Closeup of the scutellum of Fasta fastuosa

Darkfield micrograph of a thrips (Parthenothrips dracaenae). I spread the wings using a fine needle so that both pairs are visible.

Head of a beetle larva I found in a brackish/marine habitat. Brightfield microscopy. 10x objective

Photo of (almost) the entire worm in regular brightfield microscopy. The intestine is visible as a sort of meandering river of darker cells. Near the middle there is a repeating structure that I think may be eggs/egg-bundles/ovaries?

Family Chernetidae

From above (dorsal) the origin of the name becomes apparent. The scales male it look like it’s made from gelatine. Especially when you find it under a rock during low tide!

A. gelatinosa from below (ventral) showing the iridescence of the body. You can also make out the parapodia very well against the huge jelly-like scales.

Me standing on the shore of a small lake that is surrounded by cliffs

A (non-realistic) „sticker“ I drew in procreate of Eulalia sp., a green paddle worm of the family Phyllodocidae.

The head of my bx41 microscope with my camera adapted to the top of it.

A small part of the entire artwork. Crocheted corals of various kinds and other reef-life in yellows oranges and reds. It doesn’t even begin to capture the beauty of it irl

A copepod (probably Cyclops sp.) against black background. Notably, this individual has large orange oil drops in its body.

Crown of a magnolia tree (also in full bloom) against a perfectly blue sky

View from underneath cherry tree in full pink bloom.
Due to the over-exposure the sky is almost completely white.

Bluray box of the complete series of Planet Earth.

Copepod female as seen through a microscope at 100x total magnification. Lateral view. The background is turned black.

The copepod is currently carrying two pale greenish egg sacs.

Onychophore-closeup against a black background.

Closeup of A. branchialis against a black background. It is very clearly segmented. Every 5 segments is a chaetiger (bristle-carrying segment). Later (on from chaetiger 11 or 12) the worm has very pronounced branchiae that were definitely not a nightmare ar all to draw the black background around, I promise you. :)

Overgrown copepod (habitus) at 40x, dark field. Image taken through eye piece of microscope with my phone. Background edited to be completely black.

Photo stack taken with my iPhone through an eye-piece at 200x + digital crop.

Algae and peritrich(?) ciliates attached to a copepod.

Macro photo of the head Peripatoides novaezealandicae from ventral.
You can see the “teeth” very well. And if the upload quality is enough the structure of the cuticle (better than on the mCT scan).
You can even see what I have called the “thingies on the thingies”.

Screenshot of a digital 3D model. 3D reconstruction made from Micro-CT scan of an Onychophore.

Sagittal cut. I love how you can see the antennal nerve. Also the brain is very cool.

Nematode under my new microscope (Olympus BX41) at 200x magnification + digital crop

Photo of the nose piece/objective turret of my microscope with three objectives (from right to left: 4x, 10x, 20x. All Olympus UPlanFL N)

Olympus BX41 compound microscope with trinocular head, fluorescence capability (has three filter cubes), and a phase contrast condenser. Next to it the power supply for the mercury vapour lamp.

The microscope is fully functional (electronics and mechanics work perfectly) I just need to get some eye pieces and objectives.

A round, slightly oval sponge with lots of bumps against black background. It has a lot of long calcareous bristles sticking out. The opening (osculum) is pointing towards the right. On this side the Bristles are significantly shorter than on the other side. Some of the bristles end in a crown of backwards pointing spines.

Sponge skeleton against black background:
The whole thing is tube shaped, only the upper third is visible, coming into the frame from the bottom right corner. At the end, the spicules form an organic web-like structure, fanning out towards edges. On the side, the spicules are arranges horizontally and vertically, forming rectangles. There are additional fan-like formations at regular intervals.

A brightfield image of Macrothrix sp. It's shape is roughly like that of a daphniid, but it has an elephant-trunk-like snoot and long spines at the posterior margin of the carapace. It is completely transparent, only the gut is slightly yellowish

A calanoid copepod under the microscope. It has very long antennae with one antennae having thickened and orange segments in the center. Apart from that, the copepod appears colourless

Amphipod against a black background. The main colour is blue with red margins on each of the tergites. The eyes and antennae are reddish as well. The last two pairs of pereopods extend backwards and have white tips. Overall, the body is smooth and rounded.

Pisidia longicornis against a black background. A brown individual with a marbled patterning on legs and back. It has a round body with three long legs visible on either side as well as a pair of claws. The right claw is slightly enlarged. It has very long antennae and big, round, red eyes.

Green shrimp against a black background. It has a long pointy rostrum and very large scaphocerites. The telson and uropods are also pretty long. Sadly I didn’t manage to take a lateral photo as it was quite jumpy

Closeup of the head of the Daphniid at 400x magnification (brightfield microscopy). It is completely covered with the little algae.

A Daphniid with hundreds (thousands(?)) of little green single celled organisms scurrying around it and attached to it. It looks like they got underneath the carapace as well. Bright field microscopy at 100x magnification.

A copepod against black background. It’s white/transparent with orange patterning and orange egg sacs.

A Rough Grey Isopod (Porcellio scaber) sitting on a porous volcanic rock. As it's name suggests it is uniformly grey in colour and has a rough texture.

A dark brown isopod sitting on a piece of bark. It has subtle markings on its back and rather long legs and antennae. They are also really fast. I found them in the Victoria lily house in the stony flower bed right next to the pool.

A closeup of Xantho pilipes against black background. Its legs are fluffy (which has likely inspired the name "pilipes"). The back is white with a red marking in the middle that sort of looks like a space ship(??). The legs and claws are of an equal red with the tips being darker.

