Fascinating Facts Friday – Octopuses!
If you love learning about the amazing creatures, we share this world with, you’re going to enjoy today’s quick dive. This one comes straight from my aquarist friend who has taught me so many incredible things about these intelligent and fascinating creatures, the octopuses! Let’s dive in: • The plural of octopus is octopuses. Octopi isn’t actually correct because it mixes Greek and Latin. Octopod works too, especially if you don’t know the gender, it's kind of like using they/them. • Speaking of gender, you can tell an octopus' gender around 2–3 months old by looking at their third arm from the right. Females have sucker cups all the way to the tip, and males have a smooth, spoon-shaped end called the hectocotylus. • The male's arm has a very special purpose. He uses it to reach inside his mantle, grab a spermatophore (a sperm packet), and then gently place it inside the female’s mantle during reproduction. Sadly, this marks the beginning of the end of their already-short lives (usually 2–3 years). The female passes shortly after her eggs hatch, and the male passes a few months later. • The siphon, that little tube near their head, is their jet propulsion. The octopus inhales and expels water through their siphon helping them zoom around with speed and grace. • Octopuses are incredibly intelligent. They’re known as the most intelligent invertebrate, with both short- and long-term memory. They can problem-solve, open jars, and even use tools. Honestly, they’d probably be very handy in the kitchen. And if you haven’t already seen My Octopus Teacher, it is a must-see. It will make you fall in love with this beautiful, three-hearted animal. Yes, they have three hearts, which makes me love them even more! What about you? What is your favorite animal? Let’s keep learning about this wonderful animal world together. 💗
