The journal “Sri Lankan Wildlife” also aims at mobilizing all communities and get their utmost support and attention for the conservation of Sri Lanka’s land and sea wildlife resources, and especially the critically endangered species of Sri Lanka. This issue of “Sri Lankan Wildlife” is focused on marine wildlife in Sri Lankan waters which has vivid diverse biodiversity compared to land biodiversity. We always value and appreciate reader's comments. We hope to release the next issue of “Sri Lankan Wildlife” in a new format. “Sri Lankan Wildlife” is now available onboard Sri Lankan aircraft as an e-journal starting with the previous issue (Volume 08). This was made possible by the Sri Lankan Airline Limited and we are thankful to them.
