Tiger Catshark: Halaelurus natalensis

Family: Pentanchidae
Common name(s)

Tiger Catshark.


Slender body. Head broad. Snout dorsally compressed with upturned tip. Eyes/brows raised slightly above head. Mouth width greater than snout length. Labial furrows short. First dorsal origin over pelvic fin insertion. Second dorsal fin origin anterior to anal fin insertion. Pectoral fins broad. Anal fin fairly long. Lower caudal lobe weakly defined. Dorsal coloration uniformly cream/tan with ten dark saddles but no spots. Saddles have white/pale borders and reddish brown centres. Second saddle (behind eyes) is not joined at the top.


Maximum length at least 50cm. Size at birth unknown.


A temperate water species inhabiting rocky and sandy substrates on the continental shelf. From shallow bays to at least 114m. Usually shallow. Stays close to the seafloor.


The tiger catshark is confined to southeast coast of Africa. Found from False Bay eastwards to Southern Mozambique.

Conservation Status


The Tiger Catshark (Halaelurus natalensis) is a discarded bycatch of demersal trawl, longline, beach seine, gillnet, and squid fisheries, and is not known to be utilized or traded. Trend analysis of research trawl data in South African commercially fished areas estimated a population reduction of 67% over three generation lengths (45 years), with the highest probability of 50–79% reduction over three generation lengths. This reduction is driven partly by a steep decline in catches during the early 1990s when fishing pressure in South Africa was substantially higher. Climate change likely contributed to a range shift away from the research trawl grounds that may account for some of the estimated population reduction but that also likely represents a significant loss of habitat for the Tiger Catshark. Overall, due to an estimated population reduction over most of its range and a substantial reduction in fishing effort in South Africa, combined with a suspected range shift due to climate change that could account for some of the estimated reduction but also likely represents a decline in area of occupancy, it is suspected that the Tiger Catshark has undergone a population reduction of 30–49% over the past three generation lengths (45 years), and it is assessed as VULNERABLE.

Oviparous. 6-11 egg cases per oviduct. Egg case size approximately 4cm x 1.5cm.


The tiger catshark feeds on small bony fishes, crustaceans, polychaete worms, cephalopods and small elasmobranchs.


Poorly known. Rarely seen in kelp forests in False Bay, unlike other catshark species. Probably prefers open ground.

Reaction to divers

Rarely encountered by divers. Probably shy in un-baited situations. Fairly easy to approach on baited dives.

Diving logistics

Tiger Catsharks are occasionally seen by local divers in False Bay and at a few dive sites further east in southern South Africa. Very rarely seen on baited catshark dives in the kelp forest.

Baiting on open ground in False Bay is a good way to see this species but even then, sightings are hit and miss.

PLEASE NOTE: There are inherent risks in using bait to attract sharks on open ground (outside of the kelp forest) in white shark territory.

Similar species

Lined Catshark Distinguished by a greater amount of thinner saddles and small dark spots.

Puffadder Shyshark Distinguished by a more rounded bulbous head and more intricate markings with many light and dark spots.
