My central questions ask:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Can we use features visible on the skin like epidermal diseases, lesion severity, scarring from orcas, boats, and fishing gear, and potentially cyamid loads as biomarkers of physiological stress or nutritional status?<\/li>\n\n\n\n<li>How do these skin-based indicators correlate with environmental variables, prey availability, fecal hormones, and overall body condition?<\/li>\n<\/ul>\n\n\n\n<p>By tracking these patterns across individuals and years, my goal is to understand how gray whales are responding to a changing ocean and whether their skin can tell us more about what&#8217;s under the surface.<\/p>\n\n\n\n<h4 class=\"wp-block-heading has-text-align-center\">What are cyamids?<\/h4>\n\n\n\n<p>Cyamids, more commonly known as \u201cwhale lice\u201d, are small crustaceans that live exclusively on marine mammals. Despite their nickname, cyamids are not true lice\u2014they\u2019re actually amphipod ectoparasites, more closely related to beach hoppers than anything you&#8217;d find in your hair. For gray whales (<em>Eschrichtius robustus<\/em>), these tiny passengers are a constant presence throughout their lives.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/osu-wams-blogs-uploads.s3.amazonaws.com\/blogs.dir\/2115\/files\/2025\/04\/cyamid.png\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"682\" src=\"https:\/\/osu-wams-blogs-uploads.s3.amazonaws.com\/blogs.dir\/2115\/files\/2025\/04\/cyamid-1024x682.png\" alt=\"\" class=\"wp-image-6032\" srcset=\"https:\/\/osu-wams-blogs-uploads.s3.amazonaws.com\/blogs.dir\/2115\/files\/2025\/04\/cyamid-1024x682.png 1024w, https:\/\/osu-wams-blogs-uploads.s3.amazonaws.com\/blogs.dir\/2115\/files\/2025\/04\/cyamid-300x200.png 300w, https:\/\/osu-wams-blogs-uploads.s3.amazonaws.com\/blogs.dir\/2115\/files\/2025\/04\/cyamid-768x512.png 768w, https:\/\/osu-wams-blogs-uploads.s3.amazonaws.com\/blogs.dir\/2115\/files\/2025\/04\/cyamid-1536x1024.png 1536w, https:\/\/osu-wams-blogs-uploads.s3.amazonaws.com\/blogs.dir\/2115\/files\/2025\/04\/cyamid-2048x1365.png 2048w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/a><figcaption class=\"wp-element-caption\">Figure 1. Gray whale blow hole area covered in barnacles and cyamids. The circle inset shows a zoomed in area where you can see the orange cyamids aggregating near the more yellow barnacles.<\/figcaption><\/figure>\n\n\n\n<p>Each whale can host thousands of cyamids at a time, with individuals often clustering in specific areas of the body that provide physical refuge from the currents: around the blowhole, in the crevices of flukes, along the rostrum, genital slits, and especially around wounds or skin irregularities (Figure 1). Unlike barnacles, which attach directly to the skin and remain stationary while they feed on nutrients in the passing water, cyamids grasp onto the whale\u2019s body using claw-like appendages, feeding on sloughed skin and bodily fluids. This relationship is generally not thought to be harmful to the whale, but high cyamid loads can be indicative of poor health, injury, or compromised immune function.<\/p>\n\n\n\n<p>There are several species of cyamids, and many are host-specific\u2014meaning they\u2019ve evolved alongside particular whale species. In gray whales, the most common is <em>Cyamus scammoni<\/em>, which specializes on gray whales and is rarely found elsewhere. Other species found on gray whales include <em>Cyamus kessleri<\/em>, and the rarer <em>Cyamus ceti<\/em>. Cyamids are transmitted primarily from mother to calf, which helps explain their host fidelity, but horizontal transmission (between unrelated individuals) may also occur during close contact which can explain some rare occurrences of cyamids that are found outside of their general host species. In fact, <em>Cyamus ceti<\/em> was only found once on gray whales in 1861 but is generally thought to be specific to bowhead whales, giving us potential insight into interspecies interactions (bowhead and gray whales can spatially overlap on Arctic foraging grounds).