Super Sacoglossans on a marvelous macrophyte?! Don’t mind if I do! #phycyeah #marinelife🦑🧪
#tidepooling In October I finally saw my first Hedgpeth's sapsuckers (Elysia hedgpethi). These are not nudibranchs or seahares, but are sacoglossans! They are easily found on the algae Codium (aka dead mans fingers), which they eat. 🦑🦀

Nothing screams diving in Big Sur/Monterey quite like dragging yourself through thick Ptery beds 😂
Ive also heard that you can get approximate ages for individuals by counting rings in their stipes, like rings on a tree!

Chaetomorpha spiralis is our seaweed of the week! It doesn’t have a common name as far as I know, but “sea spiral” seemed fitting #PhycologyFriday

Here in California we're lucky to have not one, but TWO species of canopy forming kelps! #Giantkelp (Macrocystis pyrifera) and #bullkelp (Nereocystis leutkeana).
Who's your favorite canopy-former?

I may be biased, but elk kelp is *my* favorite canopy former
The elusive elk #kelp (Pelgophycus porra) doesn't typically grow to the surface, instead these deep-dwelling giants can form extensive subsurface canopies from 20m down to 90m! How cool is that!? #PhycologyFriday #marinelife #phycyeah
