In 2005, Kiwa Hirsute observed to attack the shell-broken vent mussels and intrude into vent mussel beds. Scientists looked upon this action as symbolize of prey. They supposed that Kiwa Hirsute is ‘probably omnivorous’ based on video. The mussel, algae and some kinds of small animal near hydrothermal vents may be on the diet of Kiwa Hirsute
According to the interview of Dr. Michel Segonzac, the man discovered Kiwa Hirsute, Kiwa Hirsute was described as a “general carnivore” because he claimed that two Kiwa Hirsute was seen to fight over shrimp. It supports the argument of ’probably omnivorous’ raised by Macpherson.
Another hydrothermal was raised after the Kiwa Hirsute was observed to wave the chelipeds slowly near hydrothermal vent. The methodical movement made the scientists thought the meaning of it. The initial explain of this movement is that Kiwa Hirsute tried to keep another creature away. However, the location of that movement usually is at the seep point of methane. The scientists associated the bacteria which could be bloomed with the heat and mineral substance of hydrothermal vent with the hairy chelipeds.
After the chemical analysis of the bacteria on the chelipeds and rostrum of Kiwa Hirsute, it could basically sure that Kiwa Hirsute cultures the bacteria on the chelipeds for eat. As the chief energy source in hydrothermal vents, the bacteria had been found in almost all creatures near hydrothermal vent. However, it is the first time to discover a creature to cultures the bacteria.
As the video of Kiwa Hirsute shows that Kiwa Hirsute could drop the bacteria down by the comb-like mouthparts. Moreover, the chelipeds is a good culturing farm for the bacteria. The motion of waving the chelipeds at the methane leakage point may be a method to provides more nutrition to the bacteria. This discovery has contributed much to the study of Kiwa Hirsute.
The distinctive food supply of Kiwa Hirsute may be one of the contributing factors of the chelipeds of Kiwa Hirsute. As far as I know, there is no evidence to prove that the chelipeds of Kiwa Hirsute could be used to detect the tiny current in the deep sea. The scientist mentioned that this may help the Kiwa Hirsute to find the better nutrition recourse for the bacteria.
The mussels and shrimps could provide more energy than the bacteria, but they are not easy to catch. The bacteria may are the grain reserve when there is no adequate food, just like the monkey eats the flea. Maybe this is the reason of why the Kiwa Hirsute is regarded as an omnivotous creature.
