In the eastern North Pacific (ENP), the taxonomic status of the long-beaked (<i>bairdii</i>) form has been controversial since its original description in 1873, and has vacillated between species, subspecies, and geographic forms several times. It is currently provisionally viewed as a subspecies of <i>Delphinus delphis</i>, <i>D. d. bairdii</i>. To clarify this situation, we reviewed the literature and conducted additional analyses using both newly obtained genetic and cranial morphometric data sets. The results indicate that there are diagnostic differences in skull morphology and coloration between the eastern Pacific long-and short-beaked forms, and near-perfect diagnosability in mitochondrial DNA. These differences, along with indications of ecological distinctions, including important differences in life history parameters and reproductive timing, indicate that these forms are well on their way down separate evolutionary pathways. As such, we consider them to be distinct species in the eastern Pacific.

Their geographic range extends from the western North Atlantic across to the eastern North Atlantic, and includes the Norwegian and North Seas, but their distribution patterns are not well-understood (Cipriano, &lt;span&gt;2018&lt;/span&gt;; Vollmer et al., &lt;span&gt;2019&lt;/span&gt;). There is a relatively high occurrence of mass strandings by this species, and it is also impacted by anthropogenic threats such as bycatch in a variety of gear types, including trawls and gill nets (Addink et al., &lt;span&gt;1997&lt;/span&gt;; Bogomolni et al., &lt;span&gt;2010&lt;/span&gt;; Couperus, &lt;span&gt;1997&lt;/span&gt;; Kinze et al., &lt;span&gt;1997&lt;/span&gt;; Palka et al., &lt;span&gt;1997&lt;/span&gt;). Additionally, Atlantic white-sided dolphins are hunted, primarily in the Faroe Islands, where, for example, 1,428 individuals were killed in a single drive hunt in 2021 (https://nammco.no/topics/atlantic-white-sided-dolphin/; Calderan, &lt;span&gt;2021&lt;/span&gt;; Fielding, &lt;span&gt;2021&lt;/span&gt;). They are thus one of the most heavily exploited cetacean species in the North Atlantic, yet also one of the most poorly-understood. Passive acoustic monitoring (PAM) has the potential to contribute to knowledge on their occurrence, but there is only limited information on white-sided dolphin vocalizations (Cones et al., &lt;span&gt;2023&lt;/span&gt;; Hamran, &lt;span&gt;2014&lt;/span&gt;). It is therefore not currently possible to analyze the many data sets collected from acoustic moorings and towed array surveys to improve knowledge of the species' temporal and spatial distribution.&lt;/p&gt;&lt;p&gt;Most dolphin species produce tonal and pulsed vocalizations, including whistles, echolocation clicks, and burst pulses. Echolocation clicks are typically associated with foraging and navigation, and whistles and burst pulses with social communication (Au, &lt;span&gt;1993&lt;/span&gt;; Herzing, &lt;span&gt;1996&lt;/span&gt;). Whistles are frequency-modulated tonal sounds (Herman &amp; Tavolga, &lt;span&gt;1980&lt;/span&gt;). Echolocation clicks are short-duration, directional clicks (Au, &lt;span&gt;1993&lt;/span&gt;); burst pulses also comprise clicks, where broadband pulsed signals with significant ultrasonic frequency components are produced with a very high repetition rate and short interclick interval (Au &amp; Hastings, &lt;span&gt;2008&lt;/span&gt;; Blomquist &amp; Amundin, &lt;span&gt;2004&lt;/span&gt;). Clicks associated with burst pulses are reported to be shorter in duration, more directional, and have lower peak and center frequencies than those associated with echolocation click trains (Au &amp; Hastings, &lt;span&gt;2008&lt;/span&gt;; Rankin et al., &lt;span&gt;2007&lt;/span&gt;). All three vocalization types can include specific information useful for classifying to species level (Rankin et al., &lt;span&gt;2016&lt;/span&gt;). The limited data on the clicks produced by &lt;i&gt;Lagenorhynchus&lt;/i&gt; species indicate interspecies variability in their characteristics.

As a group, marine mammals are the largest mammals on earth. The smallest marine mammal (by mass) is the marine otter (&lt;i&gt;Lontra felina&lt;/i&gt;), weighing 3–5 kg (Jefferson et al., &lt;span&gt;2015&lt;/span&gt;), which is over 10 times as much as the smallest terrestrial mammal, the Etruscan shrew (&lt;i&gt;Suncus etruscus&lt;/i&gt;), weighing 1.8 g (Jürgens, &lt;span&gt;2002&lt;/span&gt;). Similarly, for the opposite end of the size spectrum, the blue whale (&lt;i&gt;Balaenoptera musculus&lt;/i&gt;)—the largest animal to have ever lived—is approximately 150,000 kg (Sears &amp; Calambokidis, &lt;span&gt;2002&lt;/span&gt;) compared to the 5,000 kg African elephant (&lt;i&gt;Loxodonta africana&lt;/i&gt;; Laurson &amp; Bekoff, &lt;span&gt;1978&lt;/span&gt;). The large body size attained by marine mammals represents an evolutionary trend to balance energy costs associated with thermoregulation and foraging (Gearty et al., &lt;span&gt;2018&lt;/span&gt;; Goldbogen, &lt;span&gt;2018&lt;/span&gt;; Williams, &lt;span&gt;1999&lt;/span&gt;) and selects for larger neonates (Christiansen et al., &lt;span&gt;2014&lt;/span&gt;, &lt;span&gt;2018&lt;/span&gt;). The lower limit of body size in marine mammals is thought to be constrained by the thermal demand of seawater, which conducts heat 25 times faster than air at the same temperature.&lt;/p&gt;&lt;p&gt;Body size largely determines surface area to volume (SA:V) ratios. Smaller animals have a larger surface area for a given volume, resulting in thermoregulatory consequences. Surface area (SA) represents the area over which heat can be lost to the environment. Volume (V) represents internal heat generation as metabolism scales with mass, which scales isometrically with volume. Large body size is advantageous for conserving heat since larger animals have lower SA:V ratios due to the scaling relationships between length, SA (length&lt;sup&gt;2&lt;/sup&gt;), and V (length&lt;sup&gt;3&lt;/sup&gt;) (reviewed by Ashton et al., &lt;span&gt;2000&lt;/span&gt;). This scaling relationship yields a more rapid increase in V than in SA with body length (cubed vs. squared), resulting in greater heat generation and retention relative to heat dissipation. In marine mammals, species inhabiting colder climates minimize their SA:V ratio by changing body shape and/or increasing body size, which reduces heat loss compared to those in warmer climates (Adamczak et al., &lt;span&gt;2020&lt;/span&gt;; Worthy &amp; Edwards, &lt;span&gt;1990&lt;/span&gt;).&lt;/p&gt;&lt;p&gt;This trend has been described for both terrestrial (James, &lt;span&gt;1970&lt;/span&gt;) and marine mammals (Ashton et al., &lt;span&gt;2000&lt;/span&gt;; Torres-Romero et al., &lt;span&gt;2016&lt;/span&gt;) under Bergmann's rule. Bergmann's rule was first proposed in 1847 (Bergmann, &lt;span&gt;1847&lt;/span&gt;) to explain the congeneric pattern of larger animals (specifically endotherms) in higher latitudes with colder climates. Since its conception, Bergmann's rule has also been investigated within species and across species as well as in endotherms and ectotherms, demonstrating its open criteria (Meiri, &lt;span&gt;2011&lt;/span&gt;).
