Taxonomy Tournament: Annelids

Bonelliida. In this order of unsegmented marine worms, the males are much smaller than the females, and typicaly live on or inside them.

Echiurida. This suborder of marine worms is known as the spoon worms, and includes the penis fish

Would you still love us if we were a worm? 🥺👉👈

What’s cuter than sharing? Sharing is caring, after all, and no other muddy buddy does that better than the fat innkeeper worm (Urechis caupo). These seafloor superheroes burrow in the soft sediment of estuaries and earn their name by providing shelter, food, and even running water for their fellow members of the muck, like pea crabs, ghost shrimp, scale worms, and arrow gobies. They’re also a source of food for many other animals including leopard sharks and sea otters!

Round 1 - Phylum Priapulida

(Sources - 1, 2, 3, 4)

Priapulida is a phylum of unsegmented marine worms commonly known as “Penis Worms,” due to their general shape and retractable proboscis.

Like kinorhynchs (which seem to be their closest relatives) they live in the mud of shallow waters worldwide. Larger species tend to live in colder seas while smaller species live in warmer waters. They range from 0.2–0.3 cm to 39 cm (15.35 in) long. Their body is divided into a main trunk/abdomen and a swollen proboscis region, called the presoma, ornamented with ridges. The presoma, with the mouth at the tip, can be retracted into the trunk and is used in locomotion as well as in feeding. Members of the family Chaetostephanidae secrete a gelatinous tube, open in both ends, which they live in. Most families are carnivores that feed on slow moving invertebrates such as annelids, but some feed on detritus while others are filter-feeders. They have separate sexes, and usually breed by releasing sperm and eggs into the water, though at least one species is known for internal fertilization.

Priapulid-like fossils are known from the Middle Cambrian, with modern groups appearing in the Carboniferous. They were likely major predators of the Cambrian seas. The mouth of priapulids seems to be an original trait inherited from the last common ancestor of both priapulids and arthropods, though arthropods no longer possess it.

Please keep in mind that I am ordering phyla from furthest related to us to closest related to us. Of all the different groups of animals covered so far that we call worms, these are the closest related to us. And I think that’s beautiful.

Some species are very tolerant of hydrogen sulfide, anoxia, and low salinity. They are ~survivors~

In an Alaskan bay as many as 85 adult individuals and 58,000 larvae of Priapulus caudatus per square meter have been recorded. That’s a lot of penis worms!

They don’t even know they look like human penises. Imagine if giant aliens came to earth and made fun of us because we looked like their genitalia.

Okay but would you love your partner if they were a penis worm?

How ace (& oblivious) am I? Well, whenever a new "do not [blank] the forbidden stalactite/crystal/rock/etc" goes around, I think, "awww, but I want to eat the pretty candy." And then I scroll down and every time it's like, wait, you guys were talking about sex?!?

i do believe polls were a great addition to tumblr as a concept but the dash is way too full of them. every third post is a poll and i've decided to reblog way less of them. i see a poll and i'm like goddamn what do you wanna know now gay boy.
