Frogs and Crocs
(An extract from The Torah Encyclopedia of the Animal Kingdom by Rabbi Natan
Slifkin, currently in preparation. For the pictures that accompany this

The second plague to befall Egypt was that of tzefardea. It is widely
believed that the term tzefardea refers to frogs, but Ibn Ezra notes that
there are actually two views on this matter:
"The commentators differed in their understanding of the word tzefarde'im.
Many said it referred to a sort of fish found in Egypt, called al-timsah in
Arabic, which comes out of the river and seizes human beings. Others say
they are the creatures found in most of the rivers and that they make a
sound. This explanation, which is well known, seems correct in my view."
(Ibn Ezra to Exodus 7:27)
The former explanation is describing a crocodile. It is referred to as a
fish, even though it is a reptile, because the Torah concept of fish also
includes other aquatic creatures. Support for this identification is
advanced from the description of how the frog plague ceased. The Midrash
comments on the statement that the tzefarde'im shall remain in the river:
" 'The tzefarde'im shall retreat from you and your courtiers and your
people; they shall remain only in the Nile' (Exodus 8:7) - Rabbi Yitzchak
said, There are still deadly beasts in it that come out and kill people
every year ... Moshe did not pray that the tzefarde'im be wiped out, only
that they not harm Pharaoh, as it says, 'And Moshe cried out to the Lord in
the matter of the tzefarde'im which He had inflicted upon Pharaoh'(Exodus
8:8)." (Midrash haGadol[1])
Rabbeinu Bachya elaborates at greater length:
"Moshe's words in his prayer stayed true for that time and for all
generations. In accordance with his words, 'they shall remain only in the
Nile,' to this very day the creeping water creature known as the al-timsah
remains there. There it lives, and it is said that sometimes it comes out of
the Nile where it lives, rising onto the river's edge and swallowing
whatever it finds, even two or three humans at a time. Neither spear nor
arrow can overcome its body, unless aimed for its belly. Physicians say it
is venomous and that touching its body, even after its death, is harmful to
man. It is of the tzefardea type, and from the power of Moshe's words, this
creature remains there... This is also how Rabbeinu Chananel explained it,
and regarding this it states, 'Speak of all His wonders' (Psalms 105:2)."
(Rabbeinu Bachya, Exodus 10:19)
According to the second identification, preferred by Ibn Ezra, the tzefardea
is the commonly found animal that makes a sound - the frog. This is also the
explanation preferred by others:
"Some say it looks like a fish, that it is the timsah, which moves its upper
jaw, unlike all other lowly creatures, and that it seizes humans and animals
passing by the river's edge. But the correct explanation is that they are
the known creatures of rivers and pools." (Sefer haMivchar[2])
We find the following evaluation in Sefer HaToda'ah:
"This type of destructive tzefardea did not exist in the Nile previously.
After it was then created, it remains in the Egyptian river forever. It
grows in the Nile to a great size, and damages and swallows creatures big
and small. It is the tamsah, which is found in the Nile until today, as a
memorial to that plague. And there are some of the commentaries who say that
the tzefardea referred to here is the small croaking creature, and so it
appears from the words of our rabbis in the midrashos." (Sefer HaToda'ah 23)
The midrashim to which he refers describe the frog as a small and weak
creature, prey to snakes and aquatic creatures, that is extremely vocal.
This description can only match the frog and does not match the crocodile at
all.
What of the etymology of the name tzefardea - does that give an indication
either way? Some claim it to be a word from an unknown foreign source.[3] It
may be a combination of the root tzafar, meaning to chirp (as frogs do),
along with the root rada, "muddy marsh," which is the frog's favored
habitat. But there are those who state that the name tzefardea is a
combination of two words, tzipor de'ah, "the bird of knowledge." Some
explain this to refer to the frog, which chirps like a bird and knows when
to stop:
"Tzefardea - a creeping creatures that emits cries all night, until morning,
and it is tzipor da, 'the knowing bird,' that it knows the time of morning,
to cease from its cries." (Chatzi Menasheh[4])
There is another explanation of "the knowing bird" that is more difficult to
ascribe to either animal:
"Ba-tzefarde'im" - what is this word, tzefarde'a? There was a bird (tzipor)
in the Nile that had intelligence (de'a), and when this bird called to them
they came, and so they were named after this bird with intelligence:
tzefar-de'a. (Midrash Lekach Tov to Exodus 7:28; cf. Yalkut Shimoni 7:182)
Neither frogs nor crocodiles are known to respond to the calls of birds. But
there is a suggestion based on this midrash that there are similar reasons
for positing that tzefardea refers to the crocodile.[5] There is an account
by Herodotus, who visited Egypt in 459 B.C.E., of a small bird picking food
from the teeth of a gaping crocodile. It has been suggested that this refers
to the Egyptian plover, Pluvianus aegyptius, which has since also earned the
name of "crocodile plover." It is said that while the crocodile rests with
its mouth open, these intelligent birds peck at the crocodile's teeth in
search of parasites. The crocodile makes no attempt to eat the bird and is
apparently aware of its benefits. The bird is extremely cautious and gives a
call when fleeing from danger, thus also warning the crocodile. Perhaps the
tzefardea is the crocodile, named after its symbiotic partner, the
intelligent bird that cleans it and warns it of danger.
A problem with this charming explanation is that the described phenomenon
may not
actually be true. Whether such a mutual relationship exists is hard to
determine; in the zoological literature, few apart from Herodotus are
actually recorded as having seen it.[6] One ornithologist claims that ".no
reliable observer since then has seen [it] acting as a crocodile
toothpick... The myth has been perpetuated in the literature and needs
finally to be laid to rest, unless contrary proof can be found."[7] On the
other hand, Israel's legendary crocodile hunter Ofer Kobi, who spent decades
hunting and farming crocodiles in Africa, informed me that he has observed
it.[8] If it does exist, it is rare, and seems more likely to be
opportunistic rather than symbiotic.
In conclusion, while there are those who have explained the tzefardea of
Egypt to refer to the crocodile, its usage in Midrashic sources and its
etymology indicate that the frog is the more likely contender, as several of
the commentaries conclude. Some suggest that the name tzefardea refers to
amphibious herptiles in general, and could thereby include both frogs and
crocodiles. This is the explanation given by the Netziv, who states that
whereas most of Egypt was plagued only by frogs, Pharaoh and his entourage
were attacked by crocodiles.[9]
