Because we will often change the name of a product late in the development cycle, we use in house nicknames for all development projects. The LulzBot TAZ line of printers are named after trees, the LulzBot Mini line is named after flowers, and the accessories are named after fish. Here's a guide to help you associate the development names with actual products.
*"Arowana" - Extruder Fan Add-on
*"Barracuda" - Flexystruder
*"Cobia" - Dual Extruder
*"Dorado" - FlexyDualie
*"Escolar" - Cat Guard
*"Fangtooth" - This is an all metal hotend for 3mm filament based off of the Reprap Discount Hexagon nozzle, but with changes to improve printability and make the device safer.
*"Guppy" - This is an toolhead for 1.75mm filament. It's also based off of the Hexagon nozzle and has the same tweaks as the 3mm variant.
*"Halibut" - This is a standalone paste extruder currently in the early prototype phase (https://forum.lulzbot.com/viewtopic.php?f=29&t=1004&p=5186&hilit=paste+extruder#p5186)
