Strawberry squid (Histioteuthis heteropsis)
Photo by Paul Caiger @ Woods Hole Oceanographic Institution
One of my favorite creatures ever!! 🦑・゚✧*:・゚✧
These beautiful elegant creatures are found in the tropical/subtropical waters of the Atlantic and Pacific oceans. They live in the Mesopelagic zone which is often also referred to as the “twilight zone.”
Strawberry squid can be found between depths of from 1,000 meters (3300 feet) and the surface, where they go at night to feed
The photophores within the tissues of their skin produce a distinctive bioluminescent flashing glow which attracts prey. That’s why they look bedazzled!
Strawberry squids have asymmetrical eyes that allow them to perceive light in both bright and dark surroundings. One eye is small and blue while the other is large and yellow and both were adapted for their own unique purpose!
I could go on forever bc these creatures are not only so breathtaking but also soooo incredibly interesting

Nautilus are a large swimming marine molluscs restricted to a handful of species in the family Nautilidae from around the Coral Triangle, a roughly triangular area in the tropical waters located between the Pacific and Indian oceans. They are conformes by two different groups, fuzzy nautilus (Allonautilus) and common nautilus (Nautilus) with nearly eleven species, as researchers have recently added three new nautilus species.
A previous work showed a difference in genomic along different populations, now a international team of researchers combined previous work with image analysis software,using pigmentantion, shape and total shell area of they data set, confirming the presence of three unnamed species, here as Nautilus samoaensis, Nautilus vanuatuensis and Nautilus vitiensis.
According to researchers, nautilid shells implode at depths greater than 800 m and depth therefore acts as a biogeographical barrier separating these species.
-Where all Nautilus species distributed in the Coral Sea and the South Pacific.
According to researchers, all nautiluses are regulated under appendix II of the Convention on International Trade in Endangered Species (CITES). At the moment, no species of Nautilus or Allonautilus has been formally assessed by the International Union for Conservation of Nature Red List. All they face illegal trade. This study may provides a foundation for managers and other officials to begin to efficiently identify distinct species of nautilus shells that may come through as trade products.
