Incredible Close up Video of a Spider Shows How its Heart Beats through its Translucent Skin

The amazing moment of the arachnologist captures the spider's heart beating with its flexible skin

This unusual video was shared on the Facebook group Australian Spider Identification on Sunday and shows the fascinating biology of spiders.

'When you look at the top of the abdomen, the heart and the marker make it look like an anchor' writes the spider expert.

The man says he got a rare opportunity to record his heartbeat and just found a 'right spider at the right time', with a flexible body to make the heart appear.

The spider's body was light enough to beat its heart, as some Facebook users were amazed at its biology

The spider's heart lies beneath the surface of the abdomen and runs down the center of its body.
