Researchers document a rare bigfin squid during a deep-sea sighting more than 10,000 feet (about 3,000 meters) underwater off the California coast, according to NDTV. The squid is described as moving through the water with two large fins and multiple appendages, including eight trailing arms and two tentacles.

The report places the observation at extreme depth, highlighting the difficulty of studying deep-sea species. While the provided source text emphasizes the squid’s distinctive physical features used to identify the animal, it does not add details about how the sighting was made (such as the type of vessel or camera), the exact location, or whether scientists capture footage beyond the initial observation. Across the two NDTV entries, the account and description of the squid are consistent, with only minor differences in wording around the depth phrasing.
