What a worm!
ReplyDeleteIt looks like a pile worm (Neries Vexillosa). Pile worms are common members of the phylum annelid (segmented worm). They live in the mid to low intertidal from central California through Alaska all the way to the shores of eastern Russia. These guys are common in the intertidal mud under coble and among mussel beds or in burrows. They can be identified by their biramous parapodial lobes! What in the world is that? They also have an impressive set of retractable jaws for catching prey, but they generally like feasting on algae. Do you think this might be an important prey species? Who might like to eat this strange looking worm? Not me!
Thank you for telling us what it is. Would a bird, like an oystercatcher, eat this worm? Would a bear eat this worm? We need to look this up to learn more.
