Friday Squid Blogging: Participatory Squid Dissection in October in Tennessee

I feel like someone who reads this blog will want to go to this:

Families are invited to dive into the fascinating world of marine biology during an exciting, hands-on Family Squid Dissection at the Hands-On Science Center. Designed for curious learners of all ages, this unique experience combines an interactive lesson with the opportunity to explore the anatomy and adaptations of real ocean life.

[…]

During the guided squid dissection, each family will work together to examine a squid up close, exploring its organs, structures, and specialized features. The experience provides a memorable opportunity for children and adults to see firsthand how the anatomy of a squid helps it survive in its underwater environment.

If you go, take pictures.

As usual, you can also use this squid post to talk about the security stories in the news that I haven’t covered.

Exciting! I hope each family gets to grill theirs afterward

In other news, the company formerly known as Accellion is in the news with guidance to customers to shut down their software for 6 hours tomorrow.

@ Andrew,

With regards,

“I hope each family gets to grill theirs afterward”

Not all squid are either edible or palatable.

In fact quite a few “smell of ammonia” / urine and last weeks Friday Squid gave me pause to think about it.

Ammonia is a natural by product of a carnivorous diet… And some “ammoniacal” squid species have a sufficient quantity to make them not just smell of pee but made inedible by the ammonia ions in their body.

Interestingly ammonia ions are slightly lighter than sodium ions thus the resulting solution is lighter than seawater thus if stored in an internal sac gives buoyancy in a dozen or so squid species for little or no energy input.

Admittedly these dozen or so squid species are of the deep-sea or even Giant-squid so would not be considered for the dinner table anyway. Also as they are rarely caught and sufficiently rare that they are considered for either chucking back or made available for science / research.

And that’s about all this Dad can remember from the obligatory parent and child visit to a natural history museum and aquarium 😉
