Hasselt's Bambooshark

Here's a shark caught from local waters by Angelfishing. From the fin count and orientation, it is certainly a bamboo shark. I would appreciate it if anyone can help identifying or providing reference to this shark.

From what I know...it is called 'sian nang swa' in Hokkien, which translate to 'lizard shark'. But the mentioned shark is supposedly have spots on them.

Edit: Identified as
Hasselt's Bambooshark (Chiloscyllium Hasseltii)

2 possibilities: Chiloscyllium indicum (slender bamboo shark) or Chiloscyllium hasseltii (Hasselt's bambooshark).
Slender Bamboo: Image

Was the fish still alive when the photo was taken?
I have no pics of hasselt's bamboo shark but I'm vouching for it. The specimen you have here does not have spots or speckles though the overall body shape and fin arrangement's the same (unlike the slender bamboo) The description for hasselt's indicates the species as brown-coloured in the adults and banded in the juveniles. What's more certain in your photo and in the written descriptions is the presence of black edgings in the adults (last remnants of juvenile colour). Your specimen looks like it has black edgings on some of its fins. I'm just making an educated guess and may be entirely off but to me it seems like the closest answer

I believe the shark is well alive when the shots were taken and was released after that. Angelfishing will be able to verify on this. If I recalled correctly, she said that this shark is pretty small in size too(can't recall the length), not sure whether it's an adult or juvenile since both sharks you mentioned don't grow very large. Yes, I noticed some of its fins have black edges too. Here's two higher resolution pictures if you want a closer look: pic 1 pic 2

Referencing on the common sharks in local waters from fishspecies, the slender bamboo shark is on the list and stated as a native fish though. But as you've said, we don't really have a picture of the Hasselt's bambooshark to compare it with.

I still have no idea which is it though. :lol:

Hi TimL,

Yes, the fish was alive when the photos were taken.

Peace/Angie,

I think it is Chiloscyllium hasseltii. Why? Because you can't find information on it. :lol:

Ok Ok don't poke me already. I tell I tell :cry: :lol: Lemme drink my coffee and slowly type.

1. Confirmation that it is Chiloscyllium family - Nostrils subterminal on snout, preoral snout long, mouth closer to eyes than snout tip.

2. Mouth well is in front of the eye. Looks like.

3. Big Big eyes. About 2% of body length

4. Between dorsal to dorsal the distance is about 10% of total length.

5. Snout to vent is about 33-35%

6. Long and Low anal fin just before the tail

7. First dorsal-fin height 5-8% of total length.

8. Second dorsal-fin height 7.5-9% of total length.

Not much people do research on this shark, me dunno why too. Anyway this mysterious Chiloscyllium hasseltii is non other than Indonesian bamboo shark. :lol: Males maturing between 44 and 54cm, and adult males 54 to at least 59 cm. This fella should be a maturing-matured fella, still can see one black mole on its right side just above the prepctrorial fin.

If i remember clearly Chiloscyllium indicum dun have the long low anal fin. :cocktail: :lol:

Thanks for the new insights on this shark Tere. I find it quite difficult using that description to identify the shark though. However, we'll put it as Chiloscyllium Hasseltii for the time being until someone can show otherwise. :nod: Thank you all for the contribution. :) :flower:
