Building Trees

October 21, 2020

I built the tree for the Dive Gear section. All the multi-subject pages have exploded into multiple single-subject pages, and everything then needs to be re-organized. It is very fussy and time-consuming. The worst part was doing the Dive Sites section, because that involved not only organizing things logically, but also geographically. Dive Sites and Artificial Reefs are all tangled up in each other as well, which was fun to sort out. Now up to 1058 pages and posts, with just the Artifacts section left to do.

Later ...

I finished putting in the Artifacts section. The total number of pages now stands at 1163, although I'm sure that will go up as I find things I missed.

Octopus

Octopus vulgaris

Size: see below

Habitat: rocks and coral reefs, all depths

Notes:

The Common Octopus is the most studied of all octopus species. Its natural range extends from the Mediterranean Sea and the southern coast of England to at least Senegal in Africa, as well as the Azores, Canary Islands, and Cape Verde Islands. In the western Atlantic, it ranges from Texas and Florida to New England, although uncommon in colder northern waters. Typical habitat is rocks and coral reefs. Young are planktonic, and total lifespan is only 12-18 months.

O. vulgaris grows to 25 cm in mantle length with arms up to 1 m long. They can weigh up to 20 pounds, although they are usually much smaller. O. vulgaris is caught by bottom trawls on a huge scale off the northwestern coast of Africa. More than 20,000 tons are harvested annually.
