Cute kelp! I was pleasantly surprised these were common picks for freebies. I was kinda expecting that folks wouldn't be into it, but they were. Yey! I do think, I'd change the color on the bull kelp. I took artistic license with them being green as it is. Kelp is really more of a yellow color anyway. Brown algae after all. But I still think they come out nice~

Heterokonta, el reino naranja
Los heterocontos o estramenopilos (Stramenopiles) son uno de los grupos con mayor diversidad de especies. Podemos encontrar tanto organismos unicelulares como pluricelulares abarcando varios nichos. Una característica de la mayoría de las especies de este grupo en al menos alguna de las etapas de sus ciclos vitales es la presencia de dos flagelos diferenciados, uno con mastigonemas (proyecciones similares a cerdas de cepillos) y otro liso y menos desarrollado.
Dentro de los Heterocontos podemos encontrar organismos autótrofos unicelulares como son las diatomeas (Bacillariophyceae), las cuales pueden encontrarse flotando sobre la columna de agua (planctónicos) o en el lecho de los cuerpos de agua (bentónicos) y pluricelulares como feofíceas (Phaeophyceae) llamadas comúnmente algas pardas. Algunas de ellas, tales como Laminaria sp. se encuentran sujetas al sustrato, un caso similar pasa con Macrocystis sp., con la única diferencia de que esta cuenta con neumatocistos en la base de sus láminas, estas estructuras le ayudan con la flotabilidad, manteniéndola erguida. Ambas especies conforman los denominados bosque de kelp. Por otra parte, algunas especies de feofíceas como el sargazo (Sargassum sp) se encuentran flotando libremente gracias a los neumatocistos con los que cuenta.
Una característica muy llamativa que presentan los heterocontos autótrofos es la presencia de clorofila a y c,la cual se cree que es producto de la fagocitación y endosimbiosis de los cloroplastos de las algas rojas en algún momento de su historia evolutiva.
Por otro lado, podemos encontrar organismos heterótrofos como los Opalinos (Opalinata) donde encontramos a Protoopalina, los cuales son comensales dentro de los intestinos de algunos organismos como anfibios o reptiles y también organismos saprofitos y parásitos como son los Oomicetos (Oomycetes), organismos morfológica y ecológicamente similares a los hongos pero que no guardan ninguna relación con ellos, como es el caso de Peronospora sp.
La reproducción en estas especies puede ser tanto asexual como sexual y en el caso de las feociceas se presenta la alternancia de generaciones, es decir, que las formas haploides y diploides son pluricelulares y de vida libre.

Algae Extract for Skin: Benefits, Easy DIY and How it Works
Tumblr media
Welcome to the world of skincare innovation!

Join us as we explore the natural treasures of the sea and unlock the potential for healthier, radiant skin.
In the ever-evolving world of skincare, where beauty enthusiasts are increasingly turning to nature for holistic solutions, one ingredient has garnered significant attention: algae extract.
Algae, often associated with aquatic ecosystems, might not be the first thing that comes to mind when thinking about skincare, but its potential benefits for the skin are making waves in the beauty industry.
As the demand for natural and sustainable skincare options continues to rise, algae extract has emerged as a promising ingredient due to its unique properties and diverse applications.
As you are about to dive into the world of algae extract for skincare, explore what it is, its numerous benefits, how it works on the skin, and how you can incorporate it into your daily routine.
Whether you’re a skincare aficionado or simply curious about the latest trends in beauty, read on to discover the secrets of harnessing the power of algae for healthier, more radiant skin.
What is Algae Extract?
Algae extract is a natural skincare ingredient derived from various types of algae, which are simple, photosynthetic aquatic organisms.
While algae might conjure images of slimy seaweed on the ocean floor, these versatile organisms have been harnessed for their beneficial properties in the world of skincare.
There are three primary types of algae used in skincare:
Green Algae: These include popular varieties like Chlorella and Spirulina. Green algae are rich in chlorophyll and essential fatty acids, making them excellent for nourishing and revitalizing the skin.
Brown Algae: Fucus vesiculosus (commonly known as bladderwrack) and laminaria are examples of brown algae used in skincare. They are prized for their hydrating and antioxidant properties.
Red Algae: Carrageenan and agar-agar are derived from red algae. They are known for their ability to soothe and protect the skin, making them valuable in sensitive skin formulations.

Took an old toothbrush to my deer mandible, but the algae doesn't want to come off. I suppose it's kind of fun to have a bone that turns bright green whenever it gets wet.
