(1) teacher key non-editable PDF handout.(1) student handout non-editable PDF handout.This documentary, available on YouTube with well over 11 million views (can you believe) this video and lesson will have your kids questioning whether sharks are scavengers, or highly adapted top predators. That, however, is the very reason why I made this into a resource.

If the title of this video was not enough evidence, it should be noted that this video has scientific inaccuracies. I've made a 20 question PDF anticipation guide with a teacher key, and an animated 8 slide class PPT key, that follow this interesting video. Overall, this study provides evidence that fully protected marine reserves can encourage seafloor habitats to recover, which in turn, can create a number of benefits that flow back to other species, including those of commercial importance.Product Description: Kids love sharks, and teachers are always looking for teachable moments: Enter the video ' Sharks: Scavengers of the Seas' (49 min).

Limited recovery of these ecosystem components may be due to the relatively small size (2.67 km2) and young age of the reserve (<5 years), both of which might have limited the extent of any benefits afforded to mobile fauna and fish communities. Similarly, the use of baited underwater video cameras revealed no difference in the abundance and size of fish between the reserve and outside. In contrast, there was little difference in the abundance of mobile benthic fauna, such as crabs and starfish, between the reserve and outside. In addition, the greater abundance of complex habitats within the reserve appeared to providing nursery habitat for juvenile cod (Gadus morhua) and scallops (Pecten maximus and Aequipecten opercularis). Both results are consistent with the hypothesis that protecting areas from fishing can encourage seafloor habitats to recover.

Likewise, the overall composition of epifaunal communities in and outside the reserve was significantly different. A combination of photo and diver surveys revealed live maerl (Phymatolithon calcareum), macroalgae, sponges, hydroids, feather stars and eyelash worms (Myxicola infundibulum) to be significantly more abundant within the marine reserve than on surrounding fishing grounds. This study therefore investigated the dynamics of both benthic communities and fish populations within a recently established, fully protected marine reserve in Lamlash Bay, Isle of Arran, United Kingdom, over a four year period. Furthermore, out of the few studies published on MPAs in temperate waters, the majority focus on specific ecological or fishery components rather than investigating the ecosystem as a whole. Despite recent efforts to increase the global coverage of marine protected areas (MPAs), studies investigating the effectiveness of marine protected areas within temperate waters remain scarce.
