observations were made s<strong>in</strong>ce 1990. All these whales were recorded thousands kilometers<br />
away from their usual feed<strong>in</strong>g and breed<strong>in</strong>g grounds, when they reached the Mediterranean<br />
Sea repeatedly dur<strong>in</strong>g the last years. This seems to be a new, grow<strong>in</strong>g trend, rather than an<br />
old phenomenon that went unnoticed dur<strong>in</strong>g the past (Frantzis et al. 2004). It is not known if<br />
the humpback whales that enter the Mediterranean are able to f<strong>in</strong>d their way back to the<br />
Atlantic Ocean, or if they stay <strong>in</strong> the Mediterranean Sea and die sooner or later. Frantzis et<br />
al. (2004) proposed as plausible explanations for the <strong>in</strong>creased number <strong>of</strong> humpback whales<br />
<strong>in</strong> the Mediterranean the climate change and a spillover from an expand<strong>in</strong>g North Atlantic<br />
population comb<strong>in</strong>ed with the merely explorative nature <strong>of</strong> humpback whales. In all cases<br />
the high rate <strong>of</strong> entanglement <strong>in</strong> fish<strong>in</strong>g gear poses a serious threat for all <strong>in</strong>dividuals <strong>of</strong> this<br />
species that enter the Mediterranean Sea.<br />
