Small sharks often fall prey to bigger sharks and usually survive by getting more pups. But the Hardnose shark (Carcharhinus macloti) has a low reproduction rate: only one or two pups are born after a twelve-month gestation period every two years, just like in apex predators.

The Hardnose shark is a small species of requiem sharks living in shallow coastal waters of the Indo-West Pacific from Kenya through southern Asia to southern Japan and northern Australia. It is grey or bronze above and white below and was named hardnose because of the heavily calcified cartilages in its snout, unlike in other species of the genus Carcharhinus.
Female Hardnose sharks are oviviparous: one or two embryos hatch inside the uterus and are fed by yolk and later through a placental connection. Born alive at a relatively large size (18 in -45 cm-), they mature at 28 to 30 in -70 to 75 cm- and reach a maximum of only 3.6 ft -110 cm. Their skin is covered by overlapping, oval-shaped dermal denticles.
Hardnose sharks form large, sex-segregated groups and are homebodies (tagging data has shown that 30% of re-caught individuals having moved less than 30 mi -50 km- from their initial tagging location). Due to a high fishing pressure by artisanal and commercial fisheries and their low reproduction rate they are considered as Near Threatened worldwide (although in Australian waters as Least Concern).
