  • What are the key similarities and differences between a squid and an octopus?

    Q: What are the key similarities and differences between a squid and an octopus?

    A: Squids and octopuses are both head-footed cephalopods, but their behavior, habitat and physical characteristics are different. Both are blue-blooded aquatic animals, as their blood contains copper and has oxygen-carrying molecules, and they both move by jet propulsion and live in salty waters in temperate zones. They both squirt ink, but it's different colors. Squids produce blue-black ink while octopuses squirt black ink.

  • How do squid breathe?

    Q: How do squid breathe?

    A: Squid breathe by drawing water through their siphons into their mantles, the large muscular coverings over their bodies, where it passes over their two sets of gill filaments, absorbing oxygen and releasing carbon dioxide via diffusion. The blood that absorbs the oxygen uses a copper compound, haemocyanin, rather than the iron-containing hemoglobin of mammals. The blood is pumped to the gills from two branchial hearts and elsewhere by a third.
