Angaria nhatrangensis is a species of sea snail, a marine gastropod mollusk in the family Angariidae.
Description The shell can grow to be 35 mm to 65 mm in length. It has a depressed apex, pentagonal whorls with peripheral rows of spines, and numerous spiral ribs. The shell is dirty white to light greenish with bright pinkish-red spiral cords and purplish-red colouration inside the umbilicus. The aperture is round and nacreous inside.
The species is distinguished from the similar Angaria neglecta by its coarser spines and pink-red spiral colouration, and from Angaria delphinus by its colour pattern and larger spines.
Distribution Angaria nhatrangensis can be found off of Vietnam. According to Deller, they inhabit rocky substrates at 5-10 metres depth and are known only from the Nha Trang region of central Vietnam.
