Crab walks around with Jellyfish on its back to protect it from predators
These #jellyfish Cassiopea (upside-down jellyfish) partake in a symbiotic relationship with photosynthetic dinoflagellates and therefore, must lay upside-down in areas with sufficient light penetration to fuel their energy source. Where found, there may be numerous individuals with varying shades of white, blue, green and brown.
Sometimes this jellyfish is picked up by the #crab Dorippe frascone and carried on its back. The crab uses the jellyfish to defend itself against possible predators.
When a squid learns to write, that’s calamarigraphy!
But seariously folks! The word “Calamari'' derives from the Greek “kalamos” for “pen” and the Latin “calamarium” for “pen case”—referencing the translucent, tapered internal shell and ink sac you’ll find in species like our local california market squid Doryteuthis (formerly Loligo)!
This pen+ink sac combo can be used for writing, if only during an invertebrate zoology lab session—though if a squid used it to sign a check, it’d be proof that they have the quills to pay the bills!
Gourmet dining at my infusion appointment today. Grape juice and graham crackers. . . . . Bit by bit, I'm figuring out how to eat lunch and dinner to get enough protein in my system. I still need soda to wash the food down, but it works. . . . . #food #medicine #infusion #treatment (at St. Jude Medical Center) https://www.instagram.com/p/CfYNyQcrii3/?igshid=NGJjMDIxMWI=
