Brock, Director for the Division of Fish and Gar.® for Hawaii, 
toild the GHILTQH’S Science seminar Friday, 
Most under-rated hazard, and therefore one of the worst 
dangers to personnel at Bikini, will be sunburn,. Mr. Brock 
declared. "Regardless of how much shipboard tan you may acquire 
there is always danger of getting a severe burn through over 
exposure." 
Mr. Brock, who spent many months at Bikini last year with 
the Fish and v/ildlife Service, then went on to point out other 
dangers that Bikini Scientific Resurvey personnel should be 
aware of. 
Coral cuts 
Ordinarily, it’ 
ing a cut until 
, he warned, are easy to get and can be painful, 
s good policy to remain in the water after receiv 
the wound cleanses itself by bleeding. 
He also warned that painful injuries can be received from 
sea urchins. Spines from these organisms are barbed and sharp. 
They usually break off at skin level and are very difficult to 
remove. Mr. Brock described several types of stinging coral. 
Some of those, he said, cause reactions like poison oak. 
He described the sting of the Portugese Man of jar, found 
in Bikini waters, as about like a burn from a red hot wire. 
Many fish found in the lagoon and along Bikini reefs are 
capable of inflicting serious wounds. By exercising care in 
handling these fish, once they are out of the water, most 
injuries can be avoided, he said. 
One of the most dangerous is the scorpion fish. Its spines 
are hollow like hypodermic needles. Poison is injected through 
'the hollow spine when the victim’s skin is punctured. 
Eels, found in holes in the coral around the reefs, can 
inflict dangerous bites when disturbed, Mr. Brock said. He 
warned all Resurvey personnel to avoid cone shells. These 
contain an animal that is capable of inflicting a fatal sting, 
he said. 
Recording to Mr, Brock, there are three types of sharks 
found around Bikini. Most common of these is the rather timid 
black tip type that abounds in shallow water. These rarely 
exceed six feet in length. 
The second type found around Bikini is the gray shark that 
usually feeds in the dee];- water channels. Most dangerous of 
the Bikini sharks is the white tipped variety. 
In addition to the three types mentioned, a tiger shark 
was captured last year at Bikini. Its stomach, when opened, 
was found to contain a pair of dungarees, ship’s garbage, and 
fish enough to fill a good sized garbage can. (At this point 
it should be explained that the dungarees hadn’t been occupied 
when eaten. They apparently were discards thrown overboard 
from some ship in the Crossroads fleet,) 
rhile Mr. Brock believes that most sharks found around 
Bikini, under ordinary circumstances, will not attack swimmers, 
he points out that they all have the dental equipment to make 
a nasty bite.
