Oh Deer!
Philippine deer (Chamorro: binadu, scientific name: Rusa marianna) were introduced to Guam in the 1770s & later the Northern Marianas. Deer hunting is important to CNMI culture. In the Philippines, deer are vulnerable to extinction. But here, deer are invasive & damage native habitat 🦌

I had the delight of meeting these (or a related species) and other very large snails while studying abroad in Ecuador back in 2013
Why are there giant land snails in the tropics (e.g. these Ecuadorian species, giant African snails), but giant slugs in temperate zones?

Diamondback Squids (Thysanoteuthis rhombus) lay their eggs in giant pink slinkies. These egg masses are made up of two threads of eggs wrapped around a cylinder of mucus.
These egg masses contain 35,000 to 75,000 eggs and have a length of 60 cm to 180 cm long with a diameter of 11 to 30 cm.

Lovely piece from @anngawel.bsky.social on akaleha' tree snails in Guam & the CNMI. Dr. Gawel visited Rota to hear from elders on how they collected & used akaleha'. And she helped me map living akaleha' & showed me an akaleha' site I didn't know! #JoyOfMolluscs

- learned in 8th grade that paid to play with slugs = "biology"
- research opportunities in undergrad & grad school for shelled snails, so I expanded my horizons to the shelly

Did you know -
Hermit crabs use snail skeletons to cover their butts 😱
🐚 Hermit crabs don't build their shells
🐌 But snails do!
A snail's shell is its skeleton and grows as the snail grows. Hermit crabs use dead snails' shells protect their soft backsides. Creepy!

These 2 showed up on our doorstep just days after my birthday, when they were maybe 2 months old. Raising them is the unexpected birthday gift that keeps on giving 🖤🖤

Snail shells in traditional Pacific arts:
🐚In the Marianas, Chamorro & Refaluwasch people used akaleha' tree snails to make beaded bags & jewelry
🌏Many Pacific cultures use seashells for islands in stick chart maps, combining art, science, & geography

Clara Peeters clearly had excellent taste in still-life subject #JoyOfMolluscs 🐚
The Prado, national art gallery of Spain, founded in 1819, only hosted its first solo exhibition of a female artist's work in 2016, 17thc painter Clara Peeters (her work below), not untypical of many major galleries across the world....

Out in the CNMI here, where I currently am, the best answer I know of is the local Golden Huntsman, Olios sp. Relatively abundant among the spiders here, but undescribed regardless.

Some invasive inverts in the Mariana Islands
1️⃣ coconut rhinoceros beetle 🪲
These jerks are on Rota, but our invasive species team keeps them contained 🏅
2️⃣ succineid snails 🐌
We might have native ones, too, but this one was at my apt, so I think it's introduced
