An ocean name should name something in the sea, not merely sound coastal — that is the line the tag holds. Coral, Marlin and Pearl qualify; a name that only feels breezy and blue does not.
Small because the tag is strict
This is a short list, and it stays short on purpose. A name earns the ocean tag when the thing it refers to can be pointed at in the water, recorded so the tag can be checked. Padding it with names that merely sound maritime would make the label worth nothing.
It is also short because each name carries one style label. Pearl could sit under ocean or under gemstones, and whichever it landed on, the other lost it — so the tag is a floor rather than a ceiling, and the archive's search box reaches sea words the label misses.
What it will not tell you
Whether your pet likes water. The tag names the thing in the sea the word points at, and nothing in these registers connects that to how an animal behaves near a bath.
What makes a name an ocean pet name?
It names something in the sea — a creature, a tide, a shore word — recorded so the tag can be checked. A name that merely sounds coastal is not tagged.
Why are there so few ocean names?
Because the test is strict and each name carries a single style label. The live list above shows exactly what currently qualifies rather than a padded count.
Are ocean names only for cats?
No. Each name's own page states which animals its records covered; the sea theme reads well on either a cat or a dog.
Every count on this site is a tally of real registrations: pet licences and shelter intakes published as open data by New York, Seattle, Worcester, Victoria BC, Austin, Montgomery County, Cambridge, Zurich, Basel and seven Australian councils. Popularity here is a source-group share score, so a name common in a small city is not buried by one common in a large one. The source list is North American-heavy by record count, so read the ordering as naming in those places rather than worldwide. Browse the whole catalogue or read how the data is put together.
