Himantura fava
A stingray with honeycomb-like reticulations, likely a species complex.
The honeycomb whipray (Himantura fava) is a stingray belonging to the family Dasyatidae. It inhabits coastal waters and estuaries across the Indo-Pacific, specifically around India, Indonesia, and the Gulf of Thailand. Current understanding suggests this species may actually represent a group of closely related species rather than a single one.
Taxonomically, the species has a complicated history. The first specimens—two adult females measuring 130 cm (4.3 ft) across—were collected near Orissa, India, by the steamer Golden Crown. Scottish zoologist Nelson Annandale described them in a 1909 issue of Memoirs of the Indian Museum, noting their close relation to Himantura uarnak, with the main difference being the mouth. Smaller distinctions included a yellow (rather than white) reticulated pattern on the back and the absence of stellate denticles. Many sources still treat H. fava as a synonym of Himantura undulata.
Like other Himantura rays, this species lacks a skin fold on the underside of the tail. Its body disc is somewhat quadrangular, and the whip-like tail has variable banding. The pattern on the upper disc changes with age: adults display widely spaced, honeycomb-like reticulations, while juveniles have relatively large spots.
In Indonesia, the honeycomb whipray is targeted by commercial fisheries. Its skin is highly valued for use as galuchat, while the meat is eaten and the cartilage is also sold commercially.

Lore & Background
The first known specimens of this species were two 130 cm (4.3 ft) wide adult females collected near Orissa, India by the steamer Golden Crown, and described by Scottish zoologist Nelson Annandale in a 1909 issue of Memoirs of the Indian Museum. He remarked that it was closely allied to Himantura uarnak with the main distinguishing feature being the mouth. Smaller differences included a yellow, as opposed to white, reticulated pattern on the dorsal surface, and the lack of stellate denticles. The species has had a confused taxonomic history; many sources still consider H. fava to be a synonym of Himantura undulata.
This species is characterized by absence of skin fold on the ventral surface of the tail, in common with other Himantura species. The main body disc is somewhat quadrangular. The whip-like tail is variably banded. The pattern on the upper surface of the disc is related to age; adults have widely spaced, honeycomb-like reticulations, whereas juveniles display relatively large spots.
It is the target of commercial fisheries in Indonesia, primarily for its skin which is of high value for use as galuchat. The meat is consumed, and the cartilage also finds a commercial use.
Reader's Guide
The honeycomb whipray is notable for its commercial significance in Indonesia, where it is targeted for its high-value skin used as galuchat, as well as for its meat and cartilage. Its taxonomic status remains uncertain, as it is probably a species complex and many sources consider it a synonym of Himantura undulata. The species was first described from two large females collected off Orissa, India, and its distinguishing features include a yellow reticulated pattern and lack of stellate denticles compared to the closely allied Himantura uarnak. The pattern on its disc changes with age, with adults showing honeycomb-like reticulations and juveniles having large spots. Its presence in coastal and estuarine habitats across the Indo-Pacific underscores its ecological role, though its confused taxonomy complicates conservation and management efforts.

Frequently Asked Questions
What is Himantura fava?
Himantura fava is a stingray in the family Dasyatidae, widely known as the honeycomb whipray. It is easily recognized by the net-like, honeycomb reticulation pattern covering its disc.
Where does Himantura fava live?
This ray is found in coastal and estuarine waters throughout the Indo-Pacific. Its documented range stretches from the coasts of India and Indonesia to the Gulf of Thailand.
Who first described Himantura fava and how?
Scottish zoologist Nelson Annandale gave the species its formal name in 1909, working from two adult female specimens roughly 130 cm in disc width. Those original specimens had been collected near Orissa, India, aboard the steamer Golden Crown.
Is Himantura fava truly a single species?
Modern research indicates the name likely covers a complex of several closely related but distinct rays rather than one uniform taxon. In other words, the honeycomb whipray may be a species group masquerading as a single entry.
What family does Himantura fava belong to?
It is classified within Dasyatidae, the family that includes whiprays and their close stingray relatives. Its placement in the genus Himantura groups it with other whipray lineages in that family.
