Box jelly (with fish inside) at the Lilipuna Pier last night

Last night, after trying out some new light traps for our night plankton labs, we stopped by the spotlight on street side pier.
Light traps for plankton
We were looking for the big worm mating event mentioned to me that day by Heather Ylitalo-Ward (thanks Heather). Indeed the worms were there in good numbers:

Even better though, were the swarms of other creatures, including several box jellies. These are not the same species (type) as the ones that close the beaches in Waikiki. Looks like the species I remember as Carybdea rastoni, but I will see if I can collect more and send them off for identification.

These smaller box jellies come up at night to feed on the night plankton and associated animals. Jerry Crow and I used to collect these off of Kewalo. Note the two small fish in the bell of the box jelly. They were able to swim in and out of the jelly - like it was their own personal diving bell - with armament - how great is that!

Aloha,

Zoanthids

You may recognize these critters from the No-Touch Table.  These anemone-looking animals are called zoanthids, stemming from the order zoanthinaria.  Belonging to the phylum cnideria, zoanthids are loosely related to corals and jellies.  In fact, zoanthids are soft corals.


When most people think about coral, one of the first things that comes to mind is a colorful, tropical coral reef.  The grand majority of a reef is composed of coral skeleton.  Unlike the stony or hard corals, zoanthids are soft corals which lack an internal limestone skeleton.  Instead of having a rigid internal skeletal structure, their bodies are tough and leathery.


Being cnidarians, zoanthids fall under the same phylum as corals and jellies.  One characteristic that all cnidarians share is the ability to catch prey using stinging cells called nematocysts.  The sting of some nematocysts can be excruciatingly painful.  The sting of a zoanthid, however, is benign to humans.  To compensate for their stinging short-comings, certain species of zoanthid can secrete toxins as a deterant.
 One species of zoanthid, Palythoa toxica, produces polytoxin, one of the deadliest toxins known to man.  Ancient Hawaiian warriors of Maui would tip their spears with polytoxin to ensure the wounds they inflicted would be deadly.

Not all zoanthid species are toxic.  It was thought that the species being sold for home aquariums where all of the non toxic variety.  In a publication from 2011, researchers tested zoanthids being sold from home aquarium stores within the United States.  Zoanthids containing the deadly polytoxin were found in three aquarium stores in the Washington DC area.
These incidents of toxic animals in a retail setting may be due to mistaken identity.  Zoanthid species can be extremely difficult to distinguish from one another.  Even deciphering between the genera of Palythoa and Protopalythoa can be nearly impossible without DNA analysis.  This is why our green zoanthids are residing in the No-Touch Table.

They are green.  They are zoanthids.  We think they are Protopalythoa, but we aren't taking any chances.
For more information about the toxic zoanthids found in home aquarium stores, follow the link below.

Aloha,

Leon

Star Scientists

In the past week two researchers at HIMB appeared in articles of the Star Advertiser. Brian Bowen landed on the front page of Saturday's (6/8/13) paper in an interview for the article, "Research traces lineage of sea life to Hawaii waters." Bowen discusses his recently publish findings on species dispersal from Hawaii. Being isolated islands in the middle of the Pacific Ocean, it was assumed that species that evolved here wouldn't branch out and establish populations in other parts of the Pacific. By analyzing DNA from 25 different species, scientists were able to identify five species that had ancestral ties to Hawaii. These five species include the Yellow Tang (Lauipala/Zebrasoma flavescens), the Hawaiian pink snapper (Opakapaka/Pristipomoides filamentosus), the bullethead parrotfish (Uhu/Chlorurus spilurus), the ember parrotfish (Uhu/Scarus rubroviolaceus), and the black seacucumber (Loli/Holothuria atra).

Greta Aeby was interviewed for the "Fish's skin disease still a mystery" article (6/11/13) wherein she discussed the coral disease outbreak on the North Shore of Kauai.  The article focused on a skin disease of the Hawaiian white-spotted toby fish (Canthigaster jastator), but gave generous attention to Aeby's research efforts.  Large blooms of cyanobacteria, also known as blue-green algae, are affecting the coral in the areas being surveyed.  This disease is a serious threat to the reef.  Fortunately the disease can be effectively slowed by applying marine epoxy directly to affected corals in a similar manner to a fire line.  The epoxy kills the coral directly beneath it and the encroaching disease is cut off from the healthy coral on the other side of the epoxy quarantine.

