Phylum Round 3
Annelida: Segmented Worms. This group includes earthworms, leeches, and many classes under the umbrella of “polychaete”. This diverse phylum encompasses deposit feeders (eating dirt), detritivores, scavengers, deadly ambush predators, filter feeders, parasites, herbivores, and more. They are broadly defined by their repeating body segments and parapodia, which are nubby appendages used for both movement and breathing. Some have curved jaws for catching prey or scraping detritus off of rocks, while others have wide, elaborate, brightly colored feather-like fans for filter feeding. While able to crawl freely, a majority of marine Annelids spend most of their time in self-built tubes or burrows. Among their many important functions, they play a key role in mixing soil/sediment, breaking down decaying organic matter, and providing a key food source to countless other animals.
Cnidaria: Jellyfish, anemones, corals, box jellies, and hydroids. They have a gelatinous body with radial symmetry, a decentralized nervous system, and tentacles surrounding a simple mouth. The defining feature of this phylum are their cnidocytes, or stinging cells. There are two different body plans of the Cnidaria; an immobile “polyp” attached to a surface, or a free-living “medusa” which can swim or drift in the water column. Many polyp Cnidarians, such as corals, live in colonies. Some corals build reefs which serve as habitat for other animals. Free-living medusa Cnidarians must return to the seafloor in a polyp-like stage as a part of their life cycle.

Annelida is one of my 2023 holdbacks. I love that her terminal scale on her tail is one of her Palmetto spots!

The rain brings friends 🪱🌧️
I moved as many off the pavement as I could:)
Watch your step! If you can’t move them, at least don’t smoosh them!
Moving them to a grass or dirt patch is a nice thing to do:)
When worms are on pavement they can dry out or get smooshed ☹️
They come out and move around when it’s wet because it’s easier for them to stay moisturized 🪱
Safe travels, worms! 🌧️

As a social species, the way humans interact with each other are vast. However, they can rarely hold a candle to some of the bizarre ways creature of the deep ocean interact with their mates.
This is the zombie worm (Osedax) also known as the boneworm or snot worm. This odd creature sustains itself by making use of an often untapped source of nutrients - bones! This polychaete worm secretes an acid from their skin to break down the fat within fallen whale skeletons in order to feed symbiotic bacteria within their bodies.
What makes this animal even more interesting is the extreme form of polygamy they engage in. For years after their discovery human scientists were perplexed by the fact that all collected zombie worm specimens were female, eventually it was discovered that the microscopic males were living within the tissues of the 2-7cm females. Females often housed multiple mates, up to 111 'tenants' have been recorded within one female!

Cycliophora: An incredibly specialized phylum, the Cycliophorans consist of a single genus. These animals live exclusively on the mouthparts of lobsters. Yes, all Cycliophorans. This is considered a commensal relationship, as the lobster is not harmed by the Cycliophorans' presence. This phylum has an interesting reproductive strategy involving cloned dwarf versions of the male, embryos that drain all nutrients from the mother, and larvae that must be strong swimmers to hopefully re-colonize the host lobster's new exoskeleton whenever it molts.

OK this isn't a bug or even an arthropod for that matter, and I'm sure it's been brought up in the biology circles of Tumblr before BUT I wanna take a second to talk about the Giant Gippsland Earthworm (Megascolides australis)...
So, I'm sure all of y'all know the typical earthworm, just a few inches long, the type of little guy you find under a rock or in the dirt after a rainstorm, right?
Well, then you have these guys:
[Image ID: Invertebrate ecologist Beverley Van Praagh holding a Giant Gippsland Earthworm with arms outstretched to show its length / Credit and Source: Rodney Start and Museums Victoria]
These gigantic worms are about 1 metre (3 feet, 3 inches) long, are 2 centimeters (0.79 inches) in diameter on average, and can get up to 3 metres (9 feet, 10 inches) long, yet are still only 200 grams (0.44 pounds) on average! Even their babies are 20 centimeters (7.9 inches) long when they hatch!!
Speaking of the babies, they take a shockingly long time (for an earthworm) to mature! They can reportedly take up to 5 years to reach maturity.
These guys, are, perhaps unsurprisingly, native to Australia (in a relatively small section of Gippsland in Victoria), and only live underground, about 52 centimeters (20 inches) down, in moist clay, near water, and arent really spotted often because of this- However despite the fact they're typically very slow, if they move fast enough in their burrows they can be detected. Why, you may ask? Because it makes a sound, one that sounds like gurgling or sucking apparently.
This species of worm is really fascinating (as are earthworms in general)! and I also feel it's necessary to bring up the fact it's also considered to be endangered
Here's some more reading on this species for those who are interested:

Unidentified life form.
Upon first seeing these 2021, I believed they were a species of flatworm. I was told on iNaturalist that there weren't any flatworms which matched description, and that the specimens had slight signs of segmentation (thus Annelida). As it currently stands, I have seen these creatures numerous times, but have yet to find any sort of identification.
Brief description: These are benthic creatures, residing in burrows I've mainly witnessed further up the shore in mangrove environments. They remain in their burrows until there is a few centimetres of water level, after which they leave (or a part of them leaves) the burrow to feed on sediment. They sift through the sediment, possibly collecting sediment on the top-facing surface of the body/appendage to take back into the burrow. I typically find these things covered in sediment, and they leave very distinct trails in the sand after feeding. I have only come across them in Bowen (the beach at the giant mango), though I find it doubtful that Bowen is their only location.

Ursactis
Ursactis — рід червів з типу Кільчасті черви (Annelida) відомий з кембрійських сланцевих відкладів Берджесс. Типовий вид — Ursactis comosa. Більшість зразків походять з Токумм-Крік, нового сланцевого родовища Берджесс у північній частині Національного парку Кутеней, Британська Колумбія, Канада.

“Would you still love me if I was a worm?” Yet if not worms, than what, pray tell, are we? A tube within a tube is a worm’s form; No other trait defining can there be. Though humble be the worms of layman’s thought Great richness lies in their diversity. Such wonders in this world that God hath wrought Exemplified in blood and soil and sea.
Their feathers sparkle, iridescent strands – Nowhere can be found such great beauty. To touch them is to take fire in one’s hands – The pain of burning, second, third degree. Such strength and power in their mighty jaws! To sever foes in twain with gruesome glee. To feast upon their victims is their cause. No tiger matches their ferocity.
A dragon filled with flaming, wondrous life; Writhing, dancing, ‘til their fates decree. Then, in passion sharper than a knife Burst asunder in their ecstasy. A worm is but a creature, long and thin; With pow’r of life, and motion’s faculty. But see, by all that nature hides within, Why worms so oft are named “Aphrodite”.
They dwell within, in heart and flesh and blood Key players in our grand ecology. And even those which wriggle through the mud No watch compares to their complexity. A worm is more than just a mucous sheen. It’s beauty, passion, pow’r exemplary. A tube within a tube you’ve always been. And all these things and more you are to me.
...
So yeah I wrote a poem about worms
#worms#earthworm#bobbit worm#marine life#marine invertebrates#parasite#epitoky#bearded fireworm#polychaete#annelida#annelid#invertebrates#So you guys know that meme “would you still love me if I was a worm?”#Yeah I saw that and this happened#I love worms#In case you couldn't tell
