The Sipuncula or Sipunculida (common names sipunculid worms or peanut worms) is a group containing 144–320 species (estimates vary) of bilaterally symmetrical, unsegmented marine worms. Sipuncula signifies "little tube or siphon." Traditionally considered a phylum, they might be a subgroup of phylum Annelida based on recent molecular work.
The first species of this phylum was described in 1827 by the French zoologist Henri Marie Ducrotay de Blainville who named it Sipunculus vulgaris. A related species was later described as Golfingia macintoshii by E. Ray Lankester. The specimen was provided by a friend of his, Professor Mackintosh. The specimen was dissected by Lankester between rounds of golf at Saint Andrews golf club in Scotland from which the species derives its name. Golfingia is now the genus name and Sipuncula the name of the phylum to which these worms belong.
Sipunculids are all marine. They are relatively common in shallow waters, either in burrows or in discarded shells as hermit crabs do. Some bore into solid rocks to make a shelter for themselves. Although typically less than 10 cm long, some sipunculans may reach several times that length

Sipuncula Gusano Cacahuate
The invertebrate zoology class at UNL orders a kelp holdfast shipment from Monterey Bay Abalone company in California each fall. This sipunculan was one of many marine invertebrates found in the kelp by students.

It gets its name because when the creature feels threatened, it shrinks into a peanut shape. _______________________________________________...
A sea worm's sickening tendrils have people questioning what it is, after video emerged of it squirting a membrane which moved over a man's hand. The creepy crawly, which resembles the sipuncula or peanut worm, gave its unsuspecting captors a fright when they spotted it off the coast of Thailand recently.A man holding the worm in his palm shrieks as its body contorts unnaturally before ejecting an elaborate system of sticky white roots. Using its unique digestive tract which starts in the mouth, the peanut worm can shoot out anywhere between 18 and 24 tentacles, ensnaring predators and prey alike.
I'm glad you found the time to ring.
I just spent all day waiting.
I need to know what's happening.
Well at least we both agree.
Really don't know where to start.
Did you say you met some neighbor.
I guess I'm headed for a broken heart.
Why are you doing this to me?
It's so clear.
I can hear, and i'm not gonna share you with no one.
Surprise, I've got eyes, now goodbye.
How long have you had this planned?
Guess it shows how much you care.
Now I understand how I just played the fool.
Sure I'm gonna let you go.
I was wrong to ever trust you.
Don't think that you'll ever know how you could be so cruel.
It's so clear.
I can hear, and i'm not gonna share you with no one.
