Picture of unidentified spider

Comments & ID Thoughts

It was in the open area in front of El Morro in Old San Juan in Puerto Rico. It was probably 3 inches long from tip of front legs to tip of back legs in the photo (so scrunched up) and it would chase us until it reachers our shadow and then it would rest until the sun hit it again.

I am not 100% confident, but from what I can gather, this is likely a Puerto Rican brown tarantula, Cyrtopholis portoricae. New World tarantulas like it are technically venomous (like most spiders), but they are not medically significant.

Ozzycat may be correct, but I have reason to believe this is Tliltocatl vagans.
Much for the white banding at leg joints.
