Cheeked Pipefish (Corythoichthys insularis) is a species of marine fish in the family Syngnathidae.
Cheeked Pipefish's Behavior & Ecology
Distribution Countries - Western Indian Ocean: Amirante and Comoros islands. Also reported from the Maldives.
Cheeked Pipefish habitat
Corythoichthys insularis inhabits coral and rocky reefs to depths of 45 m (Kuiter 2000, FishNet2 2016). There have been no feeding studies done on this species, but most other pipefishes tend to prey on small planktonic and/or benthic crustaceans (Kendrick and Hyndes 2005). They are ovoviviparous, and males brood the eggs under their tail prior to giving live birth (Dawson 1985).
Corythoichthys insularis is under threat from coral reef habitat loss. Corals are threatened globally due to coastal development, pollution, destructive fishing, and the effects of climate change (ocean acidification and rising sea surface temperatures - Carpenter et al. 2008, Normile 2016). Although the reefs in the area are healthier than most, similar threats are present in this region and are predicted to increase in the future (McLanahan et al. 2007a,b, 2014). In Comoros, degraded reefs are prevalent and associated with coastal development (Freed and Granek 2014). The species is however also able to inhabit rocky reefs (FishNet2 2016). Further research is needed to determine how much wild populations of this species are affected by the loss of corals.