A Brief History of Moku O Lo‘e — “Coconut Island”

and some of the surrounding reefs (photo: B. Daniel).
Soon after his arrival in 1908, University of Hawai‘i’s first president John W. Gilmore noted that "our teaching should be in accordance with the environments." He proposed the creation of a marine biological laboratory. A laboratory was established in 1912 in a wooden structure on the shores of Waikiki with funds from the Charles M. Cooke Estate. This lab functioned in association with the Waikiki Aquarium. In 1919, both facilities were turned over to the University of Hawai‘i. In 1947, the late Edwin W. Pauley provided an opportunity to establish a marine laboratory on Coconut Island, and the marine sciences entered into a new era in Hawai‘i. In 1993, the Pauley family again, in an act of far-reaching vision and generosity, provided funds to purchase the private portion of Coconut Island and construct a new world-class marine laboratory on the island.
Before 1930
Originally, Moku O Lo‘e was used as a base for shepherds and local fishermen. During this time the island was owned by the Bishop Estate. Christian Holmes, owner of Hawaiian Tuna Packers (now Coral Tuna) and heir to the Fleischmann yeast fortune, then purchased the island for his tuna-packing factory.
The island, as it was originally purchased, was 12 acres in size and had several coconut trees, which is how it got its popular name. Holmes, unhappy with the small size of Coconut Island, had it expanded to 28 acres. Much of the material for this project came from the main sandbar in Kane‘ohe Bay (near Kapapa Island). In addition to enlarging the island, he also created many fish ponds, which would later be of great use to the Hawai‘i Institute of Marine Biology.
Holmes had a desire to transform Coconut Island into his own private paradise. He imported hundreds of exotic plants and trees to the island, and constructed a large saltwater swimming pool equipped with a slide and a diving board.
1930s
Holmes bought a 4-masted schooner in Samoa, the Seth Parker, and had it sailed north to Hawai‘i. It leaked so much on the trip that it was declared unseaworthy. He permanently moved the Seth Parker to Coconut Island and a bar and movie theater. This boat was also used in the movie "Wake of the Red Witch", starring John Wayne.
Christian Holmes built outdoor bars at various points around the island. He had a bowling alley built, and reconstructed a shooting gallery on the island that he had bought at an amusement park in San Francisco.
That’s not all. Coconut Island even housed a small zoo for a short time. Animal residents included: donkeys, a giraffe, monkeys and a baby elephant. Upon Holmes’s death, these animals became the basis for the Honolulu Zoo (along with the Honolulu Bird Park at the Kapi‘olani Park site). The baby elephant was known as “Empress” at the zoo and died of old age in 1986. Zookeepers believe her to be the longest living captive elephant.
1940s
1944: Christian Holmes passes away in New York.
1944–1947: The KMCA’s used the island as an R&R post for its officers. They built the barracks that eventually became the Hawai‘i Marine Lab.
1947: A group of five wealthy oil men bought the island. Eventually one of these men, Edwin Pauley, bought out the interests of the other four and became the sole owner of the island. Here his family spent their summers. (Note: Edwin Pauley also donated the Pauley Pavilion to UCLA. It was home to the gymnastics portion of the 1984 Olympic games.) Many famous people spent time on Coconut Island as a guest of Edwin Pauley. Some of these include: Harry Truman, Lyndon B. Johnson, Red Skelton, Richard Nixon, and Ronald Reagan.
1950–1980
1951: Edwin Pauley helped establish the Hawai‘i Marine Lab on Coconut Island and leased the necessary land to the State “rent free.”
1961: The original main laboratory building burned down. Mr. Pauley donated $300,000 towards the reconstruction of the present building, which was completed in 1965.
1965: The name of the Hawai‘i Marine Lab was changed to the Hawai‘i Institute of Marine Biology. Around this time, a tax assessor for the State noted that the land taxes being paid on the island were only for a deed covering 12 acres, yet survey maps showed the island to be 28 acres in area. This fact was pointed out to the Attorney General, who took the Pauley estate to court. Based on the argument that 16 extra acres of the island had been built using materials from sub-tidal State land, the State managed to confiscate the non-deeded land.
1980s
1981: Following the death of Edwin Pauley, Coconut Island was put up for sale. After 17 months with no action, a proposal was made for the State to purchase the land.
1987: A representative for the Pauley family came to negotiate sale to the State. Legislators assured HIMB Director Phil Helfreich they would provide support and funding. However, while they were thinking about it a Japanese real estate developer, Katsuhiro Kawaguchi, made a surprise offer of $8.5 million in cash and purchased the island.
1990s
1992: Mr. Kawaguchi and HIMB enjoyed a good working relationship for seven years. He gave HIMB a $50,000 grant. Dr. Steven Pauley (son of Edwin Pauley) visited the island where he spent his summers as a child. Meanwhile, plans for a new marine laboratory at HIMB were discussed. The Pauley Foundation and Trustees approved a grant of $7.615 million to build a marine laboratory to be named the Pauley-Pagen Laboratory.
1995: The Pauley family provided the UH Foundation with the $2 million necessary to buy the private portion of the island from Mr. Kawaguchi.
2000 and Beyond

The new marine laboratory focuses on two aspects of tropical marine biology: biodiversity and biotechnology. With the completion of the Pauley-Pagen laboratory, the future looks bright for HIMB and Coconut Island. This new addition gives the University of Hawai‘i a world-class facility for marine biology.
