An ever growing species list of the cool critters that we see on muck dives means there’s always something new to learn and even something new to discover as well.

Keeping current with changes in classification or new information is an ongoing effort and something we like to pass onto guests who come and dive with us. Whether it’s new Nudibranch species or changes to the Frogfish family, we like to be up to date with whatever might affect us here in Lembeh.

In general, Frogfish aren’t the hardest to ID once you’ve familiarised yourself with the more common species and the differences between them. However there are a few that are still hard to differentiate.

The Ocellated/Lembeh (Nudiantennarius subteres) Frogfish, the Freckled (Abantennarius coccineus) Frogfish and the Spotfin (Abantennarius nummifer) Frogfish are probably the three most common species that divers struggle with in Lembeh as they share many of the same characteristics such as colour, size, habitat and skin patterns/texture.

This little Frogfish has been one of our latest discussions about which species it is. We can rule out the Freckled Frogfish straight away as that Frogfish lacks a distinct tail base unlike this little guy here. So then we are left with the Spotfin or Ocellated Frogfish.

Both species share a spot on the rear dorsal fin and both can be seen in this shade of orange. With the Spotfin the lure tends to be more round whilst the Ocellated has a more elongated, downwards facing lure.
The membranes between the fins are much more deeply incised on Ocellated Frogfish and the Spotfin Frogfish have a more orangey-brown spot on their side above their “legs” which may or not be visible if they have accumulated some sediment.

I know which species we are leaning towards…….how about you?

Why Dive With NAD-Lembeh Resort?


NAD-Lembeh Resort is a small, owner-operated, photography-oriented dive resort in the Lembeh Strait. We are situated in a private bay on Lembeh Island, away from the hustle and bustle of the mainland. We guarantee a 2:1 guest to guide ratio as standard, which makes for a private dive experience and lots of time to take pictures.


All our rooms (10 Beachfront Rooms, 5 Seaview Bungalows) offer ocean view, air conditioning, hot water, wifi, including full board. Our resort has only few steps, which makes our layout extremely convenient to get from your room to the restaurant, camera room, bar and floating jetty.


Our dive team consists of 15 full-time guides, with over 100 years of combined experience! Air as well as Nitrox and various cylinder sizes (both DIN and Yoke are available onsite).


NAD-Lembeh has 4 large, purpose-built dive boats. Each at around 15m long, they offer lots of space and comfort for the divers. Boats feature onboard toilets, towels, drinks and snacks and first aid/ oxygen.

Our jetty allows our guests dignified and quick boat entries – all our dive boats can be moored simultaneously, so there is no wading through the shallows to get on the boat for the dive!


Our focus at NAD is to take your underwater photography to the next level. We offer 1:1 photo classes and our guides are all proficient with photography, using our rental equipment for fun dives when not diving with guests.

We shoot video up to 8K, along with Nikon/ Canon SLR and mirrorless setups. This gives us a rounded knowledge of all cameras. We are also the go-to location for natural history filming in the Straits.


Our newly renovated, huge camera room offers one work space for each and every guest. The spacious, individual benches with lots of power points were purposely built for underwater photographers. NAD’s dedicated camera room is also the perfect place to work on and edit your pictures.

Several rental cameras and strobes are available onsite. We have basic tools and spare parts in our gift shop in case of minor camera problems as well as a drying cabinet, and computer for you to work on and edit your photos.
