"to Thai, squid, octopus, and cuttlefish are all ปลาหมึก. For English speakers, those are similar things, but all clearly distinct. But for Thai speakers, they're all ปลาหมึก, just different types."

Then, ปลาหมึก = coleoidea? If so, the squid, octopus, and cuttlefish are (in English and many other languages) all just types of coleoidea: https://en.wikipedia.org/wiki/Coleoidea
