- "The Streeler is a giant snail that changes colour on an hourly basis and deposits behind it a trail so venomous that it shrivels and burns all vegetation over which it passes. The Streeler is native to several African countries, though it has been successfully raised by wizards in Europe, Asia and the Americas."
- — Newt Scamander, Fantastic Beasts and Where to Find Them[src]
The Streeler changed colour hourly, and left behind a trail of venom so toxic that it burned all vegetation that it touched. Streelers had sharp spikes on their shells, which also injected venom. This defence was most likely to scare off or kill its attackers, such as birds and small to medium sized rodents.
In 1992 and 1993, The Magical Menagerie in Diagon Alley housed and sold orange Streelers for purchase. Harry Potter, Ronald Weasley and Hermione Granger saw some of these creatures for sale when they entered the shop in August 1995, amongst others.
