Common Dolphin


Common Dolphins filmed in waters between the islands of Coll and Mull (Inner Hebrides) last month. Common dolphins are thought to be one of the most abundant cetacean species, with population estimates suggesting that there are several hundred thousand animals globally, yet overall numbers have declined due to a combination of factors. There is evidence that significant numbers of common dolphins are accidentally caught in open sea trawl and drift nets; they seem particularly vulnerable to this threat because they are attracted by the fish inside the nets but do not jump over them to escape. Common dolphins are also subject to the same threats as other cetacean species including the pollution and degradation of the marine environment, injury and disturbance from vessels, and decreasing food resources due to overfishing.
