Please be stealthy and replace with precision. Pinnipedia?
Usually on the dock/island, right in front of the cache location.
The scientific name for Seals, Sea Lions, and walruses is Pinnipedia. Its Latin root means "fin-footed" and refers to the modification of limbs to flippers. Pinnipeds have four flippers – one pair in front and one pair in back. Pinnipeds share five common characteristics with other mammals: they’re warm-blooded, give birth, nurse their young, breathe air, and have hair. Since they live in the marine environment and they find their food at sea, pinnipeds are marine mammals.
Other marine mammals include whales and sea otters. Although they spend most of their lives in the water, pinnipeds, unlike whales and dolphins, are also dependent upon land. Pinnipeds may come ashore, or in this case, the docks, periodically to rest and bask in the sun.
SEALS = Seals are smaller and have a sleeker, torpedo type of shape. They move with a rhythmic sliding or shuffling motion, and they don’t use their flippers to support their body. Harbor seals are very shy and rarely bark.
SEA LIONS = Sea lions are larger, with longer flippers and are very vocal. They can support themselves on their two front flippers and actually walk. They are more territorial and more aggressive than seals. Those here you will often hear barking.
