Bull Kelp (Nereocystis luetkeana) is a brown algae that can grow up to 118 ft tall, with a single hollow stalk topped by a carbon-monoxide-filled pneumatocyst and dozens of long blades. It is the only kelp known to drop spore patches near its holdfast, ensuring the right concentration of spores settles nearby.

"unlike #animals that carry two complete sets of chromosomes, #BrownAlgae only carry the male V or the female U chromosome, determining their sex... brown #algae gametes engage in a mesmerizing mating dance... Female gametes fix quickly onto substrates and release a pheromone in seawater to attract males. Male gametes actively swim using two flagella in progressively closer circles"

"450 million years ago, brown #algae transitioned from unicellular to simple multicellular forms. This was driven by #HorizontalGeneTransfer from #bacteria... Around 200 million years ago, following the breakup of #Pangea, brown algae underwent significant species diversification"

"Most brown #algae are yellowish-brown, but #scuba divers noticed that a species resembling #Sporochnus shimmers like peacock feathers in yellow, bright green or blue when direct light is shone on them."
