ABOVE: This gorgeous creature is a Spotted Harlequin Snake, Homoroselaps lacteus. Not considered dangerous…gmph.
see my explanation on herping lingo for definitions. My friend Nick Schaller and I had enjoyed some good fossicking around Langebaan, with Western Dwarf Chameleons, Sand Rain Frogs and even a way-out-of-range Arum Lily Reed Frog. Nick also happened to mention that he found some harlequin snakes in the West Coast National Park. As a partly fossorial species, Harlequin Snakes are often easier to find after rains, and I headed out that afternoon to go and find one for myself. This was easier done than said, and within seconds I found a stunningly colourful individual under a rock just outside Langebaan town. I was ecstatic! I had never seen one before, and this is arguably the most attractive of all South Africa’s snakes. The species exhibits incredible variation in terms of their colours and markings, with many combinations of yellow black and red, each more beautiful than the last. West Coast harlequins are typically yellow, with broad black crossbars along the entire length of the body, accentuated by a red spine.inally, some rain on the West Coast. For someone interested in reptiles and amphibians, this means there is some good herping to be had! If you’re wondering what “herping” means –
Harlequin Snakes are described as only mildly venomous, and I have never heard of any serious bites or effects from this species. So it didn’t really cross my mind that I might soon be making a contribution to our knowledge of the venom of this species, when I reached out to pick it up. It was about 25 cm in length (probably a sub-adult; 30-40 is typical for an adult; max length 65 cm). True to form, the snake was very docile while I got some pictures of it. It made some rapid, jerky movements and tried to slither away speedily, but it did pose well for a minute or two. I then picked it up to release it back under its rock, and noticed a very slight stinging sensation on my hand. Looking down, I discovered this little guy chewing away at the soft flesh between my left thumb and forefinger. It seemed to be having some trouble latching on, given its small head and narrow gape, and it briefly released me and then went in for another sort of slow-motion strike. I did not want to yank the snake off, in fear of hurting it, so I just let it chew away. I figured that the venom would not affect me to any great extent, and that at least the snake would get some closure. It released, and I released it, and it returned to its rupicolous refuge. But this is where the story gets a little more interesting.
My sincere apologies for all these gory photos, but hey, it’s science. In summary, these were the symptoms.
- The bite itself was relatively painless; just a slight stinging sensation, and not surprising given the tiny fangs of the snake. Much less noticeable than an injection needle, for example.
- Following immediately (for the next 10 minutes or so), was a feeling reminiscent of a bee-sting, but perhaps less intense. The area around the bite became a little warmer and redder, and started swelling.
- Approximately 6-10 hours after the bite, the swelling was still restricted to my hand, but was fairly intense. The initial pain had subsided, but a stiffness associated with the swelling was noticeable. A small amount of subcutaneous haemorrhaging (bruising) was apparent on my palm.
- For the next 3 days, the swelling on my hand increased slowly, but it never really spread further up my arm. My hand was comically pudgy and stiff however. After that, it stabilized and gradually subsided.
- Starting about 2 days after the bite, and worsening rapidly, was a feeling of tenderness in my tendons and joints, particularly of my elbow and fingers. Pain was particularly intense when rotating my arm counter clock-wise. I had very little power in my arm, and struggled to lift anything sizeable. The pain in my finger joints meant that I was glad it was my left hand that was affected, otherwise writing, brushing teeth and further herping would have been difficult. After about 4 days, the pain in my hand was only apparent when I made a fist and squeezed it closed hard – definitely ebbing.
- For at least a week, there was quite severe haemorrhaging along my entire arm, concentrated in some areas to form blue-black markings. There was no significant pain associated with this though. This bruising is now hardly noticeable, about 2 weeks after the bite.
My friend James Harvey is a fellow harlequin-bite-survivor. His reported symptoms are almost identical to mine, although it sounds like he had less severe bruising, and perhaps more painful axillary glands. Headaches and general fatigue have been reported, but I cannot say that I experienced this. I did learn from this experience: it’s always a good idea to pick up snakes with your non-dominant hand. Just in case.
