The female Reefcrawler

This specimen is already extinct. It´s because of the low chance of insemination during the mating. In the case of the reefcrawel, it´s a rather unusual way of reproducing;

The female species  are attracted to the male if he seems fertile enough. It’s recognizable to the large hump on his back, this is were he produces and collects his sperm cells. If the female finds her ideal mating partner, a short and cruel ritual begins. She starts to chase the male specimen until she has him lock in place by standing on the end of his legs. To enhance the chance of success, she starts to stimulate herself by rubbing the lips on her back-end on the male’s spermhump. We don’t know how long this ritual took but when the time was right, the female punctured the tissue of the male’s hump in order to release the sperm. Whilst moving sideways with her back-end, the female tried to inseminate herself. The part of the male in this ritual is now over, as he’s only considered a container of seed, once it’s been opened he’s useless. After the punctuation, the male dies slowly.

The belly of the female is shown here. This is how it looked when carrying an egg.

The reason the Reefcrawler got extinct is not only because of the fact that the male specimen was far outnumbered by female ones. It’s the location the reproduction took place that played a larger part of the extinction. The Reefcrawler lived around coral-reefs in the Pacific. The reprocudtion probably failed so often because of the strong currents. Sperm could therefore never reach the lips of the female and the male could only be used once.

the Trunkrat

I just realized that my very first sculpture wasn´t on here. The Jangalian Trunkrat. It´s a creature which I already wanted to make three years ago, but it was only last year when I could create time to do so. So this is the creature that started it all:

Your addition to my database of inspirations

As one of my great sources of inspiration I use prints of creatures like this one of Ernst Haeckel. Along with a great number of books and other documentation I have 40.000 digital images of animals and creatures.
As part of this great database of natural curiosities, I’m asking you as a visitor of my website, to enrich it by adding digital pictures of special creatures.

Current project


Last year I’ve been busy with a research on collecting. That in combination with my fascination for the forms of nature had led to the project I’m currently working on. I’ve started a series of collections of my own created forms of nature.

The picture above is an example of a collection of sculptures from my graduation exhibition.
