Although sea spiders are not true spiders, or even arachnids, their traditional classification as chelicerates would place them closer to true spiders than to other well-known arthropod groups, such as insects or crustaceans.
If you have an HDTV, we strongly recommend that you buy a Blu-ray player rather than a standard DVD player. Prices for Blu-ray players now start at less than $100, but expect to pay a bit more for a major-brand player that has 3D and wireless capbility.
In fact, you can greatly improve the playback quality of your current DVDs when using a Blu-ray player. A standard DVD player plays your DVDs at a video resolution of 480i. That produces a good quality picture, but it won't take advantage of your HDTV's higher resolution. A Blu-ray player can upconvert your DVDs to 720p, 1080i or 1080p, depending on your HDTV and the connections you are using. While this will not provide the same high-definition quality of a Blu-ray movie, it should definitely improve the look of your DVDs when compared with a standard DVD player output.
