These are cuttlefish.
Though it may seem misleading, the cuttlefish isn’t a fish at all - it’s a type of mollusk.
You may notice that they look kind of squishy, like octopus or squid. That’s very observant of you. Cuttlefish actually belong to the same class as both the octopus and the squid (the nautilus, too - I’ll do a spotlight on them on another day; they’re pretty neat), and that class is Cephalopoda.
Much like those in their class, the cuttlefish produce a type of ink called sepia, which they use for defense and to propel them through the waters along the coasts of western Asia, Africa, Australia, the Mediterranean and East/Southern Europe.
What I think is really cool about the cuttlefish is that this ink is being used in cancer research. Scientists have actually found that the sepia extract can protect against Hodgkin’s and non-Hodgkin’s lymphoma. Furthermore, it’s been seen that the sepia restores marrow on the subjects tested, which would be beneficial during chemotherapy. Not only that, but it’s also been found to kill tumors!