A greenish pill-shaped ostracod with a big thorn-shaped ala. The rest of the animal can roughly be made out through the carapace. The margin of the carapace has small perforations as well as a few hairs.

Pale brown isopod against a black background. It has a relatively sturdy build, two pairs of rather short antennae the posterior end is pointed. Its uropods (2 per side) end at about the same level as the point and are spaced quite far apart.

It also has some red algae on its butt

Photo of a zoea larva under a microscope. It has a very large compound eye and a long dorsal thorn that curves back on its carapace. The abdomen is long and thin, ending in curved spine(s) at the telson.
Above the zoea is the exoskeleton of the cirri ("feeding legs") of a barnacle.

Terebellid worm against a black background. It has a lot of white tentacle-like appendages at the front that curl into little springs and curls. A bit behind there's a pair of tree-like branchae. The first few segments are thickened with prominent (but small) parapodia(?). Behind that the animal gradually gets thinner and smoother. It starts out a fleshy pink colour with brighter reds and oranges towards the middle of the worm and transparent at the back. It currently has a bit of sediment in its guts which gives the transparent part a brown appearance.

Closeup of an amphipod against a black background. It’s pale brown/orange in colour. It has the typical amphipod shape except that its gnathopod 2 is modified into a big claw.

Closeups of 9 different flowers arranged in a 3x3 grid. In order from top left to bottom right:
1) Pilosella aurantica (Asteraceae)
A vivid orange flower (technically flower head or capitulum comprised of lots of individual flowers)

2) Dianthus deltoides (Caryophyllaceae)
A magenta flower with 5 petals that have serrated margins. Towards the center they get soeckled with white

3) Bellis perennis (Asteraceae)
Typical daisy-like capitulum with white ray florets anf yellow disc florets

4) Dianthus carthusianorum (Caryophyllaceae)
Magenta with 5 petals that are slightly more spindly than on D. deltoides. It also lacks the white spots

5) Draba verna (Brassicaceae)
A group of 3 bright white flowers and some buds. It has 4 petals which each have a deep incision

6) Lysimachia arvensis (Primulaceae)
Salmon orange blossom with 5 petals. It turns violet towards the center with 5 brightly yellow stamens

7) Dianthus sp. (Caryophyllaceae)
White blossom with pink center. The 5 petals also have serrated outer margins and leave no gaps in between each other. In the center, the markings of the petals form a circle

8) Oxalis stricta (Oxalidaceae)
A yellow blossom with 5 petals. The center is greenish. There are a lot of short stamens.

9) Geranium pratense (Geraniaceae)
A violet towards purple flower with 5 broad petals. The colour softly fades to white in the center. The stamens are a very dark purple, almost black and quite prominent.

Closeup of the chromatophores (taken from the lateral view of the image above).

Combined image of the lateral and dorsal view of A. nitescens against a black background. It’s shrimp-shaped and has two small (but prominent) claws with white tips.
Along the back center line the 6 abdominal segments each carry one white spot.
The uropods are a very deep blue, with white feathery „hair“ at the edges.

A closeup of C. erythropus against a black background looking out of its shell. It's brown with some light blue spots and has feet that are striped red and the same shade of blue. Four of them are hanging out of the shell as well as the left claw which is enlarged. It has bright red-orange antennae and the stem-like eyes are black with white spots.

Aeolidiella sp. against black background. It’s curled up a bit and has two rows of groups of 4 brownish cerata.

Bright orange springtail with a plump body. It has little bumps on each segment and some bristles. The little antennae have 3 segments and the tips are white

Medieval manuscript illumination. Half snail, half cat? Cat in a shell? Hermit crat?? Who knows. And it has antennae too.

Phyllodoce lineata against a black background.
The head (top middle-left) has a bright yellow main colour, turning more muddy towards the tip. There are 4 short antennae located at the front as well as 4 pairs of long "tentacles" (tentacular cirri), 3 of which point backwards, and 1 forwards.
In the front half, the back of the body, which is segmented as in all annelids, is also yellow with 3 brown spots per segment (one in the center, 2 on either side at the base of the parapodia). This gives the worm a stripy look.
In the back half, the worm is entirely brown. The bottom side of the worm is a light turquoise colour and slightly iridescent.
On each segment, the worm carries to leaf-shaped appendages, sometimes referred to as paddles.

It’s a fossilised snail from the side embedded in a rock matrix. The shell ranges from orange to white (but is mostly beige). The rock is also beige.

A stack of 2 snails (this time of different species) on top of another on a sandy leaf. The bottom snail (Trochulus hispidus) is flat and hairy, the top snail (Pupilloidei indet.) is taller than wide but very tiny.

Two snails of the same species (Gonyodiscus rotundatus) stacked on top of each other, the top one being significantly smaller. The houses are very flat, with many ridges.

A red and orange crab with a round body and an immense left claw. The legs have small spines on them.

The antennae are „striped“ and extend 45° backwards.

An overview of Epitonium clathrus.
Left: From the side with the aperture visible
Top: From the apex
Bottom: From the bottom
Right: From the side, with the aperture facing away
In the bottom right corner there is text with a scale bar and species name.

The shell itself is white with a tall spire and 7 whorls in total. Notably, the shell has evenly spaced ribs that go from the bottom all the way to the tip.

A light pink polychaete worm with a magenta line down the center. Some parts are a bit yellowish.

Photos of Calliostoma zizyphinum from four different sides. The shell is cone shaped, roughly as tall as wide and has a beautiful red and white pattern.

On the bottom right there is a scale bar and the scientific name (in grey).
