Research journal
What science is revealing.
New papers, unusual behaviour, evolution, and discoveries from across the invertebrate world — collected in a growing research journal.
Animals worth a closer look
Introvertebrates is about the animals that get flinched at, misread, and underestimated — explored through video, writing, and tools for people who find them genuinely fascinating.
In my care
Tarantulas and other spiders, an assassin bug, sun beetles, and Sonja, a Reeves’s turtle. The full collection now has its own room to breathe.

Read the keeper guideFrom the living Codex
Public-safe totals and standout measurements from the same field log used to follow feeding, molts, growth, and time in care. Missing measurements stay missing rather than becoming estimates.
Community field log
A moderated home for remarkable measurements, keeper photography, and individual animal stories. Every published claim shows the evidence level behind it.
Your own Codex data stays private unless you deliberately prepare and share a public-safe submission.
Follow the close-ups
The cinematic slideshow stays quick to browse. Below it, selected public posts and reels load directly from @introvertebrates_yt.

Behind Introvertebrates
I’m Erlend, the keeper, photographer, writer, and builder behind Introvertebrates. The project grew from a lifelong interest in animals and a desire to replace reflexive fear with closer observation.
Here I bring together my current collection, original photography and video, research notes, and digital tools — all built around the same idea: misunderstood animals become far more remarkable when we take the time to look.
Introvertebrates Codex
A dedicated digital companion for tracking the animals in your care. The Codex is currently in development.
