, New Caledonia beneath dead coral blocks, with three specimens observed at the time.
The species Berthella caledonica is currently distributed in the Indo-Pacific region in island territories such as New Caledonia, Australia, Hawaii, Okinawa, Marshall Islands and Réunion.[1]
Habitat
Berthella caledonica is usually a nocturnal species that can often be found in highly to moderately exposed rocky areas. It usually is situated at depths of 4–20 metres (13–66 ft) and during the day-time is often found in pairs under rocks in lagoons and reef flats.[2]
Size
Adults reach up to 50 mm in length; the internal shell measures about 18 mm, is thin, fragile, transparent and pearly, with an oval, slightly concave form and fine growth lines.[3]
