garden eel predators

These kinds of observations are often left unpublished so the authors have done a good job of carefully analyzing and presenting their useful observations of the garden eels responses to various types of predators. When they are relaxed or looking for food, garden eels poke their heads out of their burrows and sway in the current. On the four occasions sharks passed between 50 and 220 cm above the eels, the eels fully retracted ~2 s before the shark’s arrival, and then reemerged immediately after the sharks had passed. The consistency between these responses, and the contrast to the Caribbean reef shark encounters at much closer proximity, suggests recognition of predation risk relative to immediate proximity. More on authors: Böhlke & Randall. They escape predators by retreating all of the way into their burrow. One encounter was attributed to a great hammerhead shark (Sphyrna mokarran; ~300 cm TL), which passed over ~300 cm above the eels (Suppl. Close encounter with a queen triggerfish (estimated size ~30 cm TL) also resulted in an extended reaction from the garden eels. They dig into the ground and when predators comes near, they will disappear into their holes Responses to two shark encounters, one with a Caribbean reef shark and one with a great hammerhead shark, at a large distance of separation, elicited a consistent response of partial retraction while remaining exposed throughout the encounter. Fig. Responses to two shark encounters, one with a Caribbean reef shark and one with a great hammerhead shark, at a large distance of separation, elicited a consistent response of partial retraction while remaining exposed throughout the encounter. The consistency between these responses, and the contrast to the Caribbean reef shark encounters at much closer proximity, suggests recognition of predation risk relative to immediate proximity. It is possible, therefore, that the response of the eels may be precautionary for potential commensal predator presence associated with sharks. Create a Matters account to leave a comment. Something with predator avoidance behavior. Electric eels can generate an electrical charge of up to 600 volts in order to stun prey and keep predators at bay. The snake eels then slither their way underneath the garden eels' burrows, attacking them from underneath. It is possible, therefore, that the response of the eels may be precautionary for potential commensal predator presence associated with sharks. Garden eels were present during 3 video surveys conducted in The Bahamas on May 23, 2016 and August 26, 2017 (Suppl. In this encounter, a pair of cubera snappers (estimated size of both ~50 cm TL) passed approximately 30 cm above the eels (Fig. This supported the concept that garden eels can discriminate between larger fish with varying predation risk and adjust their responses accordingly. Gorgasia is one of the two genera that belong to the subfamily Heterocongrinae (common name: Garden Eels). Ben Garver. Triggerfish will chase the eels into their burrows, then ‘dive-bomb’ the sea floor to force them out. Video footage was collected from Baited Remote Underwater Video (BRUV) surveys conducted as part of the Global FinPrint program (globalfinprint.org). But is there anything that can attack and kill and electric eel? Personal theory: wigglers are based on the garden eels. The surveys were conducted to assess shark abundance and biodiversity, but during footage review encounters between garden eels and larger organisms were observed. The splendid garden eel lives in a sandy burrow that it digs tail-first. This would be particularly important on productive reef systems with a high abundance of large-bodied fish, typical of garden eel habitats in The Bahamas, Caribbean region and more broadly across the globe. why not the more typical TL for total length. Please finish your abstract with what these observations would mean (although not significant). If other, additional factors could cause this behavior it doesn't make sense that the eels emerge after the passing of the potential threat. Also, rephrase. Each eel lives in a single burrow and rarely leaves. 1C; Suppl. Spotted garden eels spend the majority of their lives partially embedded in the sea floor. Varied responses suggested an ability to discriminate between organisms and react according to relative predation risk and proximity. Garden eels live in the warmer parts of the Indo-Pacific and Atlantic Oceans and also the Red Sea. ...species of sharks... ? In this encounter, the tilefish moved directly over the garden eel colony and hovered in close proximity to the burrow locations, as if searching for food. Snake eels and triggerfish are the most commonly stated predators, however, the origins of scientific evidence for these statements is unclear. The transparent Eel larva reminds me of the transparent jelly fish which also belongs to the cretaceous period 140 million years ago. Close encounter with a queen triggerfish (estimated size ~30 cm TL) also resulted in an extended reaction from the garden eels. The ability of garden eels to discriminate between large-bodied organisms of varying predation risk would constitute an energetic benefit by minimizing predation risk while maximizing foraging potential. The Spotted garden eel, also known as the spotted snakehead fish, is a small species living in warm waters in the Indian – Pacific region (reaching a maximum of 40 cm in length).) They dig into the ground and when predators comes near, they will disappear into their holes Indeed, queen triggerfish are one of the few recognized predators of garden eels, having been observed chasing garden eels into their burrows, then ‘dive-bombing’ the substrate to dig out and consume them[5]. Brown garden eels (Heteroconger longissimus) were observed during ten encounters with larger fish, and showed variable responses to five different large-bodied species. The Black Garden Eel (Heteroconger perissodon) is a small eel that appears in both Endless Ocean and Endless Ocean: Blue World. If they feel threatened, they retreat backwards into the burrow, where they are safe from predators. Spotted Garden Eels get their names from the spotted patterning on their bodies, and they measure up to 23in (60cm) in length. Prolonged retraction into their burrows for an extended period after the triggerfish left the area, again indicates recognition of direct predation risk and an adjusted response to the encounter with this species. Five of the ten encounters were attributed to Caribbean reef sharks (Carcharhinus perezi; estimated size range = 150 to 180 cm total length [TL]), an improbable predator of garden eels, which passed approximately between 50 to 600 cm above the garden eels (Fig. Observations were derived from baited remote underwater video footage collected as part of Global FinPrint, funded by Paul G. Allen Philanthropies. It is possible, therefore, that the response of the eels may be precautionary for potential commensal predator presence associated with sharks. Brown garden eels were observed during ten encounters with large-bodied fish at three reef sites (Fig. Supplementary Figure 2. It might be better to have a first sentence that introduces garden eels more generally. My only comment that is also made in the specific sections, is to add new sentences to the beginning of the Abstract and Intro that give the reader some basic background on the life histories of garden eels, so the text does not only focus on the predation issue and ignore how garden eels live.
