“Amnios” . . . for lunch today

A follow up, although we have probably jumped the shark by this time! Here you go! (Highlights are from the source, not me..)

The term amnios (or amnion) comes from Ancient Greek. It originally referred to a "little lamb" or a shallow bowl used for collecting sacrificial animal blood. Historically, ancient scholars borrowed the term to describe the delicate fetal membrane because these membranes were frequently studied in sheep. [1, 2, 3]
The Diminutive: The suffix -ion indicates a "little" version, leading to amníon (\(\dot{\alpha}\mu\nu\text{í}\text{o}\nu\)
The Shift to Medicine: Early anatomists noted that the fetal sac of a sheep is very thin, white, and clear. Because of this clarity and its association with a lamb, early scientists adapted the Greek word to describe the innermost fetal membrane (and the sac holding amniotic fluid) across various species, including humans. [1, 2, 3, 4, 5, 6]

Thanks Gina for the research. Still think it a strange choice, IMHO , for a name of a restaurant.
 
Sea turtles are classified as amniotes, meaning they belong to a group of vertebrates whose embryos develop within a specialized set of fluid-filled internal membranes, including the amnion. [1, 2, 3, 4]


The amnios or amnion is a crucial, fluid-filled membranous sac that directly surrounds and cushions the developing sea turtle embryo. It acts as a localized aquatic environment inside the egg, allowing the embryo to grow without drying out while protecting it from physical shocks. [3, 5, 6]
The 4 Membranes of a Sea Turtle Egg
Sea turtle eggs are considered amniotic eggs. They contain four distinct, extra-embryonic membranes, each with a specific survival function:
  • Amnion: Cushions the embryo in a stable, fluid-filled environment.
  • Yolk Sac: Stores and digests the nutrients the growing baby turtle needs to develop.
  • Allantois: Aids in respiration (gas exchange) and safely stores metabolic waste.
  • Chorion: Encloses all the other membranes and assists the allantois in facilitating oxygen and carbon dioxide exchange through the eggshell. [4, 11, 12]
Why this Evolutionary Trait Matters
Because sea turtles carry their own "aquatic environment" in the form of amniotic fluid, they do not need to lay their eggs in water. This allows the mother to lay her soft, leathery eggs in sandy nests on land, completely shielded from the harsh ocean currents and marine predators. [2, 4,
