Anteaeolidiella cacaotica (Stimpson, 1855)
Maximum size: 21 mm (Kay,
1979).
Identification:
This
species has closely spaced rhinophores and laterally directed cerata.
The body is translucent-orange, usually with faint white markings on the
notum. The cerata have
prominent cnidosacs in their tips and usually have irregular, white
subapical bands. The rhinophores and cephalic
tentacles usually have white tips.
Natural history: On
Maui, Anteaeolidiella cacaotica
is a moderately rare species found from the low
intertidal to a depth of 15 m (49 ft) in protected to moderately protected rocky areas and in Halimeda
kanaloana beds. However, it may be more common in the low
intertidal on Oahu (Bertsch and Johnson, 1981). It lays white spiral
egg masses composed of a
"kinked" ribbon. The eggs hatch in 5-7 days in tanks where they feed on Exaiptasia sp. (Note 1).
Distribution:
Big Island, Maui, Oahu and Kauai: widely distributed in the Pacific.
Taxonomic notes:
This
is
the species listed as Aeolidiella takanosimensis in Bertsch &
Johnson, 1981. It's also listed as Aeolidiella takanosimiensis in Kay, 1979 and Gosliner, 1980. Some sites list it as Anteaeolidiella indica or Aeolidiella indica. It was
first recorded in Hawaii from Poipu, Kauai by Allison Kay in Jan., 1965.

Observations and comments:
Note
1: Daniel Jennings-Kam observed multiple animals feeding on Exaptasia
sp. and laying egg masses over a three week period in the exhibits at
the sea life park in Waimanalo (June-July, 2023). On Oct. 12, 2023, he
reported that: "...I have had several batches of eggs hatch and
settle into little slugs! It takes about 4 weeks for the egg mass to
hatch and the first little slug to be spotted settled out. I raised them
how people raise Berghia in the hobby aquarium, basically a closed system with stagnant water with some Exaptasia for food."
