Downtown Aquarium Houston has four dated events in October, and the one worth planning around is International Sawfish Day on Saturday, October 17, when the aquarium puts its largetooth sawfish in front of guests on the Shark Voyage train along with conservation stations, crafts, animal encounters and diver question-and-answer sessions.
What the saw is for
The rostrum is the long flat snout, edged with teeth. A largetooth sawfish carries 14 to 24 of them, evenly spaced, down each side, and swings the whole thing from side to side to impale and stun fish it is swimming through. And despite the body shape, sawfish are rays, which is the detail most people get wrong about them.
That rostrum is also what has nearly finished the family off. NOAA Fisheries lists gill nets, trawls and hook-and-line tackle as the gear sawfish are accidentally caught in, and a toothed snout is close to the worst shape an animal could have for getting out of a net again.
Two lists, two words
The aquarium calls the largetooth sawfish endangered, and under United States law that is exactly the right word: NOAA published a final rule listing the species as endangered under the Endangered Species Act on July 12, 2011. On the IUCN Red List, which is a separate list with its own vocabulary, Pristis pristis sits a step higher, at Critically Endangered.
Both are true at once, and the only thing worth taking from the difference is that the global assessment is the bleaker of the two. A facility that keeps a largetooth sawfish and builds a public event around it is doing the thing both listings exist to prompt.
The rest of the month
Home School Day, Wednesday, October 7. Discounted admission for homeschool families, with classroom programs, animal encounters, exhibit chats and diver meet-and-greets through the day.
Spooktacular Pass, October 9 to 12. One pass covering unlimited access to Downtown Aquarium Houston, Kemah Boardwalk and Galveston Island Historic Pleasure Pier over the same weekend, and one free serving of Stingray Reef fish food at the aquarium.
Indigenous Peoples’ Day, Monday, October 12. Animal encounters, educational chats, crafts, storytime and a conservation booth on the connections between Indigenous cultures and environmental stewardship.
Why is a sawfish day worth a visit?
Because very few people will ever see one otherwise. A species listed as endangered under the Endangered Species Act and Critically Endangered globally is not something you come across, and the aquariums holding one are not numerous. An hour with a diver who works with the animal daily is a better introduction than any amount of reading.
October at an aquarium is reliably the month the programming gets good, and Houston is not alone in working the season hard: the New York Aquarium is running its own October run of evenings on the other coast.
Event pages carry the full schedules and ticket details, and the Spooktacular Pass in particular is worth reading twice, because it covers three separate properties on one weekend.
