Tikaganizira za akangaude, nthawi zambiri timajambula maukonde a utawale omwe amagwiritsa ntchito kuti agwire nyama zawo. Tsopano, kafukufuku watsopano wofalitsidwa m'buku la Ecology and Evolution akusonyeza njira ina yodabwitsa imene kangaude amagwiritsira ntchito ulusi wake—mtundu wina wa ku Madagascar wakhala ukusokera masamba pamodzi kuti upange msampha wotchera chule.
Zodabwitsa ndizakuti, gulu la ofufuza omwe akuchita kafukufuku wazachilengedwe ku Madagascar adatulukira mwangozi. Tsiku lina m’maŵa, atamaliza kuwerenga mbalame ku Ambodiala, anaona kangaude (Sparassidae, Damastes sp.) akudya chule. Zamoyo zopanda msana zomwe zimadya zamoyo zam'mimba sizodziwika, koma ofufuzawo akukhulupirira kuti lipoti lawo ndi limodzi mwa ziwiri zokha zomwe zimafotokoza za nyamazi ku Madagascar.
Kangaude wamtundu womwewo wawonedwanso katatu, makamaka m'minda ya vanila kudera lonselo. Chochititsa chidwi kwambiri ndi chakuti akangaude onse awonedwa pafupi kapena mkati mwa malo obisalapo masamba "osokedwa" ndi ulusi. Malo ogonawo amatseguka pang'ono kumbali imodzi, kuwapangitsa kukhala ngati malo ozizira obisala achule, otenthedwa ndi dzuwa la Madagascar, omwe sadziwa kuti kangaude akubisala mkati mwake.
Kangaude woyamba anapeza akudya chule akubwerera kumalo ake obisala a masamba pamene ofufuza akuyandikira kuti ajambule chithunzi. Akangaude otsalawo ali pafupi kapena akadali m'malo obisalamo masamba ofanana. Zikuoneka kuti sizisonyeza kukonda mitundu ina ya mitengo, chifukwa masamba a mitengo yosiyanasiyana akhala akugwiritsidwa ntchito popanga malo obisalamo. Koma chimene chimawagwirizanitsa n’chakuti onse “amasokerana” ndi ulusi wa silika wa akangaude.
“Kutentha kukakwera, achule amafunafuna mthunzi ndi kubisala kutali ndi nthaka, zomwe akangaude amapereka ngati pogona,” analemba motero olembawo m’nyuzipepala yawo. “Achule amatha kusankha misampha yomwe ikuwoneka ngati yotetezedwa poyesa kubisala kwa zilombo zina, monga mbalame zomwe zimasanthula zomera kuti zipeze nyama ... Damastes sp."
Ofufuzawo akuvomereza zolephera za kafukufukuyu, chifukwa chimodzi chokha chimene anachiwona chinali chakuti kangaude amadya chule. Amazindikiranso kuti nyama zazikulu monga chule zimawonedwa mosavuta ndi diso la munthu ndipo siziyenera kutengedwa ngati umboni wosonyeza kuti ichi ndi khalidwe lofala. Komabe, machitidwe a akangaude omwe "amasoka" masamba kuti apange pogona ndi ochititsa chidwi.
