Bottlenose, Common and Rissos are the dolphins most likely to put in an appearance, the number of dolphin sightings has varied from 3 or 4 to 20+ in a season. Pod numbers vary from 1 or 2 to scores on occasion - Commons most likely in large groups.
Minke Whales, whilst the most common species of whale sighted in these waters, vary greatly in terms of time of season and frequency from one year to the next. Food distribution has been increasingly varied in recent years. Weather conditions on the day will affect probability of sightings as will the experience and alertness of observers! May to August are "probably" the more likely months.
Unusually, in 2007, a Hump Back Whale put in a brief appearance to the West of Mull, before realising its mistake and heading back to the ocean!
2007 was a good year for Killer Whales - Turus Mara boats had above average (6) sightings of pods with 2 - 5 creatures in each.
