This creature’s spines are massive in comparison to its body, and appear to be bladed.
Spear Urchin CR 4
AC 17, touch 5, flat-footed 17 (–4 Dex, +12 natural, –1 size)
hp 42 (5d8+20)
Fort +8, Ref –3, Will +1
Defensive Abilities all-around vision, stability (see the hunter urchin); Immune mind-affecting effects
When a creature attacks a spear urchin with an unarmed strike or natural attack, or with a manufactured melee weapon while adjacent to the urchin, the urchin automatically gains a free attack with its spines. In addition, a spear urchin can fire up to 2 spines each round with a range increment of 30 feet. As long as its target is within 30 feet, a spear urchin ignores Dexterity and size penalties on ranged attack rolls, but beyond this range the penalties function normally. A spear urchin’s spines function equally well underwater and above water.
Environment warm oceans or coastlines
Organization solitary, pair, or cluster (3–6)
These brightly colored creatures can fire spines like javelins, relying upon poison to slow down prey or eventually immobilize it so they can crawl over to feed.
Much more dangerous than their smaller kin, giant sea urchins are dangerous predators of opportunity. With the exception of the hunter urchin, giant sea urchins lie in wait for food to come to them, typically carried within reach of their attacks via ocean currents or, more commonly, tides.
