Chelidonura(?) sp. #4
|Maximum size: 30 mm.
species is superficially similar to Chelidonura fulvipunctata.
its white patches are more diffuse, it lacks any sign of longitudinal
lines and it lacks a central orange spot on the front of its head. It
also reaches a larger size and has a more elongate internal shell with
a larger protoconch and no brown tint at the apex.
Natural history: Chelidonura(?) sp. #4 is
a rare species found in moderately exposed rocky habitats. It is known
from tide pools and subtidally to 15 m (50 ft). It shows a nocturnal
pattern when held in a dish and, unlike C. fulvipunctata, produces
extensive defensive mucus when handled.
Oahu, Maui and Lanai.
This species was first
recorded in Hawaii from Maliko Bay, Maui by PF on May 23, 1992. Ortea, et. all., 2014 lists it as a Chelidonura, rather than a Navanax,
presumably based on shell form. However, they find multiple clades
within that genus. So, we're leaving a "?" after it, pending further
