The Featured Creature: Sea Sapphire: the Most Beautiful Animal You’ve Never Heard Of
This is the Sea Sapphire, an absolutely STUNNING marine copepod. Japanese fishermen would call a gathering of these creatures “tama-mizu”, or jeweled water.
Make sure to watch the VIDEO in the article!!
I swear I saw these guys in the dawn when I was taking data for my thesis last year. They float near the water surface, blinking out of sight in a steady rhythm, precisely like the gif in this post. But then again, pics or it didn’t happen, so probably it didn’t happen
this estrange-looking sea critter is Tethys vagina (Tethys by the sea goddess, wife of Oceanus and vagina.. you know very well) is a Salpa, any free-swimming, oceanic tunicate , having a transparent, more or less fusiform body.
Coccolithophores are single celled eukaryotic phytoplankton that synthesize intricate exoskeletons from crystals of calcium carbonate. The functions of these coccoliths are unknown, and may include buoyancy, osmotic regulation, protection from UV light, predation, or mechanical shock. When nutrient and light conditions are optimal, coccolithophores can form massive plankton blooms that are visible from space. Large numbers of these organisms can accumulate on the ocean floor forming chalk deposits such as the White Cliffs of Dover.
What looks like one long, swirling organism, is actually a collection of tunicates—elongated, baglike urochordates that filter water to get food—called a salp (Pegea confoederata). The chains are formed by asexual reproduction via budding done by young individuals.

Planktonic paralarvae of this genus spend an extended period in the pelagic before setting.
Limacina helicina 3 by Alexander Semenov.
Limacina helicina is a species of pteropod mollusk. ‘Pteropod’ is basically a catch-all term for all kinds of free-swimming, pelagic sea snails, usually ones with modified, wing-like foot. The sea angel Clione limacina has also been referred as a ‘pteropod’. However, its usage as taxonomic term has now become obsolete.
Dinoflagellates are single-celled organisms that live in lakes, rivers, and oceans. Some species that live in the ocean flash on contact.
This dinoflagellate model (11,000 times life size!) can be seen in Creatures of Light.

Amazing. Are those dendritic patches chromatophores?
