"Discovery of Jet Black Deep Ocean Eggs"
Researchers in Japan have discovered jet black egg capsules belonging to flatworms at a depth of 20,000 feet in the Kuril-Kumchatka Trench, marking the first clear evidence of these creatures living at such extreme depths. The eggs, found attached to rock fragments, contained embryos at varying stages of development and were virtually indistinguishable from their surface-dwelling counterparts. This suggests that flatworms from shallow waters may have gradually colonized deep ocean environments over time.
