A question to Clause Sonnet 4.6 via perplexity.ai

“Names like Mola mola and Velell velella, please give me as long a list as you can.”

What a delightful topic! These are called **tautonyms** — scientific names where the genus and species are the same word repeated. Monterey Bay is actually a spectacular place to encounter many of them, since its rich, cold waters host an unusual concentration of these species. Here’s a long list, organized by category:

## Monterey Bay & Nearby Waters

These tautonyms are either resident in or regularly spotted in Monterey Bay:

– ***Mola mola*** — Ocean sunfish; regularly seen basking on the surface right in the bay [1][2]

– ***Velella velella*** — By-the-wind sailor; the beautiful blue hydrozoans that wash up on local beaches in huge numbers every spring, as recently as late April 2026 [3][4]

– ***Remora remora*** — Common remora (suckerfish), found in warm-to-temperate Pacific waters [5][6]

## A Special Mention: Near-Tautonyms

– **Mahi-mahi** (*Coryphaena hippurus*) — “Mahi” in Hawaiian means “very strong,” reduplicated for emphasis; occasionally seen in warmer Monterey waters [11]

The Velella velella washing ashore right now makes this an especially timely question — Monterey beaches are literally carpeted in a tautonym at this very moment! [4][12]
