Unknown Seaweed I have no idea what this is! Maybe a weird, red Ascophyllum nodosum? Or, Nemalion helminthoides? Or, Sarcodiotheca gaudichaudii?<br />
<br />
It was bright red with some orange new growth. Also, it had red bladders on the main stems, which were reddish brown.<br />
<br />
Habitat: On a beach in the lower intertidal zone.<br />

  1. Definitely not an expert, but it looks like Sarcodiotheca gaudichaudii to me! Posted 6 years ago
    1. The color definitely fits with that species, but the bladders don't. I haven't gotten much feedback on an ID yet, except that there is some agreement that it looks like Ascophyllum nodosum. The color is totally off though. A. nodosum is snarky green-brown. This was definitely vibrant red! I have no idea what would make it red. WEIRD. Posted 6 years ago
