[5] They likely do not travel very far for their spawning aggregations. [11], The humphead wrasse is considered an umbrella species, which means many other species are sympatric with it and have much smaller ranges—thus the conservation of the humphead wrasse's habitat would benefit these other species as well. 30.

Of those, humphead wrasse are more vulnerable to exploitation meaning a region housing healthy population numbers is likely providing exceptional habitat for the whole community.’ Kevin believes if these environments are protected for humphead wrasse, other species will benefit indirectly. (3) The young ones are found in shallow sandy regions whereas the adults are found in the deeper coral reef areas. It is found in the tropical waters of about 50 countries- from the coast of East Africa and Red Sea to Indian Ocean and Pacific Ocean. Because half of echinoids and most pelecypods hide under the sand, wrasses may rely on fish excavators like stingrays, or they themselves may excavate by ejecting water to displace sand and nosing around for prey. Crude oil normally penetrates the fur of the otter destroying the air layer that is trapped next to its skin. Humphead Wrasse (Cheilinus undulatus) The humphead wrasse is a large species of wrasse mainly found on coral reefs in the Indo-Pacific region. [12], Since so little was known about the wrasse's genetic relationships at a geographical scale, researchers utilized a test using microsatellite loci to facilitate population genetic studies.
