Bigfin Squid vs Giant Squid: common questions

Which one has famously huge eyes?

The giant squid is the one with famously huge eyes, up to 27 centimetres across and the largest known in the animal kingdom, a feature not documented as unusual in the bigfin squid.

Which one holds its arms bent at a right angle?

The bigfin squid is the one with this unusual posture, holding its ten extraordinarily long arms bent sharply at a right angle, a habit not shared by the giant squid's more typical feeding-tentacle strike.

Which one was first filmed alive more recently?

The giant squid was first filmed alive in 2012, while the bigfin squid remains rarer still, known almost entirely from occasional footage captured by deep-sea submersibles and remotely operated vehicles.
