An enormous male sperm giant carcase that looks like the world ’s biggest marshmallow has been haunting the beach of Oahu , Hawaii , for the past calendar month . Now , scientist are taking advantage of the stagnant sperm whale ’s close propinquity to the shore and using it as an chance to learn more about these large maritime mammals .
The blow , bloated white carcase first showed up on Jan. 10 near Oahu ’s south shoring . double , authorities tow the carcass out to sea in an seek to keep it aside from the beach . " The thinking is that they [ whale carcasses ] often havesharks feed on them , and if they get close to a beach , they could get close to shoring where the great unwashed are swimming , " said Kristi West , director of the maritime mammal stranding programme at the Hawai’i Institute of Marine Biology .
Authorities tried to tow the floating whale carcass away from beaches, but it returned — twice.
But after both tows , just days later , the carcass return to shore . After the 2nd attempt fail , federal agency decided to go forth the carcase where it landed , on a outback beach on Oahu ’s west side that ’s not shop at by bather . [ Whale Album : Giants of the Deep ]
During itsfloating journeying around Oahu , the whale carcass was in a middling advanced state of decomposition , appearing like a somewhat falsify , gusty marshmallow . That ’s because the whale ’s outer stratum of gray - colourize skin very apace moult off after it exit , revealing the top of the heavyweight ’s fatheaded , white blubber layer , West said .
" When they ’re [ hulk ] alive and well , you would n’t see the clean , " she said . Inside the carcass , gases were released that caused the abdominal dental caries to enlarge outward . " That explains the balloon look . "

Bloated , white whale carcase are n’t researcher ' favorite form of marine mammals to examine because it means the animate being has been utter for quite a while . Not only are they really smelly and kind of gross , but " we ca n’t do all the examination we could do on a really unused [ bushed ] hulk that strands , " West say .
Nonetheless , West and her fellow worker are doing their honorable to study what they can about the animal and why it died . " We ’ve been monitor it every day , " she said .
The whale is positioned mighty along the shoreline , so during a recent low tide , scientist work quickly to necropsy the abdomen of the whale . They were most concerned in thewhale ’s belly contents , West said . The research worker find no grounds ofplastic or marine debris ingestion , which hasbeen live to cause trauma to spermatozoan whalesand other whale mintage around the earthly concern . Instead , the whale ’s stomach was empty , " so that tells us the fauna had n’t scrounge , " West state .
Researchers took advantage of a recent low tide to necropsy the sperm whale’s abdomen. They found an empty stomach, which suggests the whale wasn’t in good health when it died. Photo taken under NOAA permit #932-1905.
West and her fellow worker suspect that the empty tummy mean the animate being was probably sick when it died . Sperm whalesdive K of feet to run their preferred prey : deep - weewee calamary and octopus . These nautical giants exhaust about 2,000 lb . ( 900 kilograms ) of nutrient each day , according to theAmerican Cetacean Society , and it remove a lot of vitality to take in that much fair game . If this sperm whale was n’t in skillful wellness , it would n’t have had the energy to Holman Hunt , West suppose .
The necropsy also allowed the researchers to take measure and judge that the giant was about 55 foot ( 16.7 metre ) long , which is around the maximum size of it for a virile sperm whale , West say . As the carcass continues to break up , West and her team will try out the heavyweight ’s bone fabric to define if the puppet wasstruck by a ship . But so far , not enough bone has been exposed to definitively say there was a ship smasher .
When people come across a dead marine mammal , they should be sure to let government know immediately so that research worker can analyze the animal as before long as potential , West say . " As the decomposition goes on and on , there ’s less detailed information that we can gain from these animals that live far out at ocean , " she suppose . " We really reckon on the public to report them . "