<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><a href=\"https:\/\/osu-wams-blogs-uploads.s3.amazonaws.com\/blogs.dir\/2115\/files\/2025\/04\/image-3.png\"><img loading=\"lazy\" decoding=\"async\" width=\"770\" height=\"768\" src=\"https:\/\/osu-wams-blogs-uploads.s3.amazonaws.com\/blogs.dir\/2115\/files\/2025\/04\/image-3.png\" alt=\"\" class=\"wp-image-6033\" srcset=\"https:\/\/osu-wams-blogs-uploads.s3.amazonaws.com\/blogs.dir\/2115\/files\/2025\/04\/image-3.png 770w, https:\/\/osu-wams-blogs-uploads.s3.amazonaws.com\/blogs.dir\/2115\/files\/2025\/04\/image-3-300x300.png 300w, https:\/\/osu-wams-blogs-uploads.s3.amazonaws.com\/blogs.dir\/2115\/files\/2025\/04\/image-3-150x150.png 150w, https:\/\/osu-wams-blogs-uploads.s3.amazonaws.com\/blogs.dir\/2115\/files\/2025\/04\/image-3-768x766.png 768w\" sizes=\"auto, (max-width: 770px) 100vw, 770px\" \/><\/a><figcaption class=\"wp-element-caption\">Figure 2. <em>Cyamus scammoni <\/em>close up photographs of (A) aggregation, (B) juvenile stage, (C) dorsal side of an adult, and (D) ventral side of an adult showcasing the cyamids corkscrew shaped gills (Takeda et al. 2005)<\/figcaption><\/figure>\n\n\n\n<p>Because cyamids are permanent residents of the whale\u2019s skin, they offer a unique window into both individual whale life histories and broader ecological trends. Their location, abundance, and distribution can potentially inform us about wound healing, residency duration in foraging areas, and even stress or health status\u2014which makes them an unexpectedly valuable focal point in drone and photograph-based monitoring efforts like in the GRANITE project.<\/p>\n\n\n\n<h4 class=\"wp-block-heading has-text-align-center\">Cyamid Life History<\/h4>\n\n\n\n<p>Cyamids are obligate ectoparasites, meaning they spend their entire life on a whale and cannot survive independently in the open ocean. Unlike free-swimming crustaceans, cyamids are permanently attached to the skin or embedded within crevices of the whale\u2019s body, often clinging to roughened areas, scars, embedded barnacles, or calloused skin where they can anchor themselves more securely.<\/p>\n\n\n\n<p>They begin life as tiny juveniles, hatching from eggs carried in the brood pouch of a female cyamid. Rather than undergoing a larval phase in the water column like many marine invertebrates, cyamids develop directly into miniature versions of adults and remain on the whale from birth. This direct development is essential because there\u2019s no safe habitat for a larval cyamid in the open ocean: the host whale is both nursery and home.<\/p>\n\n\n\n<p>Most transmission occurs from mother to calf during the close physical contact of early life. Calves born in the warm lagoons of Baja California, Mexico where gray whales calve and nurse during the winter inherit their cyamid colonies during nursing, rubbing, and swimming alongside their mothers. These early colonizers will multiply as the calf grows and can remain with the whale for years, forming the basis of a persistent, host-specific population.<\/p>\n\n\n\n<p>For <em>Cyamus scammoni<\/em> specifically (our gray whale specific cyamid), adults will breed in the summer just before the southbound migration. Females will have around 1,000 eggs in their brood pouch, although only about a 60% are fertilized (Leung, 1976). These eggs will hatch in the fall while the gray whales take on their southbound migration but they will stay in the safety of the brood pouch for around 2 to 3 months. The juveniles will be released in the winter, when gray whales arrive in the Baja lagoons where they will then find shelter within the crevices of their host gray whale. Juveniles reach maturity during the northbound migration and will be a full-grown brood upon arrival to summer grounds. While the cycle takes about 8 months to complete, there are juveniles found along the gray whales year-round, leading us to believe that there is likely overlap between broods. For our less abundant <em>Cyamus kessleri<\/em>, the life cycle is very similar, but the juveniles reach maturity before the gray whales northbound migration to summer feeding grounds. Also, there are around 300 eggs in the <em>Cyamus kessleri<\/em> brood pouches that have a higher rate of fertilization (75-80%) than <em>Cyamus scammoni<\/em> (60%) (Leung, 1976)<\/p>\n\n\n\n<p>In short, the life of a cyamid is fully bound to the life of a whale. Every migration, dive, foraging event, and scar the whale experiences becomes part of the cyamid\u2019s environment. By studying them, we gain another lens through which to interpret the health, behavior, and ecology of gray whales on the Oregon Coast.<a id=\"_msocom_1\"><\/a><\/p>\n\n\n\n<h4 class=\"wp-block-heading has-text-align-center\">Uses in Cetacean Health Assessments<\/h4>\n\n\n\n<p>As we\u2019ve established, cyamids have unique life histories as ectoparasites and may be valuable indicators in cetacean health assessments across multiple whale species. Because they often congregate around wounds, lesions, and areas of poor skin integrity, their presence and distribution can reveal important clues about a whale&#8217;s physical condition, injury history, and immune response. However, studies that have made these connections have variable results.