Scalloped hammerheads 🦈 we counted more than a hundred. What would be your guess? 🎥 Video by me @watermelodie with @divevolk. 📷 cover photo on this reel from the same dive by Alex Dawson 🤿 Dive buddy @alex_dawson_photography with no bubbles on our @divesoft #rebreatherdiving #sidemountrebreather These sharks have a very sophisticated navigation system, using the environment as a map. 🗺 Most often, scalloped hammerheads will be seen in large schools, sometimes numbering in the hundreds of individuals. They spend most of the day close to shore moving into deeper waters at night in the search for food. Although the schooling has sexual reasons, it also operates as a means of protection, particularly for the younger sharks. They tend to be allocated the upper regions of the school, closest to the surface. Some species of hammerheads migrate during the warmer months of the year in the search for cooler water, particularly the shallow water sharks like the scalloped hammerhead. Normally they pay little attention to divers and exhibit no aggression or changes in behaviour. 💙🤿
