In Hawai‘i, blacktip reef sharks will reach an average of 5.5 feet in length. “Nearshore, shallow water nurseries provide food and abundant shelter where baby blacktip reef sharks can avoid bigger predators, such as other sharks,” Mr Bouyoucos said. The two dominant shark species there are grey reef and blacktip reef sharks. The effects of habitat on the ecology, movements, and foraging strategies of marine apex predators are largely unknown.

Just like all other known sharks, blacktips have evolved specialized cells in their snouts called electroreceptors. However, the importance of these habitats in sustaining marine species at seascape scales is debated, and their significance to reef shark populations is poorly understood.

Blacktip reef sharks are often the most abundant reef sharks in their area [28] and they may have the important role in controlling the trophic level. The blacktip reef shark Carcharhinus melanopterus is a widely distributed mobile marine predator; we explored its use of shallow, turbid coastal habitats in the Great Barrier Reef using tagging and acoustic telemetry.

The blacktip reef shark prefers shallow, inshore areas where it is less vulnerable to larger species of sharks in the open ocean. The lead author of the study is Ian Bouyoucos, a PhD student at the ARC Centre of Excellence for Coral Reef Studies at James Cook University (Coral CoE at JCU). “Nearshore, shallow water nurseries provide food and abundant shelter where baby blacktip reef sharks can avoid bigger predators, such as other sharks,” Mr. Bouyoucos said. Black tip reef sharks feed on smaller fish that populate the coral reef, like small rays, crabs and lobsters. Juvenile blacktip reef sharks as a study species were chosen because this shark is known to use nearshore areas as nurseries for their young, said study author Ornella Weideli from the Save Our Seas Foundation D'Arros Research Centre and Ph.D. student at the Centre de Recherches Insulaires et Observatoire de l'Environnement (CRIOBE) in France.
