They look a lot a like (although pigeye sharks have no recorded human attacks). They are robust and bulky, sporting a grey color on their dorsal side and a white belly, also having a pale band on the flanks (sides). They have small eyes and a short, blunt snout… actually, with this description, doesn’t it sound exactly like the bull shark?
Differences? Quite a few: precaudal (before the caudal fin) vertebral count (89–95 in the pig eye versus 101–123 in the bull shark) and the sizes of their dorsal fins, fewer tooth rows in the lower jaw than the bull shark to name a few. Another important difference: pigeye sharks do not go into brackish/freshwater, unlike the bull shark.
However, even though these sharks look a lot alike, there isn’t concrete evidence about their evolutionary relationship.
Fun fact: An albino pigeye shark was caught off Queensland in 1987. [Albinism in the pigeye whaler shark Carcharhinus amboinensis (Muller and Henle) from Queensland. RJ McKay, K Beinssen. Memoirs of the Queensland Museum 25, 463-464, 1988.] An adult pigeye measure anywhere from 1.9m to 2.5 m (6.2–8.2 ft) long, the largest measuring up to 2.8 m (9.2 ft) long.
They practice live birth to anywhere between three to thirteen pups, after a gestation of up to a year. As in many sharks, the young stay safe in sheltered bays and lagoons, movements following tidal/seasonal patterns.
The IUCN presently lacks adequate data to assess the conservation status of this species.
