An octopus kiss

And here's an octopus being indecent

+ They have blue blood

Vertebrates' blood is red because it contains hemoglobin (protein + iron). Invertebrates' blood contains hemocyanin (protein + copper) which makes it colorless when deoxygenated and blue when oxygenated.

Horseshoe crabs also have blue blood

Their blood is very important for vaccine production because it's used in a test called LAL to detect the presence of endotoxins in vaccines and medical equipment.

Horseshoe blood contains amebocytes (like our white blood cells). Once these amebocytes detect endotoxins, they encapsulate them and form a gel clot around them. That's basically how the LAL test works; if you add horseshoe blood to your vaccine and it forms gel, then it's contaminated.
