Scoring methodology
Promachoteuthis sloani is a rare and poorly understood species of deep-sea squid belonging to the family Promachoteuthidae. It is known from a very limited number of specimens collected from the mesopelagic and bathypelagic zones of the South Atlantic Ocean. Due to the scarcity of observed individua...
Why this score
Extremely rare monotypic-family squid with high taxonomic intrigue; poor data limits broader assessment.
Scoring methodology
Abatus shackletoni is a species of irregular sea urchin in the family Schizasteridae, named for the Anglo-Irish Antarctic explorer Ernest Shackleton. Like other members of its family, it is a brooding heart urchin: females retain embryos in depressions among the spines rather than releasing larvae i...
Why this score
Shackleton association and specialized Antarctic brooding create strong historical and reproductive-interest signals despite very limited public familiarity.
Scoring methodology
The Gould's squid, also known as the arrow squid, is a species found in the waters of southern Australia and New Zealand. It is a significant target for commercial fisheries, which catch it using trawling and jigging methods. This squid is migratory, moving in response to ocean conditions.
