B. pectinirostris is closely related with a similar Boleophthalmus fish known as Boleophthalmus boddarti or Boddart’s goggle-eyed goby. Both have two dorsal fins that resembles a ship sail, but the latter has some zebra strips on the body. Boddart mudskippers are found in southern Vietnam, especially in Cần Giờ mangrove forests (Ho Chi Minh city), or in Cù Lao Dung island (Sóc Trăng province).
Also, B. pectinirostris is often mistaken for the giant mudskipper (Periophthalmodon schlosseri, Vietnamese: cá thòi lòi). The latter is dark brown with less visible spots, much bigger eyes and head (compared to the body), and has the ability to climb trees.
Cooking mudskippers in general is challenging because those fish have a very strong smell. The common cooking method is braising with pungent spices like lemongrass and chili, or with some special herbs that can mask or dispel the fishy and muddy smell. Known herbs are Indian camphorweed, Catunaregam tomentosa (găng), and Vietnamese coriander (Persicaria odorata, rau răm).