<\/p>\n\n\n\n<p>In species like North Atlantic right whales (Pettis et al. 2004, Pirotta et al. 2023), harbor porpoises (Lehnert et al. 2021), and gray whales (Raverty et al. 2024), researchers have used visual surveys and photographic analysis to quantify cyamid loads in living, stranded, and hunted whales. Researchers can score cyamid presence by identifying attachment sites (e.g. blowhole, scar, dorsal ridge) and estimating the relative coverage by using standardized reference images to maintain consistency. In these studies, whales with heavy cyamid coverage, especially in sensitive regions like the blowhole, mouthline, and genital area, often show signs of poor health or stress, such as emaciation, scarring from entanglement, or chronic skin conditions. Cyamid coverage is sometimes used alongside body condition indices and lesion scoring to build a more complete health profile (Pirotta et al. 2023). There are also studies that show no connections, or even positive connections between body condition and cyamid coverage (Von Duyke et al. 2016).<\/p>\n\n\n\n<p>While cyamids are often associated with injured, inflamed, or otherwise damaged skin, there is no evidence that points towards cyamids directly damaging the skin themselves. However, more work needs to be done to assess their role in the healing processes. Additionally, it\u2019s been noted that more work is needed on the role of cyamids and disease spread (Overstreet et al. 2009). For the PCFG, there is an iconic whale we call \u201cScarlett\u201d (also known as \u201cScarback\u201d) who has a large scar on the right side of her back that is highly identifiable due to the orange swarm of cyamids that are constantly surrounding the edges of the wound. She has managed to survive and thrive, producing many calves over the years, but questions remain: How are the cyamids affecting the healing process? Are they increasing or decreasing the risk of infection? How does the frequency of large injuries like this on whales contribute to the cyamid population over evolutionary time?<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/osu-wams-blogs-uploads.s3.amazonaws.com\/blogs.dir\/2115\/files\/2025\/04\/cyamidpic-2.png\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"683\" src=\"https:\/\/osu-wams-blogs-uploads.s3.amazonaws.com\/blogs.dir\/2115\/files\/2025\/04\/cyamidpic-2-1024x683.png\" alt=\"\" class=\"wp-image-6119\" srcset=\"https:\/\/osu-wams-blogs-uploads.s3.amazonaws.com\/blogs.dir\/2115\/files\/2025\/04\/cyamidpic-2-1024x683.png 1024w, https:\/\/osu-wams-blogs-uploads.s3.amazonaws.com\/blogs.dir\/2115\/files\/2025\/04\/cyamidpic-2-300x200.png 300w, https:\/\/osu-wams-blogs-uploads.s3.amazonaws.com\/blogs.dir\/2115\/files\/2025\/04\/cyamidpic-2-768x512.png 768w, https:\/\/osu-wams-blogs-uploads.s3.amazonaws.com\/blogs.dir\/2115\/files\/2025\/04\/cyamidpic-2.png 1080w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/a><figcaption class=\"wp-element-caption\">Figure 3. Right side of PCFG icon, \u201cScarlett\u201d showing her massive scar covered with orange aggregations of cyamids.<\/figcaption><\/figure>\n\n\n\n<p>Because whales are complex, highly mobile, long-lived creatures with a constant population of cyamid hitchhikers their skin condition is likely representative of specific to life history, phylogeography, and demographic traits of individuals. While we know that cyamids generally eat sloughed or damaged skin on the whale, what this behavior and symbiosis means for each whale\u2019s individual physiology can be highly complex. Through our high-resolution drone and lateral imagery of the same individuals over time paired with other data sources, such as body condition and prey availability, cyamid scores can offer key insights into how environmental stressors and foraging success affect individual and population-level whale health.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\" \/>\n\n\n\n<p>These tiny crustaceans, clinging to the folds and scars of their hosts, might seem like background noise in a study focused on body condition or foraging ecology\u2014but they\u2019re far from incidental. In my research, I\u2019ve come to see <strong>cyamids as part of the bigger story:<\/strong> <strong>silent indicators of stress, recovery, movement, and resilience<\/strong>. By pairing imagery of PCFG gray whale skin with data on prey availability and environmental conditions, I\u2019m working to understand how foraging success and anthropogenic stressors (such as vessel traffic and entanglements) manifest not just in a whale\u2019s body condition, but in the skin itself. The presence, distribution, and density of cyamids may offer yet another layer of insight into how gray whales are coping with changing ocean conditions. It\u2019s a reminder that even the smallest details, like a patch of whale lice, can help us ask bigger questions about the health, resilience, and future of these cetaceans.<\/p>\n\n\n\n<h5 class=\"wp-block-heading\">References<\/h5>\n\n\n\n<p class=\"has-small-font-size\">Callahan, C.M., n.d.
