Philinopsis gardineri (Eliot, 1903)
Philinopsis gardineri is often confused with the highly variable P. cyanea and sometimes even with Chelidonura varians. The most distinguishing
feature is its round, rather than truncate anterior body margin and
especially the protruding bubble shaped head, which some of us have compared
to the front end of a Boeing 747.
P. gardineri has a blue line around the mantle margin and on the foot. P.
cynaea which has the truncate body shape, usually has brown markings, while
C. varians has a blue line down the center of the body.
This species which was originally described from Tanzania, has now been
recorded throughout the Indo-Pacific from South Africa to Indonesia, New
Guinea, the Philippines, Fiji, Guam and the Marshall Islands. While I
would expect the species to occur also in Australia, the only reference I
could find for that locale was Debelius(1996).
Cephalaspidean opisthobranchs feed on a variety of prey from filamentous
algae to flatworms, polychaetes and other opisthobranchs. According to Coral Reef Animals of the Indo-Pacific ,
P. gardineri is a member of a
species complex whose members probably feed upon polychaete worms.
Specimens attain 4 cm in length and are most often observed on soft

I now have dates for my year 2000 Tiata Milne Bay trips
Trip # 1 Feb. 1 to Feb. 14
Trip # 2 Feb. 15 to Feb. 28
Trip # 3 May 2 to May 15
Trip # 4 May 16 to May 29
All trips are 13 nights aboard Tiata with 12 diving days. I will be
along on all four trips. (Lucky me!).
You will arrive in Alotau from Port Moresby at 4pm on the first day
of the trip and be met and transferred to the boat by the Tiata crew.
On the last day of the trip you will depart for POM on an early morning
flight, connecting the same day with your international flight.
Price is $4400 U.S. per person. You make your own airline
reservations with the travel agent of your choice. I will tell you
exact dates and flights for travel between POM and GUR. I have prepared some information about PNG, Tiata and
the diving which I will be happy to mail to you if desired.
Please let me know your interest in this trip. If you wish to
secure a place, send me a deposit of $1400/person. Checks should be
made out to "Mary Jane Adams." Write your trip number on the check.
Balance will be billed as two installments of $1500 each.
Refund policy: I will not be able to refund payment unless a
replacement can be found.
I am looking forward to another great year of diving in Milne Bay
and I hope all my best buddies will be joining me.
