Atolla is one of the most common residents of the ocean’s midnight zone. This deep-sea crown jelly is found worldwide and can be abundant in deep water. Its bell has a signature scarlet color and bears one tentacle much longer than the rest. When MBARI researchers spotted a jelly that looked like Atolla, but lacked the telltale trailing tentacle, their curiosity was piqued.
MBARI researchers have published the scientific description of a large new species of Atolla. They’ve named their discovery Atolla reynoldsi in honor of Jeff Reynolds, the first volunteer @montereybayaquarium, MBARI’s education and conservation partner.
