Spectral Barbed Spider

There is one tameable creature with this look.

Spectral Barbed Spider
Can Be Tamed
Little Scales Daycare, Valdrakken, Thaldraszus
You can spawn this spectral spider during the Off the Page daily quest at Little Scales Daycare in Valdrakken. Daily quests in this area are only available after you unlock them by completing the "Whelp Daycare" storyline (added in Patch 10.1.5) up to the quest: What's a Duck?. The 'Off the Page' daily only appears every now and then, so you'll most likely have to keep checking for it. During this quest, you read from a storybook and summon a random NPC. You need for Osthilde to appear, as she's the one who summons Death Skitterers in combat, otherwise you can feign death and the NPC will despawn after about 10 seconds and you can try again (if you keep a small distance from the spawning NPC it's possible to avoid aggroing it so it'll despawn after about 10 seconds anyway!) You may have to fight Osthilde for a while before the Death Skitterers spawn, so beware of killing her too quickly. Note that if you haven't unlocked the Daycare dailies yet, it's possible to get someone else to do the summon, as the quest isn't phased.
Level scaling: Most NPCs will scale with the Hunter's level, within the constraints of their level range. Hunters can tame regular NPCs up to 2 levels higher than them, but can only tame elite NPCs of the hunter's level or below.
