According to the study, the "sea monster," which scientists dubbed Daihua sanqiong, shares a number of anatomical characteristics with the modern comb jelly
The researchers mapped the full genetic code of the Pacific sea gooseberry, the nickname for a comb jelly
species known as Pleurobrachia bachei.
There are about 80 kinds of comb jelly
in the world, and about 20 of them are found in Japan, according to Horita.
One dramatic example is the Atlantic comb jelly
, a U.S.
In a large auditorium at the Monterey Bay Aquarium, 200 people watch a huge video image of a twinkling comb jelly
. "What is that thing?" a girl in the audience calls out.
Salt water invades coastal wetlands or aquifers, and salt residue creeps into irrigated land; storm surges invade coastal cities; alien species such as the Leidy's comb jelly
or brown tree snake invade foreign ecosystems; dangerous human pathogens, such as drug-resistant tuberculosis or ebola infect human bloodstreams; pollutants flow across boundaries on wind or water currents; and garbage is trucked or barged from affluent places to poor ones.
The team had sequenced the genome of the comb jelly
species Mnemiopsis leidyi and compared it with genomes of sponges and dozens of other organisms.
This is the pathogen: the Leidy's comb jelly
(Mnemiopsis leidyi), a widespread species but nothing special.
Steve Haddock remembers every detail about his first ocean encounter with a comb jelly
. The open water was a bottomless deep blue.
Although this species of comb jelly
can grow nearly 10 centimeters long in Arctic waters, the researchers collected animals that were no more than 1.6 millimeters long--equivalent to the diameter of a strand of spaghetti.
